UAH Satellite Data for January 08 in Agreement with RSS Data

ICECAP UPDATE: NOAA agrees with the satellite assessment. The average United States temperature in January 2008 was 30.5 F. This was -0.3 F cooler than the 1901-2000 (20th century) average, the 49th coolest January in 114 years. This despite a very warm week 2 that brought hundreds of records to the central and east.

By Anthony Watts, Watts Up With That

University of Alabama, Huntsville (John Christy) just published their UAH lower troposphere data for January 2008. Like the RSS data set, it shows a negative anomaly, and a steep decline in the past 12 months though the magnitude of the anomaly is slightly lower at ∆T -.588 than the RSS ∆T -.629 degrees Centigrade.

I’ve plotted the UAH data below, as I did for the RSS data in the previous post:

Tornadoes Rip Through South in Typical La Nina Fashion

By Joseph D’Aleo, CCM

Yesterday was a busy day at the Storm Prediction Center and local forecast offices in the south. 68 tornaodes were reported with Tennessee and Arkansas hardest hit. CNN put the death toll at 52.

See full size image here.

About a month ago on Jan. 8, tornadoes were reported in Arkansas, Illinois, Missouri, Oklahoma and Wisconsin. Two died in the Missouri storms. Tornado outbreaks are more likely in La Nina years. A few years ago, I did a study of the years with the maximum number of tornadoes for every month and found that from the fall to the spring they were all La Nina years. The Superoutbreak of April 1974 came after one of the strongest La Ninas on record. And Eugenio Hackbart at the METSUL reminded me also in a similar La Nina in a cold Pacific era, in February 1971, more than 100 people died during an outbreak in the Mississippi Delta. This paper by Bove in 1999 supported this La Nina to severe weather outbreak connection.  An unpublished manuscript by Knowles and Pielke (1993) observed that tornadoes during ENSO cold phase (La Nina) are stronger and remain on the ground longer than their warm phase (El Nino) counterparts. They further showed that there is an increased chance of large tornado outbreaks (40 or more tornadoes associated with a single synoptic system) during ENSO cold phase (La Ninas). Given the strength of this La Nina, what it has been able to do in January and February and that history, we might expect a very stormy spring from the south to the Ohio Valley.  Predictably, someone (this case Senator Kerry) was bound to pronounce the tornadoes were the result of global warming. Fortunately the story had a Storm Prediction Center meteorologist Roger Edwards inject doubts about any global warming and tornado relationship.

In La Ninas, the cold tends to want to stay across the north and strong warmth builds at times across the south. Storms along the boundary feed on the contrast and severe weather often results. To the north of the storm track, it is ice or heavy snow that is the problem and that will be the story over the next few days. As we had indicated a few weeks ago, places like Des Moines, Chicago, Detroit would be first in line and then part of the northeast. With this series of the storms this week, Des Moines will end up with a foot of snow. Chicago’s forecast for today is for 12-14 inches over far northern suburbs rangind down to 8-10 in far southern suburbs (see Tom Skilling blog). For Detroit 6-10 inches is forecast with more to the north. In the northeast it is now snowing hard across the north with cold rain in the central areas in sharp contrast to unseasonable warmth to the south (it is actually above 70F in parts of Virginia and coastal Maryland into New Jersey). The rain across central New York State and New England will gradually transition to sleet and snow today and tonight. Thunderstorms will likely be in the cards further south until the cold air begins to filter back in and be reinforced this weekend with an arctic blast.  Wild swings as we said a few months back are also typical of La Nina.

Carbon Dioxide in Not the Primary Cause of Global Warming: The Future Can Not Cause the Past

Paper by Allan M.R. MacRae, Calgary Alberta Canada

Despite continuing increases in atmospheric CO2, no significant global warming occurred in the last decade, as confirmed by both Surface Temperature and satellite measurements in the Lower Troposphere. Contrary to IPCC fears of catastrophic anthropogenic global warming, Earth may now be entering another natural cooling trend. Earth Surface Temperature warmed approximately 0.7 degrees Celsius from ~1910 to ~1945, cooled ~0.4 C from ~1945 to ~1975, warmed ~0.6 C from ~1975 to 1997, and has not warmed significantly from 1997 to 2007.

