New Total Solar Irradiation (TSI) baseline value - solar min measured lower in 2008

By Anthony Watts, Watts Up With That

From a new paper by Dr. Greg Kopp and Dr. Judith Lean, new finding on the solar minimum TSI in 2008:

The most probable value of total solar irradiance representative of solar minimum is 1360.8 plus/minus 0.5 W m-2, lower than the canonical value of 1365.4 plus/minus 1.3 W m-2 recommended a decade ago. This new value, measured by SORCE/TIM, is validated by irradiance comparisons to a NIST‐calibrated cryogenic radiometer in the new TSI Radiometer Facility. Uncorrected scattering and diffraction are shown to cause erroneously high readings in non‐TIM instruments.

That’s lower by 4.6 watts per square meter. This may mean that many climate models will have to be reinitialized if it is decided that this value they derive from SORCE is more accurate than the value established previously.

(d) The daily sunspot numbers indicate fluctuating levels of solar activity for the duration of the database

By way of a forcing comparison to this suggested revision, according to NOAA ESRL: The total effective climate forcing for all GHGs including CO2 and ozone (O3) from the beginning of the industrial revolution in 1750 to the year 2000 is 2.63 watts per square meter.

So a change of 4.6 watts per square meter to the old baseline TSI is more than double the total GHG forcings. That’s not chump change. It will be interesting to see how this shakes out in models. It is important to note this caveat from their abstract:

TIM’s lower solar irradiance value is not a change in the Sun’s output, whose variations it detects with stability comparable or superior to prior measurements; instead, its significance is in advancing the capability of monitoring solar irradiance variations.

Improved measurements of sun to advance understanding of climate change

From Eurekalert: WASHINGTON - Scientists have taken a major step toward accurately determining the amount of energy that the sun provides to Earth, and how variations in that energy may contribute to climate change.

In a new study of laboratory and satellite data, researchers report a lower value of that energy, known as total solar irradiance, than previously measured and demonstrate that the satellite instrument that made the measurement - which has a new optical design and was calibrated in a new way - has significantly improved the accuracy and consistency of such measurements.

The new findings give confidence, the researchers say, that other, newer satellites expected to launch starting early this year will measure total solar irradiance with adequate repeatability - and with little enough uncertainty - to help resolve the long-standing question of how significant a contributor solar fluctuations are to the rising average global temperature of the planet.

“Improved accuracies and stabilities in the long-term total solar irradiance record mean improved estimates of the sun’s influence on Earth’s climate,” said Greg Kopp of the Laboratory for Atmospheric and Space Physics (LASP) of the University of Colorado Boulder. Kopp, who led the study, and Judith Lean of the Naval Research Laboratory, in Washington, D.C., published their findings today in Geophysical Research Letters, a journal of the American Geophysical Union.

The new work will help advance scientists’ ability to understand the contribution of natural versus anthropogenic causes of climate change, the scientists said. That’s because the research improves the accuracy of the continuous, 32-year record of total solar irradiance, or TSI. Energy from the sun is the primary energy input driving Earth’s climate, which scientific consensus indicates has been warming since the Industrial Revolution.

Lean specializes in the effects of the sun on climate and space weather. She said, “Scientists estimating Earth’s climate sensitivities need accurate and stable solar irradiance records to know exactly how much warming to attribute to changes in the sun’s output, versus anthropogenic or other natural forcings.”

The new, lower TSI value was measured by the LASP-built Total Irradiance Monitor (TIM) instrument on the NASA Solar Radiation and Climate Experiment (SORCE) spacecraft. Tests at a new calibration facility at LASP verify the lower TSI value. The ground-based calibration facility enables scientists to validate their instruments under on-orbit conditions against a reference standard calibrated by the National Institute of Standards and Technology (NIST). Before the development of the calibration facility, solar irradiance instruments would frequently return different measurements from each other, depending on their calibration. To maintain a long-term record of the sun’s output through time, scientists had to rely on overlapping measurements that allowed them to intercalibrate among instruments.

Kopp said, “The calibration facility indicates that the TIM is producing the most accurate total solar irradiance results to date, providing a baseline value that allows us to make the entire 32-year record more accurate. This baseline value will also help ensure that we can maintain this important climate data record for years into the future, reducing the risks from a potential gap in spacecraft measurements.”

Lean said, “We are eager to see how this lower irradiance value affects global climate models, which use various parameters to reproduce current climate: incoming solar radiation is a decisive factor. An improved and extended solar data record will make it easier for us to understand how fluctuations in the sun’s energy output over time affect temperatures, and how Earth’s climate responds to radiative forcing.”

Lean’s model, which is now adjusted to the new lower absolute TSI values, reproduces with high fidelity the TSI variations that TIM observes and indicates that solar irradiance levels during the recent prolonged solar minimum period were likely comparable to levels in past solar minima. Using this model, Lean estimates that solar variability produces about 0.1 Celsius (0.18 Fahrenheit) global warming during the 11-year solar cycle, but is likely not the main cause of global warming in the past three decades.

December United States Climate Review by NCDC

The temperature and precipitation pattern for December 2010 matched what is expected from the negative Arctic Oscillation, especially east of the Rockies.

Florida and Georgia had the coldest December in the 1895-2010 record and the Carolinas ranked 3rd coldest. A total of 11 states from the Ohio Valley to the Gulf Coast had the tenth coldest, or colder, December in 2010.

Precipitation was below normal from the Southern Plains and Southeast to the southern Great Lakes, with Louisiana and Mississippi having the 3rd driest December and 4 other states ranking in the top ten driest category.

As a result, drought expanded in the southern tier states, especially the southern Plains and Southeast. By the end of the month, 24 percent of the contiguous U.S. was classified in moderate to extreme drought, according to the U.S. Drought Monitor. The precipitation pattern over the West reflected a combination of La Nina and Arctic Oscillation influences.

Temperature Highlights

The national temperature, when averaged across the contiguous U.S., was near normal in December, only 0.4 degrees F (0.2 degrees C) below the long-term average.

Regionally, temperatures in the Southwest (2nd warmest) and West (10th warmest) climate regions were much above normal. In contrast, much below normal temperatures dominated the Southeast (3rd coldest) and Central (9th coldest) climate regions.

Both Florida and Georgia experienced their coldest December on record. The average statewide temperature in Florida was more than 9 degrees F (5.0 degrees C) below the 20th century average, as every climate division in the state experienced an average December temperature that was record cold.

In addition, several cities including - Miami, West Palm, Ft Lauderdale, Daytona, Orlando, Tampa, and Tallahassee Icecap Note: virtually all cities and stations - had thier coldest December on record.

ICECAP NOTE: For Florida, it was statewide the coldest December on record beating out 1935.

Also note that Tampa NWS office in Rusking reported 2010 in many locations in west and southwest Florida had more days with temperatures failing to reach 60F than any year in history.

Several other states including - North Carolina and South Carolina (3rd coldest), West Virginia (4th), Virginia and Alabama (5th), Tennessee (6th), Kentucky (7th), Mississippi (8th), and Ohio (10th) - had a temperature that was among their ten coldest based on records that date back to 1895.

The average temperature for several states in the West during the month of December was much above-normal. New Mexico had its second warmest December, both Colorado and Arizona had their fourth warmest, while it was Utah’s eighth and Nevada’s tenth warmest such December.

Precipitation Highlights

Precipitation in December, when averaged across the contiguous U.S., was normal, only 0.01 inch (0.3 mm) below the 20th century average. Record precipitation amounts in the west were offset by the dryness in the southern Plains and Southeast.

The persistent on-shore flow from the Pacific contributed to the third wettest December for the West climate region. These dissipated by the time they reached the South and East, contributing to the second driest December in the South climate region.

Both Nevada and Utah had their wettest December on record. Other states that were much wetter-than-normal were Minnesota (4th wettest), Maine (5th wettest), North Dakota (6th wettest), California (7th wettest), South Dakota (8th wettest) and Oregon (10th wettest).

In the South and East several states were drier-than-normal as both Mississippi and Louisiana experienced their third driest December on record. Elsewhere, Kansas had its sixth driest December, Alabama its seventh, Arkansas its eighth, and Delaware its tenth.

