Alarmist Claim Rebuttal Overview

Below are a series of rebuttals of typical climate alarmists’ claims such as those made in the recently released Fourth National Climate Assessment Report.  The authors of these rebuttals are all recognized experts in the relevant scientific fields. The rebuttals demonstrate the falsity of EPA’s claims merely by citing the most credible empirical data on the topic. For each alarmist claim, a summary of the relevant rebuttal is provided along with a link to the full text of the rebuttal which includes the names and the credentials of the authors of each rebuttal.

Claim: Heat Waves are increasing at an alarming rate and heat kills.
Summary of Rebuttal

There has been no detectable long-term increase in heat waves in the United States or elsewhere in the world. Most all-time record highs here in the U.S. happened many years ago, long before mankind was using much fossil fuel. Thirty-eight states set their all-time record highs before 1960 (23 in the 1930s!).  Here in the United States, the number of 100F, 95F and 90F days per year has been steadily declining since the 1930s. The Environmental Protection Agency Heat Wave Index confirms the 1930s as the hottest decade. James Hansen while at NASA in 1999 said about the U.S. temperature record “In the U.S. the warmest decade was the 1930s and the warmest year was 1934”.  When NASA was challenged on the declining heat records in the U.S, the reply was that the U.S. is just 2% of the world.  However, all 8 continents recorded their all-time record highs before 1980. Interestingly while the media gives a great deal of coverage to even minor heat waves to support the case that man-made global warming is occurring, the media tends to ignore deadly cold waves. But in actual fact worldwide cold kills 20 times as many people as heat. This is documented in the “Excess Winter Mortality” which shows that the number of deaths in the 4 coldest winter months is much higher than the other 8 months of the year. The USA death rate in January and February is more than 1000 deaths per day greater than in it is July and August. Clearly, there is no problem with increased heat waves due to Climate Change.

Claim: Global warming is causing more hurricanes and stronger hurricanes.
Summary of Rebuttal

There has been no detectable long-term trend in the number and intensity of hurricane activity globally. The activity does vary year to year and over multidecadal periods as ocean cycles including El Nino/La Nina, multidecadal cycles in the Pacific (PDO) and Atlantic (AMO) favor some basins over others. The trend in landfalling storms in the United States has been flat to down since the 1850s. Before the active hurricane season in the United States in 2017, there had been a lull of 4324 days (almost 12 years) in major hurricane landfalls, the longest lull since the 1860s.
Harvey was the first hurricane to make landfall in Texas since Ike in 2008 and the first Category 4 hurricane in Texas since Hurricane Carla in 1961. There has been a downtrend in Texas of both hurricanes and major hurricanes. Texas is an area where Gulf Tropical Storms and hurricanes often stall for days, and 6 of the heaviest tropical rainfall events for the U.S. have occurred in Texas. Harvey’s rains were comparable to many of these events. Claudette in 1979 had an unofficial rainfall total greater than in Harvey. In Florida, where Irma hit as a category 4 on the Keys, it came after a record 4339 days (just short of 12 years) without a landfalling hurricane. The previous record lull was in the 1860s (8 years). There has been no trend in hurricane intensity or landfalling frequency since at least 1900.

Claim: Global warming is causing more and stronger tornadoes.
Summary of Rebuttal

Tornadoes are failing to follow “global warming” predictions. Big tornadoes have seen a decline in frequency since the 1950s. The years 2012, 2013, 2014, 2015 and 2016 all saw below average to near record low tornado counts in the U.S. since records began in 1954.  2017 rebounded only to the long-term mean.  This lull followed a very active and deadly strong La Nina of 2010/11, which like the strong La Nina of 1973/74 produced record setting and very deadly outbreaks of tornadoes. Population growth and expansion outside urban areas have exposed more people to the tornadoes that once roamed through open fields. Tornado detection has improved with the addition of NEXRAD, the growth of the trained spotter networks, storm chasers armed with cellular data and imagery and the proliferation of cell phone cameras and social media. This shows up most in the weak EF0 tornado count but for storms from moderate EF1 to strong EF 3+ intensity, the trend has been flat to down despite improved detection.

Claim: Global warming is increasing the magnitude and frequency of droughts and floods.