CO2 emissions due to human activity rose gradually from the onset of the Industrial Revolution, reaching ~1 billion tonnes per year (expressed as carbon) by 1945, and then accelerated to ~9 billion tonnes per year by 2007. Since ~1945 when CO2 emissions accelerated, Earth experienced ~22 years of warming, and ~40 years of either cooling or absence of warming. 

The IPCC’s position that increased CO2 is the primary cause of global warming is not supported by the temperature data. In fact, strong evidence exists that disproves the IPCC’s scientific position. This UPDATED paper and Excel spreadsheet show that variations in atmospheric CO2 concentration lag (occur after) variations in Earth’s Surface Temperature by ~9 months. The IPCC states that increasing atmospheric CO2 is the primary cause of global warming - in effect, the IPCC states that the future is causing the past. The IPCC’s core scientific conclusion is illogical and false.

There is strong correlation among three parameters: Surface Temperature ("ST"), Lower Troposphere Temperature ("LT") and the rate of change with time of atmospheric CO2 ("dCO2/dt"). For the time period of this analysis, variations in ST lead (occur before) variations in both LT and dCO2/dt, by ~1 month. The integral of dCO2/dt is the atmospheric concentration of CO2 ("CO2").

ST and LT anomalies have been multiplied by 4 for visual clarity. See full size image here.

China and India Cold and Snow Blitz, Canada and United States Next?

By Joseph D’Aleo, CCM

Roger Pielke Sr. aptly notes Climate Science has made as one of its main conclusions that the needed focus for the study of climate change and variability is on the regional and local scales. Global and zonally-averaged climate metrics would only be important to the extent that they provide useful information on these space scales. The recent prolonged rare cold and snow in China provides an excellent example to support this conclusion. As reported on China View under the title Experts blame snow disaster on La Nina, atmospheric circulation

See the extent of the cold across much of China and India the 8 days ending February 2, 2008. Note amounts exceed 8 degrees Celsius (nearly 15 degrees F) in many locations. See a new story today on Planet Ark
China Battles “Coldest Winter in 100 Years”. Over 38% of the world’s population (2.4 billion) live in China and India.

Cold is again building in western Canada and will come east and south the next few weeks. Look for more snow and cold in the news in the weeks ahead across many areas of the northern United States. This too is classic La Nina, cold Pacific Decadal Oscillation weather. Snow fell heavily in the Pacific Northwest as we often find in La Ninas. In fact in some places in Oregon, heavy enough (eighteen inches on top of 6 feet of snow already there) to cause roofs to collapse. See Idahna, Oregon Buried in Snow; Mayor Asks for Emergency Help. This story has some amazing video.

As some of the cold air first makes an appearance across the northern tier the next few days, rain will change to snow with heavy amounts once again from Chicago across the Great lakes into New York State and New England. See Tom Skilling’s blog for stories on how Chicago already ranking as the 6th snowiest in 124 years of record is facing another heavy snow this week and is headed for a 60 inch plus snow season.

Severe Winter Storms Persist in China; Fuel and Food Are Short

See this story in the New York Times.  Millions of Chinese faced a humanitarian crisis on Friday as gasoline and food reserves dwindled and yet more bad weather was forecast for a country paralyzed by record-breaking cold and snow. More than 160 counties and cities in central China suffered blackouts and water shortages, the Xinhua news agency said, including Chenzhou, in Hunan Province, a city of four million that has been without power and water for more than a week. Stricken areas of south and central China are suffering the worst winter weather in half a century, with at least 60 people dead in weather-related accidents.

Hunan, Guizhou and Jiangxi were all facing fresh storms, and Mr. Zhu said the extreme weather could last another 10 days. Nearly six million passengers have been stranded on trains or in railroad stations in the past week. For millions of migrant workers, Lunar New Year is their only chance to see families all year.

Icecap Note: Our friends at the Metsul in Brazil remarked that this event is the “Chinese Katrina” in the sense of a social convulsion after a dramatic weather event. They also noted the Chinese news agency even published a webpage dedicated specially to this event.

We keep reading in these stories, that the cold or snow is the worst in 30 to 50 years. This may friends be because 30 to 50 years ago we were in the cold phase of the PDO and much of the time the warm phase of the AMO, which is currently the case. Recall I recently did a correlation of these factors at least with the US data (I had little faith in any of the global data bases except the satellite and it only goes back to 1979) and found a good correlation of US temperatures with the multidecadal cycles.