Claim 2010 tied with warmest year ever lacks historical perspective

By Art Horn, Icecap Meteorologist

You would think that NOAA, the National Oceanographic and Atmospheric Administration would be an objective and sober reviewer of temperature data. Apparently they are not. NOAA has proclaimed that 2010 was tied with 2005 as the “warmest year on record.” At first this sounds impressive. But as with all political proclamations there is always more to the story. The statement “warmest on record” means the period of time since 1880 that temperature has been measured with thermometers. To say the 2010 was tied with the warmest year on record is essentially meaningless when viewed in a true historical context.

If NOAA was truly objective in their analysis of this 130 year period of temperature they would acknowledge that 130 years of record in the long history of climate is insignificant to the extreme. The reason they do not give this record its true historical context is because their statement is really political. Their true message is that global warming is causing the warm weather and that we need to abandon fossil fuels and somehow change to “renewable” energy sources.

If one takes a serious, adult look at the variability of weather and climate over time you find amazing events. In the winter of 1249 it was so warm in England that people did not need winter clothes. They walked about in summer dress. It was so warm people thought the seasons had changed. There was no frost in England the entire winter. Can you imagine what NOAA would say if that happened next year? But it did happen, 762 years ago and burning fossil fuels had nothing to do with it. In the winter of 1717 there was so much snow in Massachusetts in late February and early March, single story houses were buried. A series of 4 storms produced so much snow that by the time the storms ended there was 10 to 15 feet of snow on the ground. People had to tunnel from one home to another to check on each other. Search parties were organized in Medford Massachusetts to find the poor and the elderly. One widow was known to have several children. They found her house from the smoke coming up through the snow. After digging down into the snow the rescuers entered through a window and found her and her children alive. They were burning the furniture to heat the house. If this happened today we would be told it was because of “climate disruption” the new offspring our government has given birth to as a replacement for “climate change.”

Isotopes of oxygen analyzed from deep ice cores drilled in Greenland’s massive two mile thick ice sheets show that today’s “record warmth” is not even close to how warm it’s been in the recent past. These oxygen isotopes can act as a proxy or substitute for temperature. What they reveal is that the earth was much warmer than today for most of the last 10,000 years by 1 to 4 degrees Fahrenheit. The entire warming of the last 160 years is just 1 degree Fahrenheit, half of which took place between 1910 and 1945 when humans could not have had any effect. In fact these ice cores reveal that earth’s temperature has been rising for 200 years, rebounding from a 500 year cold period known as the “Little Ice Age.” Further examination of the ice core temperatures show that earth’s temperature peaked some 3,300 years ago in the Minoan Warm Period and has been falling ever since.

Today’s “record warmth” may be fleeting. Statements by agenda driven government agencies can’t be trusted. Real scientific data, not shadowy half truths show that earth’s temperature is falling and has fallen nearly 4 degrees Fahrenheit in the last 3,000 years. Remember, when someone only reveals part of the truth it means they have something to hide.

See SPPI post on the December to Remember here. See Are Huge Northeast Snowstorms Due to Global Warming here. See story on last year’s incredible winter here.

Also seein this Real Science post, Derek Arndt, who heads the climate monitoring branch at NOAA’s National Climatic Data Center in Asheville, N.C., said the new data should be viewed in the context of the record retreat of snow cover in the Northern Hemisphere at the end of the melt season and a near-record retreat of Arctic sea ice.

“Together across the board, it was an unusual year, and a year that in many ways was a culmination of what we’ve been seeing for the past several years,” Arndt said. in WAPO.

Record retreat meaning second largest winter snow cover on record.

Given this twisted logic, last season with all-time record snows in the DC area meant all-time record snowmelt as it disappeared. Reminds me of the ridiculous NOAA spokesman statement last year that global warming helped explain the record DC snow thanks to storm track shifting north and more moisture from the Great Lakes. Clueless.

Land fizzing like soda pop: farmer says CO2 injected underground is leaking

By: Bob Weber and Jennifer Graham, The Canadian Press

A Saskatchewan farm couple whose land lies over the world’s largest carbon capture and storage project says greenhouse gases seeping from the soil are killing animals and sending groundwater foaming to the surface like shaken soda pop.

The gases were supposed to have been injected permanently underground.

Cameron and Jane Kerr own nine quarter-sections of land above the Weyburn oilfield in eastern Saskatchewan. They released a consultant’s report Tuesday that links high concentrations of carbon dioxide in their soil to 6,000 tonnes of the gas injected underground every day by energy giant Cenovus (TSX:CVE) in an attempt to enhance oil recovery and fight climate change.

“We knew, obviously, there was something wrong,” said Jane Kerr.

A Cenovus spokeswoman said the company doubts those findings. She pointed out they contradict years of research from other scientists.

“It’s not what we believe,” said Rhona Delfrari.

Since 2000, Cenovus has injected about 16 million tonnes of carbon dioxide underground to force more oil from an aging field and safely store greenhouse gases that would otherwise contribute to climate change.

But in 2005, the Kerrs began noticing algae blooms, clots of foam and multicoloured scum in two ponds at the bottom of a gravel quarry on their land. Sometimes, the ponds bubbled. Small animals - cats, rabbits and goats - were regularly found dead a few metres away.

Then there were the explosions.

“At night we could hear this sort of bang like a cannon going off,” said Jane Kerr, 58. “We’d go out and check the gravel pit and, in the walls, it (had) blown a hole in the side and there would be all this foaming coming out of this hole.”

“Just like you shook up a bottle of Coke and had your finger over it and let it spray,” added her husband.

The water, said Jane Kerr, came out of the ground carbonated.

“It would fizz and foam.”

Alarmed, the couple left their farm and moved to Regina.

“It was getting too dangerous to live there,” Cameron Kerr said.

He said provincial inspectors did a one-time check of air quality. Eventually, the Kerrs paid a consultant for a study.

Paul Lafleur of Petro-Find Geochem found carbon dioxide concentrations in the soil last summer that averaged about 23,000 parts per million - several times those typically found in field soils. Concentrations peaked at 110,607 parts per million.

Lafleur also used the mix of carbon isotopes he found in the gas to trace its source.

“The ... source of the high concentrations of CO2 in the soils of the Kerr property is clearly the anthropogenic CO2 injected into the Weyburn reservoir,” he wrote.

“The survey also demonstrates that the overlying thick cap rock of anhydrite over the Weyburn reservoir is not an impermeable barrier to the upward movement of light hydrocarbons and CO2 as is generally thought.”

Delfrari said Cenovus has hired three independent consultants to evaluate Lafleur’s work.

She pointed to a 2004 report on the project by Saskatchewan’s Petroleum Training and Research Centre, an agency bringing together government, academics and industry. That report found that after four years of injection, there was no indication carbon dioxide was making its way up through 1,400 metres of rock.

“There is no evidence so far for escape of injected CO2 from depth,” the report said. It also found the area “highly suitable” for long-term carbon dioxide storage.

Centre director Malcolm Wilson said Lafleur’s report wasn’t enough on its own to conclude carbon dioxide is leaking. “I will never say that it couldn’t happen, but at the moment I think it’s very premature to make that linkage,” he said. “There are a lot of other potential sources of the CO2.”

He added, however, that Lafleur has raised some significant questions. “We do have to take into account some of the carbon isotope analysis.” Delfrari said the nearest injection well is about two kilometres from the Kerr property and no other farmers in the area have complained. “We’re confident that none of (the carbon dioxide) is making its way back to the Kerr property.”

She said the Kerrs have suggested that Cenovus buy them out. Lafleur said there’s no way the heavy concentrations of the gas he found could have been naturally generated. “Biogeneic gas is simply not the source of this tremendous amount of CO2, both from a volume point of view and from the isotope point of view. “All reservoirs leak. Every one of them.”

Lafleur emphasized that most of the carbon dioxide stays underground. But so much is injected that even small leaks can have health impacts. He said environmental monitoring of the Weyburn project virtually ceased in 2005. Carbon dioxide is not poisonous, but it does have health effects and can cause asphyxiation in heavy concentrations.

Saskatchewan Energy and Resource Minister Bill Boyd said his government is prepared to take another look at the situation, but said he wouldn’t order the project to stop or slow down. “We’re prepared to take a very serious look at this situation,” he said. “In the meantime, we feel that things are handled appropriately.”