Summary of Rebuttal

Our use of fossil fuels to power our civilization is not causing droughts or floods. NOAA found there is no evidence that floods and droughts are increasing because of climate change. The number, extend or severity of these events does increase dramatically for a brief period of years at some locations from time to time but then conditions return to more normal. This is simply the long-established constant variation of weather resulting from a confluence of natural factors.  In testimony before Congress Professor Roger Pielke, Jr. said: “It is misleading, and just plain incorrect, to claim that disasters associated with hurricanes, tornadoes, floods, or droughts have increased on climate timescales either in the United States or globally. Droughts have, for the most part, become shorter, less frequent, and cover a smaller portion of the U.S. over the last century.” “The good news is U.S. flood damage is sharply down over 70 years,” Roger Pielke Jr. said. “Remember, disasters can happen any time....”. But it is also good to understand long-term trends based on data, not hype.”

Claim: Global Warming has increased U.S. Wildfires.

Summary of Rebuttal

Wildfires are in the news almost every late summer and fall.  The National Interagency Fire Center has recorded the number of fires and acreage affected since 1985. This data show the number of fires trending down slightly, though the acreage burned had increased before leveling off over the last 20 years. The NWS tracks the number of days where conditions are conducive to wildfires when they issue red-flag warnings. It is little changed. 2017 was an active fire year in the U.S. but my no means a record. The U.S. had 64,610 fires, the 7th most since in 11 years and the most since 2012.  The 9,574, 533 acres burned was the 4th most in 11 years and most since 2015. The fires burned in the Northwest including Montana with a very dry summer then the action shifted south seasonally with the seasonal start of the wind events like Diablo in northern California and Santa Ana to the south. Fires spread to northern California in October with an episode of the dry Diablo wind that blows from the east and then in December as strong and persistent Santa Ana winds and dry air triggered a round of large fires in Ventura County. According to the California Department of Forestry and Fire Protection the 2017 California wildfire season was the most destructive one on record with a total of 8,987 fires that burned 1,241,158 acres. It included five of the 20 most destructive wildland-urban interface fires in the state’s history. When it comes to considering the number of deaths and structures destroyed, the seven-fold increase in population in California from 1930 to 2017 must be noted. Not only does this increase in population mean more people and home structures in the path of fires, but it also means more fires.  Lightning and campfires caused most historic fires; today most are the result of power lines igniting trees.  The power lines have increased proportionately with the population, so it can be reasoned that most of the damage from wild fires in California is a result of increased population not Global Warming. The increased danger is also greatly aggravated by poor government forest management choices.

Claim: Global warming is causing snow to disappear.
Summary of Rebuttal

This is one claim that has been repeated for decades even as nature showed very much the opposite trend with unprecedented snows even to the big coastal cities. Every time they repeated the claim, it seems nature upped the ante more. Alarmists have eventually evolved to crediting warming with producing greater snowfall, because of increased moisture but the snow events in recent years have usually occurred in colder winters with high snow water equivalent ratios in frigid arctic air. Snowcover in the Northern Hemisphere, North America and Eurasia has been increasing since the 1960s in the fall and winter but declining in the spring. However, as NOAA advised might be the case, snowcover measurement methodology changes at the turn of this century may be responsible for part of the warm season differences.

Claim: Global warming is resulting in rising sea levels as seen in both tide gauge and satellite technology.
Summary of Rebuttal

This claim is demonstrably false.  It really hinges on this statement: “Tide gauges and satellites agree with the model projections.” The models project a rapid acceleration of sea level rise over the next 30 to 70 years.  However, while the models may project acceleration, the tide gauges clearly do not. All data from tide gauges in areas where land is not rising or sinking show instead a steady linear and unchanging sea level rate of rise from 4 up to 6 inches/century, with variations due to gravitational factors.  It is true that where the land is sinking as it is in the Tidewater area of Virginia and the Mississippi Delta region, sea levels will appear to rise faster but no changes in CO2 production would change that. The implication that measured, validated, and verified Tide Gauge data support this conclusion remains simply false.  All such references rely on “semi-empirical” information, which merges, concatenates, combines, and joins, actual tide gauge data with various models of the reference author’s choosing.  Nowhere on this planet can a tide gauge be found, that shows even half of the claimed 3.3 mm Sea level rise rate in “Tectonically Inert” coastal zones.  These are areas that lie between regions of geological uplift and subsidence.  They are essentially neutral with respect to vertical land motion, and tide gauges located therein show between 1 mm/yr (3.9 inches/century) and 1.5 mm/yr (6 inches/century rise). The great Swedish Oceanographer, Nils-Axel Morner, has commented on this extensively, and his latest papers confirm this ‘inconvenient truth. Further, alarmist claims that “Satellites agree with the model projection” are false. Satellite technology was introduced to provide more objective measurement of the sea level rise because properly adjusted tide gauge data was not fitting Alarmists’ claims.  However, the new satellite and radar altimeter data lacked the resolution to accurately measure sea levels down to the mm level. Moreover, the raw data from this technology also conflicted with Alarmists’ claims. As a result, adjustments to this data were also made - most notably a Glacial Isostatic Adjustment (GIA). GIA assumes that basically all land is rebounding from long ago glaciations and oceanic basins are deepening. The assumption is that this rebounding is masking the true sea level rise. Alarmists continue to proclaim that their models project a rapid acceleration of sea level rise over the next 30 to 70 years, when those same models have failed to even come close to accurately measuring the past 25 years.