A Global Temperature History of the Past Two Millennia

By CO2 Science

CO2 Science reviewed the paper “A 2000-year global temperature reconstruction based on non-treering proxies” by Loehle in 2007 Energy and Environment Volume 18, pages 1049-1058.

Using data from eighteen 2000-year-long proxy temperature series from all around the world that were not developed from tree-ring data (which provide significant interpretive challenges), the author (1) smoothed the data in each series with a 30-year running mean, (2) converted the results thereby obtained to anomalies by subtracting the mean of each series from each member of that series, and then (3) derived the final mean temperature anomaly history defined by the eighteen data sets by a simple averaging of the individual anomaly series, a procedure that he rightfully emphasizes is “transparent and simple.” The results obtained by this procedure are depicted in the figure below, where it can be seen, in the words of its creator, that “the mean series shows the Medieval Warm Period (MWP) and Little Ice Age (LIA) quite clearly, with the MWP being approximately 0.3C warmer than 20th century values.”

See larger image here

Loehle notes that “the 1995-year reconstruction shown here does not match the famous hockey stick shape,” which clearly suggests that one of them is a poorer, and the other a better, representation of the truth. Because of its simplicity and transparency, as well as a host of other reasons described in detail by Loehle—plus what we have learned since initiating our Medieval Warm Period Record-of-the Week feature—it is our belief that Loehle’s curve is by far the superior of the two in terms of the degree to which it likely approximates the truth.

Snow, cold, in Saudi Arabia: “Worst in 30 Years”. Snow in Maui Too!

By Anthony Watts on Watts Up With That

According to wire reports, temperatures reached their lowest point in 30 years, reaching to -2C in the capital, Riyadh, and to -6C in mountainous regions blanketed by snow.  At least 10 people have died in the country as a weather system driven South from Siberia sent temperatures plummeting. Apparently its gotten so bad (or they just aren’t prepared to deal with it) that King Saud ordered that government assistance should be given in the affected areas, which witnessed sub-zero temperatures this week.


I had to laugh at the photo above and the caption:  Saudi Arabians are used to getting stuck in the sand, but snow is a new challenge for many. It almosts seems Pythonesque.

While I’m enjoying pointing out these uncommon phenomena, I’d also point out that even though both the northern and southern hemispheres have both seen some record cold events in the past 6 months, that doesn’t necessarily equate to “climate change”. Still, something seems afoot as we are seeing more and more events like this. Maybe the massive La Nina now stretching across the Pacific ocean has something to do with this.

Oh but wait, there’s more! Snow was seen yesterday atop Maui’s Mount Haleakala in Hawaii.


Yeah, somethings up.  See the full story and many more photos from the middle east and Hawaii on Anthony’s site here.

What a Front!

By Joseph D’Aleo, CCM

Late Thursday Update: See this story on the new snowstorm for the Midwest. The cold will abate early in February as we have been saying but expect a new arctic blast and snow even maybe further east early in week 2.

Late Wednesday Update: It dropped to 0F in Kirksville, MO this morning down from 55 yesterday. In St. Louis, the drop was from a high of 73F to 11F this morning.  Wind chills were as low as -57F in Grand Marais, MN. The front created chaos as it came east last night and today before losing its punch in the northeast. The next storm will lift northeast with heavy snows perhaps as far west as Chicago and St Louis and east as the eastern Great Lakes.

Tuesday’s Post:  An arctic front is whipping through the central states this morning with drops of 40 and 50 degress in the matter of hours. In Kirksville, MO at 7am when folks headed off to work and school, it was a balmy 55F.  By 1 pm as they were at lunch, it was a frigid 14F with 24 mph winds bringing a wind chill of -4F with light snow and blowing snow. At 2 pm it was down to 12F. The change is even more dramatic considering yesterday it reached 65F there. The low tonight is forecast to be 5F. Big drops like this were common throughout the plains and midwest and will be the case through tonight as the arctic front sweeps east.

See full size image here.

That cold front will put an end to the brief warm up as it sweeps east but the cold will moderate in transit. the readings well below zero in the upper midwest tonight will be much less severe as they come further east. Last week we talked about how the oscillating wave in the tropical high atmosphere called the MJO often affects the location of warming and cooling as it traverses the globe in an a somewhat erratic and irregular fashion. It is current roughly entering the same location where it was when the warmth was felt in the east and central earlier in January though this time the MJO is weaker so the warmth may not be as anomalous. This will likely mean above normal temperatures will dominate the next week to 10 days especially in the east with storms tending to curl west and bring rain and the warmest days. That track will mean the heaviest snows in places like Chicago and Detroit. After that, the cold should shift more to the east along with the threat again of snow for the east.