Chris Severson-Baker from the Pembina Institute, an environmental think-tank, suggested there is a greater chance of leakage from projects that combine oil recovery with carbon storage. “We’re nervous and not supportive of enhanced oil recovery,” he said. “If you drill lots of wells into an oil formation, you’re going to have leaks.”

Such sites aren’t chosen because they’re good storage areas, said Severson-Baker, but because they’re under an oilfield that would benefit from injection. He said deep saline aquifers, such as those being explored in Alberta, are better choices. The suggestion that the Weyburn capture and storage project might be leaking could have implications far beyond one rural neighbourhood.

The Alberta government has committed $2 billion to similar pilot projects. The United States has committed $3.4 billion for carbon capture and storage. Norway has been injecting carbon dioxide into the sea floor since 1996. There are carbon capture and storage tests planned in Australia, Germany, Poland, the United Kingdom, China and Japan.

‘Ozone hole’ shenanigans were the warm-up act for ‘Global Warming’

By Joseph D’Aleo, CCM, AMS Fellow

Dr. Wil Happer of Princeton wrote “The Montreal Protocol to ban freons was the warm-up exercise for the IPCC.  Many current IPCC players gained fame then by stampeding the US Congress into supporting the Montreal Protocol. They learned to use dramatized, phony scientific claims like “ozone holes over Kennebunkport” (President Bush Sr’s seaside residence in New England). The ozone crusade also had business opportunities for firms like Dupont to market proprietary “ozone-friendly” refrigerants at much better prices than the conventional (and more easily used) freons that had long-since lost patent protection and were not a cheap commodity with little profit potential” (link).

Even James Lovelock agrees. James Lovelock formulated the Gaia hypothesis, which postulates that the biosphere is a self-regulating entity with the capacity to keep our planet healthy by controlling the chemical and physical environment. He later became concerned that global warming would upset the balance and leave only the arctic as habitable. He began to move off this position in 2007 suggesting that the Earth itself is in “no danger” because it would stabilize in a new state.

James Lovelock’s reaction to first reading about the leaked CRU emails in late 2009 was one of a true scientist. “I was utterly disgusted. My second thought was that it was inevitable. It was bound to happen. Science, not so very long ago, pre-1960s, was largely vocational. Back when I was young, I didn’t want to do anything else other than be a scientist. They’re not like that nowadays. They don’t give a damn. They go to these massive, mass-produced universities and churn them out. They say: “Science is a good career. You can get a job for life doing government work.” That’s no way to do science.

I have seen this happen before, of course. We should have been warned by the CFC/ozone affair because the corruption of science in that was so bad that something like 80% of the measurements being made during that time were either faked, or incompetently done.

Fudging the data in any way whatsoever is quite literally a sin against the holy ghost of science. I’m not religious, but I put it that way because I feel so strongly. It’s the one thing you do not ever do. You’ve got to have standards.”

On a March 2010 Guardian interview, Lovelock opined “The great climate science centres around the world are more than well aware how weak their science is. If you talk to them privately they’re scared stiff of the fact that they don’t really know what the clouds and the aerosols are doing...We do need skepticism about the predictions about what will happen to the climate in 50 years, or whatever. It’s almost naive, scientifically speaking, to think we can give relatively accurate predictions for future climate. There are so many unknowns that it’s wrong to do it.”

Will Happer further elaborated “The Montreal Protocol may not have been necessary to save the ozone, but it had limited economic damage. It has caused much more damage in the way it has corrupted science. It showed how quickly a scientist or activist can gain fame and fortune by purporting to save planet earth.  We have the same situation with CO2 now, but CO2 is completely natural, unlike freons. Planet earth is quite happy to have lots more CO2 than current values, as the geological record clearly shows.  If the jihad against CO2 succeeds, there will be enormous economic damage, and even worse consequences for human liberty at the hands of the successful jihadists.”

LIKE GLOBAL WARMING THE DATA DOESN’T SUPPORT THE THEORY

The ozone hole has not closed off after we banned CFCs. See this story in Nature about how the Consensus about the Ozone Hole and Man’s Role (with CFCs) May Be Falling Apart.

image
The size of the hole has hardly changed since 1990 (enlarged here).

“As the world marks 20 years since the introduction of the Montreal Protocol to protect the ozone layer, Nature has learned of experimental data that threaten to shatter established theories of ozone chemistry. If the data are right, scientists will have to rethink their understanding of how ozone holes are formed and how that relates to climate change. Markus Rex, an atmosphere scientist at the Alfred Wegener Institute of Polar and Marine Research in Potsdam, Germany, did a double-take when he saw new data for the break-down rate of a crucial molecule, dichlorine peroxide (Cl2O2). The rate of photolysis (light-activated splitting) of this molecule reported by chemists at NASA’s Jet Propulsion Laboratory in Pasadena, California1, was extremely low in the wavelengths available in the stratosphere - almost an order of magnitude lower than the currently accepted rate.

“This must have far-reaching consequences,” Rex says. “If the measurements are correct we can basically no longer say we understand how ozone holes come into being.” What effect the results have on projections of the speed or extent of ozone depletion remains unclear.

Other groups have yet to confirm the new photolysis rate, but the conundrum is already causing much debate and uncertainty in the ozone research community. “Our understanding of chloride chemistry has really been blown apart,” says John Crowley, an ozone researcher at the Max Planck Institute of Chemistry in Mainz, Germany. “Until recently everything looked like it fitted nicely,” agrees Neil Harris, an atmosphere scientist who heads the European Ozone Research Coordinating Unit at the University of Cambridge, UK. “Now suddenly it’s like a plank has been pulled out of a bridge.”

STILL COMING

Yet like the cultists whose spacecraft didn’t arrive on the announced date, the government scientists find ways to postpone it and save their reputations (examples “Increasing greenhouse gases could delay, or even postpone indefinitely the recovery of stratospheric ozone in some regions of the Earth, a Johns Hopkins earth scientist suggests” here and “Scientists Find Antarctic Ozone Hole to Recover Later than Expected” here

“The warmers are getting more and more like those traditional predictors of the end of the world who, when the event fails to happen on the due date, announce an error in their calculations and a new date.” Dr. John Brignell, Emeritus Engineering Professor at the University of Southampton, on Number Watch (May 1) PDF

THE UNITED KINGDOM

The Central England Temperature record is one of the longest continuous temperature record in the world extending back to the Little Ice age in 1659. December 2010 was the coldest December in 120 years with an average of -0.7C just short of the record of -0.8C recorded in December 1890 and the Second Coldest December Temperature in the entire record (352 years).

In addition to the cold, heavy snow hampered travel by air, rail and road.

In Ireland, this has been the coldest start to winter for the last 130 years, when general records began. According to Met Eireann, Ireland’s meteorological service, December has officially been the coldest month ever on record. County Mayo recorded low temperatures of -17.2C (1F).

Ireland’s Armagh Observatory has a longer period of record extending back to 1795. The Armagh mean monthly temperature was -0.3 degrees Celsius (31.4 degrees Fahrenheit), about 5.4 Celsius below average, making December 2010 the second coldest December in Armagh. The three coldest Decembers in Armagh are now those of 1878, 2010 and 1796, with average temperatures of -0.5 C, -0.3 C and 0.6 C respectively.

The maximum air temperature was 10.8 C on the 28th, whilst the lowest air temperature was -11.9 C on 21st, making the morning of the winter solstice the fourth coldest December night in Armagh since records of daily temperature maxima and minima began in August 1843. Previous cold December nights were -14.6 C on Christmas Day 1878, -13.7 C on Christmas Eve 1878, and -12.2 C on December 20th 1886. In 2010 there were twenty-four nights with grass frost and twenty-four with air frost, with snow falling on six days.

The winter solstice, December 21st, was also the coldest day since 1843, with a maximum temperature of -8.0 C and an average temperature of -10.0 C. This was probably the coldest day in Armagh since the very cold 13th January 1814, which with morning and evening temperatures of -12.2 C and -13.3 C reportedly had ‘the hardest frost recorded here for the space of 20 years’.

Probably the most notable record of the winter so far is the new all time record low for Northern Ireland, of -18.7C recorded on the 23rd of December at Castlederg, County Tyrone. In addition, all of the following weather stations recorded their all time record lows since recording began, this winter:

• RAF Leeming at -17.9C on the 3rd of December
• RAF Topcliffe at -19.0C on the 3rd of December
• Linton-on-Ouse at -17.3C on the 3rd of December
• Church Fenton at -17.5C on the 3rd of December
• RAF Scampton at -13.6C on the 3rd of December

NORTHEAST EUROPE

Germany has experienced the coldest December in more than 40 years, the German Weather Service (DWD) said. See report here.
The average temperature in December was 4.3 degrees below the past records on average, the DWD said. People have never seen such a freezing December since 1969.

The bitter cold was mainly stuck in the north and east of the country, where night temperatures in many places were below minus 20 degrees, the weather agency added. A DWD monitoring station near northeastern city of Postdam recorded only four days when the temperatures were above zero degree this month.

Snowfall was very heavy. Munich, Germany, recorded a snowfall total for December of 52 inches and the temperature averaged 6.3C below normal. 42 inches of snow was reported in Berlin. For the first time since 1981, all people in every place of the country celebrated “a white Christmas” together in this December.

In western Poland, the city of Poznan had a snowfall total of 58 inches. Poland temperatures were over 5C below normal.

SCANDINAVIA’S BRUTAL DECEMBER

According to the Swedish meteorological agency SMHI, several parts of Sweden, including the southern region Gotaland and eastern Svealand, experienced “the coldest December in at least 110 years.” Temperatures were as much 8C (15F) below normal.

As Norway entered its fifth week of bitterly cold weather over most of the country, Norwegians were being warned that their electricity bills in January may be three times as high as they were this past January, when cold weather also had sent rates soaring.

Cold weather has sent power demand up and supplies down, resulting in record high electricity rates. PHOTO: Views and News

The ongoing cold snap has left mountain reservoirs with the lowest water levels in 28 years. That’s bad news for a country that relies on hydroelectric power. Spot prices for power have risen from 40 ore per kilowatt hour in the Oslo area earlier this fall to 72 ore this week, with more increases looming. The situation is worse for residents of central Norway, where rates are even higher.

CHINA SNOW AND COLD

Days of continuous snowfall hit northwestern and eastern China, causing roadblocks and delays. Heavy snow fell in China’s northwest Xinjiang province after December 20 and accumulated to over one meter in some parts. The eastern province of Shandong has also been affected. Temperatures dropped to -25C in some areas, causing concern that China might see a repeat of the extreme weather of early 2008 that killed 129 people, left millions stranded and brought the country to a standstill during the Lunar New Year celebrations.

INDIA SHIVERS

Dr. Madhav Khandekar, a meteorologist from Canada vacationing in India writes: “Here in Vadodara , a western India city, early morning temp is at 7-8C and afternoon at 20C or so. It feels cold inside houses of most residents, especially poorly built houses of many and that is what makes a colder climate more dangerous now. It is time to write about ‘dangerous cold climate ahead!’ Delhi had a maximum of 15C on Sunday. And inside our apartment, the temperature dipped to 12C. Most Indian homes, do not have any heating facility as a result, we spend our time at home completely wrapped up in winter clothes.”

More than 100 people have died as a cold wave intensified its grip over northern and eastern parts of India, officials and news reports said Saturday.

The northern state of Uttar Pradesh, which has been the worst hit, has seen 22 new deaths since Wednesday, taking the death toll from a fortnight of cold weather to 63, according to figures released by the state government.

Most victims were either elderly or poor, with inadequate shelter and warm clothing, state officials said.

The town of Churk was the coldest place in Uttar Pradesh on Saturday, recording a low temperature of 1.4 degrees Celsius. Meanwhile, more deaths were also blamed on freezing temperatures in the eastern state of Jharkhand, increasing the death toll there to 62, the IANS news agency reported.

The capital New Delhi and the Himalayan states of Jammu and Kashmir and Himachal Pradesh have also experienced cold weather, leaving more than a dozen people dead there, according to local news channels.

Are huge northeast snow storms due to global warming?

By Dr. Richard Keen

The winter of 2009-2010 was a memorable one in the Northeast and Mid-Atlantic states, with locations like Philadelphia enjoying multiple massive snow storms that led to record totals for the winter.  As with all exceptional weather events of late, the usual suspects blamed the occurrence on global warming.  In a NOAA press release reported in USA Today, Jay Lawrimore stated that…

“Heavy snow, like the record snows that crippled Baltimore and Washington last winter, is likely to increase because storms are moving north.” To which I commented on “Watts Up With That” here on July 16, 2010 that Lawrimore’s remarks show a complete lack of understanding of weather (which makes up climate).

Anyone who spends a few winters on the East coast knows that snow there is generally caused by lows off the coast, and if the storms move north (as Lawrimore claimed), Baltimore, Philadelphia, NYC et al. find themselves in the warm sectors of the lows, and enjoy warm southerly winds and rain.

That’s the theory; how about some data to show that a warmer climate should lead to less snow, not more.  The data are easy to find and interpret.  More than a century of winter snow totals and average winter temperatures (December-January-February) are posted on the NWS Philadelphia web site. 

Seasonal snow totals in Philadelphia are dominated by the occurrence (or non-occurrence) of large snow events (i.e., the snowiest winters have two or three major storms, and the least snowy winters had none). Here are some charts and correlations.

image

Chart 1 (enlarged here) compares yearly winter snow totals (in blue) with winter mean temperatures (in red).  The small circles are for individual winters, and the heavy lines are 30-year running means (since climate is defined by some, such as the WMO, as a 30-year average).  The winter temperatures are plotted upside-down to show the correlation better.  And the correlation is that warm spells, like those in the 1930s, 1950s, and 1990s, have less snow overall than cold epochs like the 1900s, 1910s, 1960s, and 1970s. 

Note that the 30-year running means are plotted and the end of each 30-year period, so while the 30-year means are shifted a bit from the highs and lows of the annual values, the 30-year curves for snow and temperature line up together.  Also note that over 126 years, Philadelphia’s winters are not getting warmer or colder, and there’s not much change in snowfall.

image

Chart 2 (enlarged here) is a direct comparison of yearly snowfall with winter temperatures.  The correlation coefficient (square root of R2) is greater than -0.5, which is not bad for anything in climate.  It clearly shows a trend for more snow during colder winters, and less snow during mild winters.  Philadelphia’s average annual snow fall is 20.5 inches, and the coldest winters produce about twice that amount, while the warmest winters are almost snowless.

The occurrence of snowy and less snowy winters during cold and mild winters is summarized in the table below.  Although half of the winters are warmer than the median temperature (of course!) and half are colder, and half of the winters are snowier than median and half are less snowy, the co-occurrence of snow vs. temperature is not so even. 

image
Enlarged here.

There are several ways to describe the relation between winter temperature and snowfall…

Colder winters are three times more likely to be snowier than the median.

Snowy winters are three times more likely to be cold.

Warm winters are three times more likely to have less snow than the median.

Less snowy winters are three times more likely to be mild.

One way the relation between snowfall and winter temperature CANNOT be described is that warmth leads to more big snowstorms and greater total winter snowfall.

By the way, I did this analysis for Philadelphia because it’s where I was raised and learned about weather before moving to Colorado.  The warmers will no doubt raise their usual charge of “cherry-picking” when inconvenient data shows up.  I challenge them to examine others locations in the northeast to find one they can “cherry pick” to support their claims.  Until they do, the recent large snowstorms stand not as a symptom of global warming, but as yet another indication that global warming may not be happening at all.

Met Office knew big freeze was coming but hushed it up

Update: See James Delingpole’s How the Doomed Met Office tried to spin its way out of trouble here. See the GWPF story and letter “Did UK Government Keep Cold Winter Warning Secret In Run-Up To UN Climate Conference?” here.

-----------

By Rachel Quigley, UK Daily Mail

The Met Office warned ministers to expect an ‘exceptionally cold winter’ but then kept the prediction secret from the public. The forecaster decided not to reveal the information because it was embarrassed after wrongly predicting a ‘barbecue summer’ in 2009, BBC analyst Roger Harrabin said.

Instead of a seasonal forecast, it offered only monthly snapshots.

image
Cars try to make their way through the centre of York in the snow at the start of December.