More Moisture in the Air?

By Karl Bohnak, Meteorologist

Water vapor accounts for about 95 percent of earth’s natural “greenhouse” effect. Carbon dioxide gets all the attention because that is what is released in the burning of fossil fuels. Yet it accounts for less than 4 percent of the total greenhouse effect. For the anthropogenic global warming argument to work, water vapor must increase along with CO2. C02’s contribution - natural and manmade - is just not enough to raise global temperatures as much as climate models predict. Two recent studies claim to show that moisture has indeed increased and go further in stating this increase is tied to human activity.

The latest edition of the Bulletin of the American Meteorological Society (BAMS) summarizes the findings of these papers in their “Nowcast” feature section. The first study, published in the Proceedings of the National Academy of Sciences, is titled “Identification of human-induced changes in atmospheric water content.” In it, an increase in atmospheric water vapor content was found. Then, a fingerprint examination of water vapor content in the atmosphere was conducted using computer models. The researchers claim to have found a “human fingerprint” on the increase, stating that other natural factors such as solar forcing or the atmosphere’s recovery from the eruption of Mt. Pinatubo in 1991 could not explain the increase. Roger Pielke, Sr., Senior Research Scientist at the Cooperative Institute for Research in Environmental Studies (CIRES) commented on this study at Climate Science: “The paper shows no trend in absolute humidity since 1998 despite surface temperature increasing since then! Indeed, plotting the model data since 1900 is disingenuous, since there is no data to compare with.” (Data from the satellite based Special Sensor Microwave Imager (SSM/I) was used, which is only available from 1988 on.)

The second paper was published in Nature and is entitled, “Attribution of observed surface humidity changes to human influence.” It states there has been a global increase of 2.2 percent in humidity in the years 1973-2002. The authors claim they found a “clear influence of manmade gases on increased humidity.” To this, Pielke commented: “The paper only deals with surface humidity (which as shown on Climate Science is very significantly altered by land use.)” In an email to ICECAP, he went further, stating that “model simulations are used to test the explanation. This is not the scientific method.”

On the other hand, Pielke coauthored a paper which does not support the findings of the above studies. In it, lower-tropospheric temperatures over North America had indeed increased between 1979 and 2006, but precipitable water vapor and total precipitable water content had not. This suggests that climate model assumptions of constant relative humidity in a warmer world may be all wet. See the pdf here.

When One Crazy Month Ends Up Normal

By Joseph D’Aleo, CCM

For Madison, Wisconsin, if the forecasts for the last three days of the month turn out close to accurate, January will average just about exactly normal. Someone years from now looking back at the month might assume it was a boring month. The folks who live there, where I spent 6 wonderful years at the University, will tell you it was anything but.

Take a look at the daily highs and lows for the month. The last three days are utilizing the local forecast office forecast values. After a frigid start, a ten day warm spell set in which peaked in week 2, held back by the snowpack that had built up from the second snowiest December on record and never entirely disappeared even during the warm days. Cold set back in on the 14th and really deepened after the 17th until the 25th. Moderation followed with today the 28th being the warmest day but it will be brief with another day blast of arctic air hitting hard late tomorrow into Wednesday when below zero readings return. 11 days of the month will have had below zero (F) readings, one day for an entire 24 hours. In contrast four days stayed entirely above freezing.

See full size table here

The city had 20.6 inches of snow as of this morning for the month following the second snowiest December which had 33.5 inches. The seasonal total with the 1.5 inches on November is 55.6 inches with two plus months more to go in the snow season. Normal total seasonal snow there is 44.1 inches, so already they have had a foot more than the normal amount of snow.

See full size map here

This confirms (1) how fickle and extreme La Ninas can be and (2) how they often produce above normal snows across the north central states. See pdf of this here.

Snow and Ice Update

By Joseph D’Aleo, CCM

With a major snowstorm in China and snow covering much of Asia and parts of the middle east and a decent snowpack in North America (recently NASA reported 60% of the lower 48 states and all of Canada was snowcovered), our Northern Hemispheric snowcover is now 2% above normal and the highest level in at least 5 years. A rather amazing 25% of the northern Hemispheric is snow and ice covered. The next two images come from Dr. Bob Hart at Florida State University. In the first, the green line represents the normal snowcover extent for the date and the blue the actual snowcover.