The disclosure raises questions over whether transport authorities and councils could have been better prepared for the cold snap which brought chaos before Christmas.

As temperatures fell to a record low, train services were badly disrupted, roads were covered by snow and thousands were stranded at Heathrow as flights were cancelled and the airport struggled to clear the backlog.

Last night Mr Harrabin said: ‘With Britain shivering through a third winter in a row, shouldn’t the weather forecasters have warned us well in advance? Why didn’t the Met Office tell us?

‘The truth is it did suspect we were in for an exceptionally cold early winter, and told the Cabinet Office so in October. ‘But we weren’t let in on the secret because the Met Office no longer publishes its seasonal forecasts due to the ridicule it suffered for predicting a barbecue summer in 2009.

‘It did forecast in November that December would be bitter, but many of us may have taken the prediction with a truckload of salt.’ Last night the Met Office confirmed it had passed on the advice, but a spokesman denied that withholding it from the public was motivated by embarrassment.

‘We did brief the Cabinet Office in October on what we believed would be an exceptionally cold and long winter,’ she said. ‘Despite media claims to the contrary, the decision not to publish any more seasonal forecasts came after we undertook public research about the way in which we deliver the weather.

‘It was the public who decided that a monthly outlook would be more useful than a seasonal forecast to give a general indication of what the weather will be like for the following month.’ The Met office was widely criticised in 2009 for predicting a barbecue summer which turned out to be a washout. Mr Harrabin, who made his comments in the Radio Times, is one of the BBC’s most respected figures.

He has been reporting on the environment for more than 20 years and lectures at Oxford and Cambridge universities. His claims come after the forecaster was criticised for its advocacy of climate change.

Campaigners have claimed it has become too interested in calling for action to cut carbon emissions. They say it is in thrall to a belief that temperatures will rise in the long term, and so has neglected its focus on accurate short and medium term forecasts. The BBC announced last year that it was considering dropping the Met Office as its official forecaster after 87 years. But in July it decided to extend the contract for a further five years.

The Cabinet Office said that Met Office forecasts are shared ‘as appropriate’ but could not say if roads authorities, airports and water companies had been passed the explicit deep freeze alert. A spokesman said: ‘The Met Office provides the Government with regular updates throughout the year to inform short, medium and longer term planning. This information is shared as appropriate between departments and with local responders.

‘Government departments have, since winter 2009, continued to enhance preparedness and build resilience, informed by Met Office advice as well as the recommendations from David Quarmby’s review into last winter’s disruption and Dame Deirdre Hine’s review of the 2009 swine flu pandemic.’

No comment is really necessary. However, can you imagine if someone in private industry didn’t tell his clients what he or she truly thought and was as wrong as the UKMO has been. Back in 1996, I was part of a team that launched a cable Weather Network in the UK. The UKMO had decided it could commercialize some of its data - radar and METEOSAT satellite imagery. We bought radar and satellite from them. But during our weekend launch and the following Monday (a Bank Holiday), the radar and satllite link was not working. We finally reached them on Tuesday and were informed that a server was down and they were shocked we didn’t underestand it was a Bank Holiday weekend so they were not staffed. Again private industry operates 24x7 including holidays. BTW, The Weather Channel which had similar cable ambitions, bought our operations and merged it with theirs. But with the operations in expensive downtown London, operating costs were so high (10 times higher than our effort), they abandoned service within a year. Another in a long list of TWC fiascos.

That 97% Solution, Again

December 2010 Blizzard Timelapse from Michael Black on Vimeo.

Note: 32 inches fell.

UPDATE: Note an historic middle January period of extreme cold and snow appears likely for the United States and Eurasia. More to follow.

----------------

By Larry Solomon, The National Post

[SPPI Note: Also see the Dennis Ambler SPPI report.

How do we know there’s a scientific consensus on climate change? Pundits and the press tell us so. And how do the pundits and the press know? Until recently, they typically pointed to the number 2500 - that’s the number of scientists associated with the United Nations Intergovernmental Panel on Climate Change. Those 2500, the pundits and the press believed, had endorsed the IPCC position.

To their embarrassment, most of the pundits and press discovered that they were mistaken - those 2500 scientists hadn’t endorsed the IPCC’s conclusions, they had merely reviewed some part or other of the IPCC’s mammoth studies. To add to their embarrassment, many of those reviewers from within the IPCC establishment actually disagreed with the IPCC’s conclusions, sometimes vehemently.

The upshot? The punditry looked for and recently found an alternate number to tout - “97% of the world’s climate scientists” accept the consensus, articles in the Washington Post and elsewhere have begun to claim.

This number will prove a new embarrassment to the pundits and press who use it. The number stems from a 2009 online survey of 10,257 earth scientists, conducted by two researchers at the University of Illinois. The survey results must have deeply disappointed the researchers - in the end, they chose to highlight the views of a subgroup of just 77 scientists, 75 of whom thought humans contributed to climate change.  The ratio 75/77 produces the 97% figure that pundits now tout.

The two researchers started by altogether excluding from their survey the thousands of scientists most likely to think that the Sun, or planetary movements, might have something to do with climate on Earth - out were the solar scientists, space scientists, cosmologists, physicists, meteorologists and astronomers. That left the 10,257 scientists in disciplines like geology, oceanography, paleontology, and geochemistry that were somehow deemed more worthy of being included in the consensus. The two researchers also decided that scientific accomplishment should not be a factor in who could answer - those surveyed were determined by their place of employment (an academic or a governmental institution). Neither was academic qualification a factor - about 1,000 of those surveyed did not have a PhD, some didn’t even have a master’s diploma.

To encourage a high participation among these remaining disciplines, the two researchers decided on a quickie survey that would take less than two minutes to complete, and would be done online, saving the respondents the hassle of mailing a reply. Nevertheless, most didn’t consider the quickie survey worthy of response - just 3146, or 30.7%, answered the two questions on the survey:

1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?

2. Do you think human activity is a significant contributing factor in changing mean global temperatures?

The questions were actually non-questions. From my discussions with literally hundreds of skeptical scientists over the past few years, I know of none who claims that the planet hasn’t warmed since the 1700s, and almost none who think that humans haven’t contributed in some way to the recent warming - quite apart from carbon dioxide emissions, few would doubt that the creation of cities and the clearing of forests for agricultural lands have affected the climate. When pressed for a figure, global warming skeptics might say that human are responsible for 10% or 15% of the warming; some skeptics place the upper bound of man’s contribution at 35%. The skeptics only deny that humans played a dominant role in Earth’s warming.

Surprisingly, just 90% of those who responded to the first question believed that temperatures had risen - I would have expected a figure closer to 100%, since Earth was in the Little Ice Age in the centuries immediately preceding 1800. But perhaps some of the responders interpreted the question to include the past 1000 years, when Earth was in the Medieval Warm Period, generally thought to be warmer than today.

As for the second question, 82% of the earth scientists replied that that human activity had significantly contributed to the warming. Here the vagueness of the question comes into play. Since skeptics believe that human activity been a contributing factor, their answer would have turned on whether they consider a 10% or 15% or 35% increase to be a significant contributing factor. Some would, some wouldn’t.

In any case, the two researchers must have feared that an 82% figure would fall short of a convincing consensus - almost one in five wasn’t blaming humans for global warming - so they looked for subsets that would yield a higher percentage.  They found it - almost - in those whose recent published peer-reviewed research fell primarily in the climate change field. But the percentage still fell short of the researchers’ ideal. So they made another cut, allowing only the research conducted by those earth scientists who identified themselves as climate scientists.

Once all these cuts were made, 75 out of 77 scientists of unknown qualifications were left endorsing the global warming orthodoxy. The two researchers were then satisfied with their findings. Are you?

December cold - unprecedented?

Posted on WUWT, December 29, 2010 by Verity Jones

BBC news has reported that 40,000 homes are still without water in Northern Ireland after the recent spell of freezing temperatures. Many have been without water for more than 10 days, and reservoirs are being drained due to an unprecedented number of leaks since the thaw. Calls to a few friends confirmed that, yes, it is bad - friends in Lisburn have been without water since Christmas Eve due to a frozen mains supply (i.e. not in their house); others in Belfast report low water pressure. Water is being rationed in places.

Was it really that cold? A search of the BBC site revealed “‘Baltic’ Northern Ireland” tucked away on the BBC NI news page. Castlederg in the West of the province recorded a low of -18C on 20th December - a new record. The thing about Ireland is that it sits on the very western fringes of Europe, bathed by the warm Gulf Stream (which is why Doug Keenan considered the 7000 years of Irish tree ring data so important that he pursued Queen’s University through FOI requests). Ireland, despite its latitude, just doesn’t do ‘very cold’ (or ‘very hot’ for that matter).

When I first got interested in climate I ended up corresponding with Tonyb about the temperature records of the Armagh Observatory in Northern Ireland. These stretch back to 1796. How does this current cold month compare with the historical record at Armagh? Was the recent cold unprecedented?

The currently incomplete December record for Armagh consists of raw data - three automated readings per hour. Rather than waiting until they calculate the December average I looked for nearby stations on Weather Underground and found Glenanne PWS, about 15km to the SW of Armagh. The average temperatures for the two stations over the month of November is plotted in Figure 1. This gave a good linear fit (R^2 = 0.889) with an offset - Armagh being on average colder by just over 1C.

image
Figure 1. Average temperatures for Armagh and Glenanne N. Ireland through November 2010 (enlarged here).

Figure 2 shows the December data for Glenanne on the same scale. Up to the 28th December, the monthly average is -0.86C. Mild conditions are expected for the next three days and, if I plug the forecast max/min (29th 8/6; 30th 8/4; 31st 6/2) into my spreadsheet to complete the month, the monthly average rises to an estimated -0.23C for Glenanne, remembering that this is an approximation for Armagh, which is typically colder.

image
Figure 2. Average temperatures for Glenanne N. Ireland through December 2010 (enlarged here).

In the Armagh historical record, which I have for 1796-2002 from [1] the average temperature for December is 4.9C; January average is colder (4.1C). There are just two individual months colder than December 2010: January 1814 (-2.2C) and January 1881 (-0.9C) which puts this one as the third coldest on record at Armagh (2010 might yet tie with 1881 when the actual average for the month is published).

Coldest months according to the Armagh record:

1.January 1814 -2.2C
2.January 1881 -0.9C
3.December 2010 -0.2C
4.February 1855 0.0C, January 1963 0.0C
5.February 1895 0.2C
6.February 1947 0.4C
7.January 1985 0.5C, December 1878 0.5C

The list above also puts it in perspective with respect to other extreme years in living memory - most notably 1963 and 1947. According to the Armagh records none of the coldest months in these years saw such extreme cold as the Christmas period this year. The Arctic cold cut though the mild Atlantic air this year resulting in a monthly average 4-5C below normal (Figure 3).

image
Figure 3. Enlarged here.

Even without all the warming we have been led to expect wink December’s cold probably can be described as unprecedented. I’ll await with interest the actual December figures for Armagh (and those from the Met Office). As for this being caused by global warming - bull - it was just an extreme weather event. They happen. Go back >100 years and they happened then too.

UPDATE - from the Daily Mail (h/t Spectator in Tips & Notes).  Looks as if this will be a similar record in other parts of the UK too:

“Met Office figures show that the average temperature from December 1, the first day of winter, to December 28 was a bitter minus 0.8C (30.5F). This equals the record December low of 1890.”

The article goes on to point out that December is rarely the coldest month in the UK and a continued cold spell could beat the record set in 1683-84 of -1.17C.

2010 - where does it fit in the warmest year list?

By Dr. Don Easterbrook

1934 has long been considered the warmest year of the past century. A decade ago, the closest challenger appeared to be 1998, a super-el nino year, but it trailed 1934 by 0.54C (0.97F). Since then, NASA GISS has “adjusted” the U.S. data for 1934 downward and 1998 upward (see December 25, 2010 post by Ira Glickstein) in an attempt to make 1998 warmer than 1934 and seemingly erased the original rather large lead of 1934 over 1998. 

The last phases of the strong 2009-2010 El Nino in early 2010 made this year another possible contender for the warmest year of the century. However, December 2010 has been one of the coldest Decembers in a century in many parts of the world, so 2010 probably won’t be warmer than 1998.  But does it really matter?

Regardless of which year wins the temperature adjustment battle, how significant will that be? To answer that question, we need to look at a much longer time frame-centuries and millennia.

One of the best ways to look at long-term temperatures is with isotope data from the GISP2 Greenland ice core, from which temperatures for thousands of years can be determined.  The ice core isotope data were obtained by Minze Stuiver and Peter Grootes from nuclear accelerator measurements of thousands of oxygen isotope ratios (16O/18O), which are a measure of paleo-temperatures at the time snow fell that was later converted to glacial ice. The age of such temperatures can be accurately measured from annual layers of accumulation of rock debris marking each summer’s melting of ice and concentration of rock debris on the glacier.

The past century

Two episodes of global warming and two episodes of global cooling occurred during the past century:

image
Figure 1.  Two periods of global warming and two periods of global cooling since 1880. Enlarged here.

1880 to 1915 cool period.  Atmospheric temperature measurements, glacier fluctuations, and oxygen isotope data from Greenland ice cores all record a cool period from about 1880 to about 1915. Many cold temperature records in North America were set during this period. Glaciers advanced, some nearly to terminal positions reached during the Little Ice Age about 400 years ago. During this period, global temperatures were about 0.9C (1.6F) cooler than at present.  From 1880 to 1890, temperatures dropped 0.35C (0.6F) in only 10 years. The 1880-1915 cool period shows up well in the oxygen isotope curve of the Greenland Ice Sheet.

1915 to 1945 warm period

Global temperatures rose steadily in the 1920s, 1930s, and early 1940s. By the mid-1940s, global temperatures were about 0.5C (0.9F) warmer than they had been at the turn of the century. More high temperature records for the century were recorded in the 1930s than in any other decade of the 20th century. Glaciers during this warm period retreated, temperatures in the 1930s in Greenland were warmer than at present, and rates of warming were higher (warming 4C (7F) in two decades). All of this occurred before CO2 emissions began to soar after 1945, so at least half of the warming of the past century cannot have been caused by manmade CO2.

1945 to 1977 cool period

Global temperatures began to cool in the mid-1940’s at the point when CO2 emissions began to soar. Global temperatures in the Northern Hemisphere dropped about 0.5C (0.9F) from the mid-1940s until 1977 and temperatures globally cooled about 0.2C (0.4F). Many of the world’s glaciers advanced during this time and recovered a good deal of the ice lost during the 1915-1945 warm period. Many examples of glacial recession cited in the news media show contrasting terminal positions beginning with the maximum extent at the end of the 1880-1915 year cool period and ending with the minimum extent of the recent 20 year warm period (1977-1998).  A much better gauge of the effect of climate on glaciers would be to compare glacier terminal positions between the ends of successive cool periods or the ends of successive warm periods.

1977 to 1998 global warming

The global cooling that prevailed from ~1945 to 1977 ended abruptly in 1977 when the Pacific Ocean shifted from its cool mode to its warm mode in a single year and global temperatures began to rise, initiating two decades of global warming.  This sudden reversal of climate in 1977 has been called the
“Great Pacific Climate Shift” because it happened so abruptly. During this warm period, alpine glaciers retreated, Arctic sea ice diminished, melting of the Greenland Ice Sheet occur.

The abruptness of the shift in Pacific sea surface temperatures and corresponding change from global cooling to global warming in 1977 is highly significant and strongly suggests a cause-and-effect relationship.  The rise of atmospheric CO2, which accelerated after 1945 shows no sudden change that could account for the “Great Pacific Climate Shift”.

1999 to 2010 global cooling

No global warming has occurred above the 1998 level and temperatures have declined slightly. 

The past 500 years

Temperature oscillations recorded in Greenland ice cores over the past 500 years (Fig. 2) are truly remarkable. At least 40 periods of warming and cooling have occurred since 1480 AD, all well before CO2 emissions could have been a factor. 

image
Figure 2.  Warming and cooling periods from 1480 to 1960 AD. Enlarged here.

The past 5,000 years

Figure 3 shows oxygen isotope ratios from the GISP2 Greenland ice core for the past 5,000 years. Note that temperatures were significantly warmer than present from 1500 to 5000 years ago.

image
Figure 3. Oxygen isotope ratios for the past 5,000 years.  Red areas are warm periods, blue areas are cool periods. Enlarged here.