See full size image here.

In the second image the actual percent (black) is plotted relative to the climatological (green). We reversed a 2% snow and ice coverage deficit this past summer and now have a 2% excess (above normal).

See full size image here.

December sea ice extent in the Southern Hemisphere was a remarkable 15% above normal and the highest of the entire record as was the case in the late winter (it is now mid-summer and the sea ice is diminishing but is still well above normal). This graph is from the University of Illinois National snow and Ice data Center and shows the satellite derived sea ice extent in the southern hemisphere for Decembers since records began in 1979.

Stormy Period Ahead with Heavy Snows for Many Especially Central

By Joseph D’Aleo, CCM

A very stormy few weeks is in the cards as another regime change takes place. La Ninas are notoriously fickle unless they are super strong, We have a moderate La Nina ongoing and a fair amount of variability as I am sure you will agree from a very cold start in early December easing to more seasonable but very snowy conditions. A briefly bitter cold start to January gave way to a record second week warm spell. Frigid air returned in week 3 concentrated in the central states. It has moderated this weekend in the central and will by early week with some rains in the east but another shot of cold will be felt this week mainly across the north.

See full size image here

Intraseasonal variability can relate to episodes of high latitude blocking events (not a factor this year, at least not yet) and to a phenomenon known as the Madden Julian Oscillation; CPC has an excellent FAQ section here that answers questions about this phenomenon. The Australian Bureau of Meteorology tracks this phenomenon closely as it affects the probability and timing of rainfall events there. Tropical forecasters track it for timing enhanced tropical activity in summer and fall. Other forecasters look at it in winter to time stormy periods for the west and central United States and temperature fluctuations elsewhere.

We are entering a phase of the MJO that favors a series of storms for the west and central states that will bring very heavy snows to many areas there (focused mainly on the Midwest in areas like Des Moines, IA, Chicago IL and Madison, WI). You will see stories in the news about these snow events through the next few weeks. These storms will ride up through the northeast but those storm track usually mean rain for the east with the exception maybe in some events for the higher elevations up north and west (northern New York and northern Vermont). With time (in a few weeks) the storm track will shift east and assuming there are bullets left in storm gun, the east would get its shot at more snows, in time for ski areas to recover for the important President’s Day week.

Reanalysis of the Climate Factors with USHCN Version 2

By Joseph D’Aleo, CCM

A while ago, we presented correlations of US annual mean temperatures with carbon dioxide, solar irradiance, and ocean multidecadal cycles. We found the best correlations with the ocean cycles and irradiance and weakest with carbon dioxide, especially in the last decade.

NCDC has released its new climate data set Version 2 of USHCN in which it has replaced some of the prior adjustments (like Karl’s 1988 based urban adjustment) with an adjustment using an algorithm that is designed to find known and previously undocumented inhomogenteities (i.e. station moves, land use changes, etc.). The differences between the two data sets is relatively small but the pattern is hard to understand from a purely scientific basis. The biggest warming is post 2000 which has the effect of elevating recent years relative to the 1930s. It also warms the temperatures in the early 1900s which has the effect of diminishing the warming trend then.

The difference between version 1 and version 2 of NCDC USHCN Annual Mean Temperatures for the US. Full size image here.

I repeated the correlation analysis with the new data. Again the oceans came out on top followed by the solar irradiance.  The new data set had a higher correlation for CO2 for the entire record but when we look at the correlation of CO2 in the last decade it was actually even lower - a small negative.

Second Warmest Year Declaration Full of Pitfalls!

By Madhav Khandekar and Joseph D’Aleo

The news item about the year 2007 as the second warmest (Washington Post 12 January 2008) must be taken with a grain (maybe a whole block) of salt. Such declarations are based on calculating a mean temperature for the earth’s surface area (land-ocean combined) and this seemingly simple task is often full of ‘pitfalls’. Large areas of earth’s landmass were only sparsely monitored in the past, and remain so even today. Ironically the situation has gotten worse since 1990, when two thirds of the world’s climate reporting stations shut down. Add to that the issues of improper accounting for urbanization and land use changes as documented by Roger Pielke Sr. and most recently McKitrick and Michaels and poor siting as documented by Anthony Watts and his network of volunteers and unaccounted for instrument changes as Ben Herman blogged on Climate Science recently about, and you have a little reason to trust the accuracy of any station based data set.