The past 10,000 years

Most of the past 10,000 have been warmer than the present. Figure 4 shows temperatures from the GISP2 Greenland ice core. With the exception of a brief warm period about 8,200 years ago, the entire period from 1,500 to 10,500 years ago was significantly warmer than present.

image
Figure 4.  Temperatures over the past 10,500 years recorded in the GISP2 Greenland ice core. (Modified from Cuffy and Clow, 1997)
Enlarged here.

Another graph of temperatures from the Greenland ice core for the past 10,000 years is shown in Figure 5. It shows essentially the same temperatures as Cuffy and Clow (1997) but with somewhat greater detail.  What both of these temperature curves show is that virtually all of the past 10,000 years has been warmer than the present.

image
Figure 5.  Temperatures over the past 10,000 years recorded in the GISP2 Greenland ice core. Enlarged here.

So where do the 1934/1998/2010 warm years rank in the long-term list of warm years? Of the past 10,500 years, 9,100 were warmer than 1934/1998/2010.  Thus, regardless of which year ( 1934, 1998, or 2010) turns out to be the warmest of the past century, that year will rank number 9,099 in the long-term list. The climate has been warming slowly since the Little Ice Age (Fig. 5), but it has quite a ways to go yet before reaching the temperature levels that persisted for nearly all of the past 10,500 years. It’s really much to do about nothing.  PDF

Headline 2000: “Snowfalls are now just a thing of the past”

By Marlo Lewis

On March 20, 2000, The Independent, a British newspaper, reported that “Snowfalls are just a thing of the past.” Global warming was simply making the UK too warm for heavy snowfalls. The column quotes Dr. David Viner of the Climatic Research Unit (CRU) of the University of East Anglia - yes, the epicenter of what would become the Climategate scandal - as saying that within a few years snowfall will become “a very rare and exciting event.” Indeed, Viner opined, “Children just aren’t going to know what snow is.”

Icecap Note: The Union of Confused Concerned Scientists said in 2004 Scientists claim winters becoming warmer and less snowy.

Similarly, David Parker, at the UK’s Hadley Centre for Climate Prediction and Research, said that eventually British children could have only “virtual” experience of snow via movies and the Internet.

Well, last week another British newspaper, the Daily Mail, reported ”The Coldest December since records began as temperatures plummet to minus 10C bringing travel chaos across Britain.” Here’s a snippet from the article (also excerpted by Wesley J. Smith in First Things):

Swathes of Britain skidded to a halt today as the big freeze returned - grounding flights, closing rail links and leaving traffic at a standstill. And tonight the nation was braced for another 10 in of snow and yet more sub-zero temperatures - with no let-up in the bitterly cold weather for at least a month, forecasters have warned. The Arctic conditions are set to last through the Christmas and New Year bank holidays and beyond and as temperatures plummeted to -10C (14F) the Met Office said this December was ‘almost certain’ to become the coldest since records began in 1910.

Meanwhile, back in the USA, the lead item in Google News is a Bloomberg story, “Snow Blankets US East Coast, Stranding Travelers.” Bloomberg reports that, “New York City’s Central Park had 20 inches (51 centimeters) of snow by 8 a.m., the most for the month in 62 years.” This was “the most snow in the park for any December since 1948, the agency’s website showed.” (Icecap Note: Over 30 inches fell in parts of New Jersey)

image

As in the UK, the record-breaking snowfall is disrupting transportation, keeping travelers snowbound and delaying Santa’s deliveries. It’s also downing power lines and turning off the Christmas lights. Some highlights:

“More than 6,000 flights were canceled in the region since yesterday as airports closed.”

“The day after Christmas is one of the five busiest shopping days of the year, and it may take retailers two weeks to capture sales lost yesterday,” an industry analyst told Bloomberg.

“NJ Transit, which transports about 170,000 commuters to and from New York City daily, suspended bus service as of 8:30 p.m. yesterday, according to a statement.”

“Four hundred subway passengers were aboard an A train that was stuck in Queens for more than six hours, until it could be pushed to a station by another train. The Coney Island area was without subway service.”

“Consolidated Edison Inc. reported there were 6,167 customers in Queens, New York, and 1,811 in Westchester County without power.”

“National Grid Plc, which provides electricity in New York and Massachusetts, was reporting power outages at 14 sites throughout New York and Massachusetts affecting about 29,727 homes and businesses. The largest was in Norfolk, Massachusetts, where 10,902 customers were without power.”

Hemispheric snowcover December 26, 2010 enlarged here.

As my colleague Heritage Foundation economist David Kreutzer observed at a panel discussion, winter is the biggest climate-related threat to public health and welfare!

Britain has had three snowy winters in a row, and this year’s Snowmageddon USA follows last year’s Snowpocalypse. Despite global warming, it seems, our children may never enjoy either Florida’s balmy weather in New York and Boston or Mediterranean “liveability” in the British isles. Post here.

See Bryan Walsh of Time magazine’s predictable annual alarmist story blaming the northeast snow on global warming. The ideologs are never wrong.

See also how Tucker Carlson Mocks Environmentalist For Believing Global Warming ‘Spaceship’ Theory here. In the debate Chris Horner and Carlson frustrate Betsy Rosenberg who tries to defend herself about the cold and snow being caused by global warming and claiming 97% of scientists agreed.

In actual fact, Dennis Ambler reported on that ‘survey’ on SPPI here. Ambler wrote “… they originally contacted 10,257 scientists, of whom 3,146 responded, less than a 31% response rate. Of that number, only 5% described themselves as climate scientists, numbering 157. The authors reduced that by half by only counting those who they classed as “specialists”.

“In our survey, the most specialized and knowledgeable respondents (with regard to climate change) are those who listed climate science as their area of expertise and who also have published more than 50% of their recent peer-reviewed papers on the subject of climate change (79 individuals in total). Of these specialists, 96.2% (76 of 79) answered “risen” to question 1 and 97.4% (75 of 77) answered yes to question 2.” So the world’s scientists boiled down to just a selection of 79 respondees. 

The survey questions:

1. When compared with pre-1800s levels, do you think that mean global temperatures have generally risen, fallen, or remained relatively constant?

This is quite banal and shows the desperation of those involved in this “unbiased survey of a large and broad group of Earth scientists.” Has it got warmer since pre-1800 levels? This really depends on the time period referred to. Do they mean the Little Ice Age, when disastrously cold temperatures caused massive loss of life and untold hardship? Of course temperatures are now warmer than that desperate period in climate history. Is that what they would wish to regard as normal?

2. Do you think human activity is a significant contributing factor in changing mean global temperatures?

This is the classic closed question, in that it implies mean global temperatures are being changed and someone must be responsible. The response to this question was 75 specialists out of 77, so here we have our massive 97%.

I WOULD ANSWER YES TO QUESTIONS 1 and 2. For question 1, we obviously are warmer than the Little Ice Age. The human activity in question 2 being some combination of UHI/land use changes and the manipulation by Hansen, Jones, Karl, etc.

Similarity to 2010/11 winter despite the flip from strong El Nino to strong La Nina

By Joseph D’Aleo, CCM

The warming NASA remarked about in the story below this fall in northeast Canada and Hudson Bay is part of the very strong negative arctic oscillation pattern we have seen the last few years, in part related to the long solar minimum and high latitude volcanoes.

Last winter saw the most negative AO of the record back to 1950. It persisted in the negative state from early December to the first day of spring.

The global anomalies with a negative winter AO are as follows:

See how well that verified this past winter. No GHGs need apply.

NOTE AMAZINGLY how even though we have replaced the strong El Nino with a strong La Nina, the result so far has been virtually the same for the start of the Northern Hemisphere winter. It is even colder in the southeast US, in Alaska and India. In the southern Hemisphere note the cold December to date in Australia and much of South America (the start of their summer). Summer snow even fell in southeast Australia.

The cross section through the polar region last year (above, enlarged here) showed the strong stratospheric warming favored in low solar east QBO (Quasi-biennial Oscillation) winters.

This year the QBO is west, which doesn’t favor stratospheric warmings but doesn’t prohibit polar warming in the troposphere (like we saw in 1995/96). This blocking then is more intermittent with blocks moving west being absorbed into the upstream mid latitude ridges and then reloading in the eastern Atlantic to Scandinavia and retrogressing westward. You can see that here in the cross section through the third week of December.

image
Enlarged here.

Note the AO is again off the charts (5 STD negative at times). It is forceast to diminish but then reload in a few weeks. Note also how the warmth is lower, at pressures above 100 mb compared to last year. To be effective in our weather it has to reach down to jet stream and middle troposphere - the case in both years.

At the end of blocking episodes when the blocks enter Canada, often there is a major nor’easter along the east coast as is forecast the next few days.  The storm that will become the nor’easter brought a rare white Christmas to parts of the southeast. In Europe, snow and cold continues to disrupt holiday travel by air, rail and road.

Arctic Oscillation spoiling NASA GISS party

By Joseph D’Aleo, CCM

In a recent post to counter the snow and cold in the news that was spoiling the announcement by Dr. Hansen that it was the warmest year on record, NASA GISS authors note for November:

“Northern Europe had negative anomalies of more than 4C, while the Hudson Bay region of Canada had monthly mean anomalies greater than +10C. The extreme warmth in Northeast Canada is undoubtedly related to the fact that Hudson Bay was practically ice free. It is for this reason that some of the largest positive temperature anomalies on the planet occur in the Arctic Ocean as sea ice area has decreased in recent years.

The cold anomaly in Northern Europe in November has continued and strengthened in the first half of December. Combined with the unusual cold winter of 2009-2010 in Northern Hemisphere mid-latitudes, this regional cold spell has caused widespread commentary that global warming has ended. That is hardly the case.”

See in this Steve Goddard post here how Hansen blamed the cooling in recent years on La Nina but now has decided this El Nino warming is global greenhouse warming.

Bob Tisdale has relevant posts on Watts Up With That that here shows how NASA GISS removed Arctic and Southern Ocean sea surface temperature data and then used 1200km smoothing that uses land stations to refill in the data (resulting in a warming) -note also shown by Steve Goddard here - and here how leftover warm ater from a strong El Nino gets spun up into the Kuroshio-Oyashio Extension (KOE) where it continues to release heat to help explain why the ‘global warmth’ has persisted into the early stages of the current La Nina.

Even Kevin Trenberth, head of climate analysis at the National Center for Atmospheric Research in Colorado, admitted here: “We have seen rapid warming recently, but it is an example of natural variation that is associated with changes in the Pacific rather than climate change.”

We have shown how NASA and the other data centers have mined the data for warmth and manipulated the data - new and old - to enhance the apparent warming. This includes a cooling (up to a quarter degree or more celsius) of the pesky warm period from the 1920s to 1950s right up to 1980. This includes the NASA GISS base period for anomalies of 1951 to 1980. Numerous data issues post 1980 have exaggerated the warmth.

The warming NASA remarked about this fall in northeast Canada and Hudson Bay is part of the very strong negative arctic oscillation pattern we have seen the last few years, in part related to the long solar minimum and high latitude volcanoes.

Enlarged here.

The positive AO state is characterized by an anomalously strong polar vortex that traps cold air in high latitude and more zonal mid-latitude jet stream that allows maritime Pacific air to invade North America and Atlantic air to flood Europe often as far east as the Urals. In the negative mode, high pressure dominates the polar region and North Atlantic, shunting arctic air south in North America and Siberian air west to Western Europe.

The greenhouse models all predict an increase in the frequency and strength of the positive arctic oscillation in time, most (2/3rds) exceeding the 90% range of natural variability.

A positive AO would lead to increasing temperatures in the Northern Hemisphere continents with colder than normal air trapped in the arctic down to the northern parts of Canada and Hudson Bay. The following from Mitchell shows the warmth over Eurasia in the positive AO phase.

Last winter saw the most negative AO of the record back to 1950. It persisted in the negative state from early December to the first day of spring.

The global anomalies with a negative winter AO are as follows:

As noted, the North Atlantic Oscillation, an important component of the overall arctic oscillation varies with the ocean temperature tripole in the Atlantic, known as the AMO or Atlantic Multidecadal Oscillation. When the Atlantic is in the warm positive AMO mode as is currently the case, the NAO and AO tend to be more negative.

image
Enlarged here.

When the AMO is positive with warm water in the North Atlantic and in the Tropical Atlantic, the NAO was mainly negative (1960s). When the North and Tropical Atlantic turned cold in the 1980s, the NAO was mainly positive (data in chart above through 1999). Note the AMO flipped positive (warm) in 1995 with a big dip in the NAO. See the inverse relationship with the AO in the graph below. Data for both is averaged for the December through March periods and standardized.

image
Enlarged here.

So far this late fall, the AO has been mainly negative and forecast by the model ensembles overnight to reach 5 standard deviations negative the next few days.

This explains not only the brutal cold in Europe and Asia but also the amazing 11F negative anomalies in the southeastern United States where they have had frosts and freezes for the fourth straight winter - including three La Ninas and one El Nino.

New Paper: Solar UV activity increased almost 50% over past 400 years

Merry Christmas!!! And during this joyous holiday, remember the true meaning and give thanks and praise.

image

Also appropriate see the RealCatholicTV.com’s “Global Warming Unmasked, the Real Agenda”. Are the environmental movements and groups simply devoted to laudable, correct stewardship of God’s creation, or do they have a more sinister, hidden agenda? Is “global warming” being used as an excuse for something far darker? Is the final goal of the liberal elites behind the push of junk science population control, eugenics and Gaia worship? See this hour long, well researched video here. You may have to purchase the DVD or sign up online to see the full presentation. Whatever your religion or whether or not you are religious, you can appreciate the effort done here, that very few in the mainstream media dare to undertake. Too often they simply are enablers for the enviros, corporate and government opportunists with a very sinister agenda or agendas.

HockeySchtick

A peer-reviewed paper published today in the Journal of Geophysical Research finds that reconstructions of total solar irradiance (TSI) show a significant increase since the Maunder minimum in the 1600’s during the Little Ice Age and shows further increases over the 19th and 20th centuries. The TSI is estimated to have increased 1.25 W/m2 since the Maunder minimum as shown in the first graph below. Use of the Stefan-Boltzmann equation indicates that a 1.25 W/m2 increase in solar activity could account for an approximate .44C global temperature increase [the HADCRU global warming from 1850 to 2000 is .55C].

A significant new finding is that portions of the more energetic ultraviolet region of the solar spectrum increased by almost 50% over the 400 years since the Maunder minimum (second graph below).  This is highly significant because the UV portion of the solar spectrum is the most important for heating of the oceans due to the greatest penetration beyond the surface and highest energy levels. Solar UV is capable of penetrating the ocean to depths of several meters to cause ocean heating. whereas long wave infrared emission from “greenhouse gases” or the sun is only capable of penetrating the ocean surface a few microns with all energy lost to the phase change of evaporation with no net heating of the ocean. Solar UV irradiance also “exerts control over chemical and physical processes in the Earth’s upper atmosphere” such as ozone levels.

Reconstruction of solar spectral irradiance since the Maunder minimum
By N. A. Krivova, L. E. A. Vieira, S. K. Solanki

Solar irradiance is the main external driver of the Earth’s climate. Whereas the total solar irradiance is the main source of energy input into the climate system, solar UV irradiance exerts control over chemical and physical processes in the Earth’s upper atmosphere. The time series of accurate irradiance measurements are, however, relatively short and limit the assessment of the solar contribution to the climate change. Here we reconstruct solar total and spectral irradiance in the range 115–160,000 nm since 1610.

The evolution of the solar photospheric magnetic flux, which is a central input to the model, is appraised from the historical record of the sunspot number using a simple but consistent physical model. The model predicts an increase of 1.25 W/m2, or about 0.09%, in the 11-year averaged solar total irradiance since the Maunder minimum. Also, irradiance in individual spectral intervals has generally increased during the past four centuries, the magnitude of the trend being higher toward shorter wavelengths. In particular, the 11-year averaged Ly-α irradiance has increased by almost 50%. An exception is the spectral interval between about 1500 and 2500 nm, where irradiance has slightly decreased (by about 0.02%). See post here.