Add to this the problem of calculating a mean temperature over the earth’s water bodies (oceans, lakes, rivers) and the task of calculating a mean temperature, accurate enough for declaring a certain year as “the warmest”, becomes even more challenging. Large ocean areas, especially in the Southern Hemisphere, remain unobserved even today, while over Northern Hemisphere, sea surface temperature data was available primarily over well-traveled ship tracks in the early 1900s and even today many ocean buoys and other temperature platforms are located in and around major shipping routes of the world oceans. And the methods for ship measurement of sea surface changed from canvas to wooden buckets in the 19th century and to ship intake in the World War II and later years, each of which produce different results. Although the changes occurred gradually, adjustments to the data were made arbitrarily in the late 1800s and in 1941. This too helps create uncertainty since the oceans are two thirds the globe. Climate Audit has had numerous posts on this ignored issue including this one.

So when NASA scientists James Hansen and colleagues declare 2007 to be the second warmest year, one has to wonder and ask: How good is their calculation? Is it possible to calculate the earth’s mean temperature accurate to a few tenth’s of a degree? How can NASA scientists then declare that the mean temperature for 2007 was 58.2F which was just 0.1F less warm than the year 1998? Further, NOAA calculated 2007 as the fifth warmest while the Climate Research Unit (CRU) in East Anglia (UK) which is the benchmark for IPCC (Intergovernmental Panel for Climate Change) calculated 2007 as the seventh warmest! So who one is right and who is wrong? Do we know for sure?

We do know, as Roger Pielke Jr. noted in a recent Prometheus blog, NASA’s (Hansen’s) assessment is warmest of all assessments and their forecast for future warming were greater than even the IPCC. He noted “Good scientific practice would have forecasting and data collection used to verify those forecasts conducted by completely separate groups.”

In reality, competing measures of station data and satellite derived data, show the earth’s mean temperature appear to have reached a plateau, which has been even been admitted by Rajendra Pachauri, the head of the U.N. IPPC that shared the 2007 Nobel Peace Prize with former U.S. Vice President Al Gore, saying “he would look into the apparent temperature plateau so far this century. One would really have to see on the basis of some analysis what this really represents” he told Reuters, adding “are there natural factors compensating? (for increases in greenhouse gases from human activities).  If the earth’s mean temperature is indeed steady while carbon dioxide has continued to rise, it is time to start to ask some hard questions about the global warming science.

Advocacy Out of Control in the Organizations and Media

By Joseph D’Aleo, CCM, AMS Fellow

As Andrew Revkin noted on the blog today, the American Geophysical Union, the world’s largest organization representing earth and space scientists, put out a fresh statement on the causes and consequences of recent climate change and possible responses. In the last few years, the Royal Society, the National Academy of Sciences (NAS) and the American Meteorological Society (AMS) have also issued statements endorsing the so-called “consensus” view that man is driving global warming.  What you don’t hear is that these societies never allowed member scientists to vote on these climate statements. Essentially, only two dozen or so members on ad hoc committees and governing boards of these institutions produced the “consensus” statements.

As a council member of one of the professional societies (the AMS), I can tell you I was extremely disappointed with the process and even the notion of the issuance of a statement supposedly representing the view of the society to policymakers without the full involvement of its members. In the case of the AMS, the statement drafting process involved appointing an ad hoc committee to draft a statement and then have the council review and recommend changes and then post for comment for just 30 days on the society web site home page. Few members frequent the home page often going to the site only to look for papers or register for upcoming conferences. Still the posted statement received a record number of comments back, many of them strongly negative. Despite an exhaustive effort to catalog the comments, in the end little substantive change was made to the statement.

Yet the society proclaimed to Dr. Roger Pielke Sr. when he inquired about the process for creating the statement that the committee simply ‘facilitated the drafting and that the council and the membership owned and controlled the final statement’. Roger pushed for longer review and for a referendum. When little changed from the draft statement and no changes were made to the process, Roger responded by posting the names of the authoring committee on Climate Science. Roger believes “this problem of our professional organizations using their positions as political pulpits is appalling and compromises the scientific process”.

And whatsmore, these societies and as Roger Pielke Sr. posted yesterday even organizations like UCAR have drifted away from objective science towards advocacy. Read much more here