Claim:  Arctic, Antarctic and Greenland ice loss is accelerating due to global warming.
Summary of Rebuttal

Satellite and surface temperature records and sea surface temperatures show that both the East Antarctic Ice Sheet and the West Antarctic Ice Sheet are cooling, not warming and glacial ice is increasing, not melting. Satellite and surface temperature measurements of the southern polar area show no warming over the past 37 years. Growth of the Antarctic ice sheets means sea level rise is not being caused by melting of polar ice and, in fact, is slightly lowering the rate of rise. Satellite Antarctic temperature records show 0.02C/decade cooling since 1979. The Southern Ocean around Antarctica has been getting sharply colder since 2006. Antarctic sea ice is increasing, reaching all-time highs. Surface temperatures at 13 stations show the Antarctic Peninsula has been sharply cooling since 2000. The Arctic includes the Arctic Ocean, Greenland, Iceland, and part of Siberia and northern Alaska. Because of the absence of any land mass in the Arctic Ocean, most of area lacks glaciers, which require a land mass. Thus, most of the Arctic contains only floating sea ice. Greenland, Iceland, northern Alaska, and northern Siberia contain the only glaciers in the general Arctic region. Arctic temperature records show that the 1920s and 1930s were warmer than 2000. Records of historic fluctuations of Arctic sea ice go back only to the first satellite images in 1979. That happens to coincide with the end of the 1945-1977 global cold period and the maximum extent of Arctic sea ice. During the warm period from 1978 until recently, the extent of sea ice has diminished, but increased in the past several years. The Greenland ice sheet has also grown recently.

Claim: Rising atmospheric CO2 concentrations are causing ocean acidification, which is catastrophically harming marine life.
Summary of Rebuttal

As the airs CO2 content rises in response to ever-increasing anthropogenic CO2 emissions, more and more carbon dioxide is expected to dissolve into the surface waters of the world’s oceans, which dissolution is projected to cause a 0.3 to 0.7 pH unit decline in the planet’s oceanic waters by the year 2300. A potential pH reduction of this magnitude has provoked concern and led to predictions that, if it occurs, marine life will be severely harmed - with some species potentially driven to extinction - as they experience negative impacts in growth, development, fertility and survival. This ocean acidification hypothesis, as it has come to be known, has gained great momentum in recent years, because it offers a second independent reason to regulate fossil fuel emissions in addition to that provided by concerns over traditional global warming. For even if the models are proven to be wrong with respect to their predictions of atmospheric warming, extreme weather, glacial melt, sea level rise, or any other attendant catastrophe, those who seek to regulate and reduce CO2 emissions have a fall-back position, claiming that no matter what happens to the climate, the nations of the Earth must reduce their greenhouse gas emissions because of projected direct negative impacts on marine organisms via ocean acidification.The ocean chemistry aspect of the ocean acidification hypothesis is rather straightforward, but it is not as solid as it is often claimed to be. For one thing, the work of a number of respected scientists suggests that the drop in oceanic pH will not be nearly as great as the IPCC and others predict. And, as with all phenomena involving living organisms, the introduction of life into the analysis greatly complicates things. When a number of interrelated biological phenomena are considered, it becomes much more difficult, if not impossible, to draw such sweeping negative conclusions about the reaction of marine organisms to ocean acidification. Quite to the contrary, when life is considered, ocean acidification is often found to be a non-problem, or even a benefit. And in this regard, numerous scientific studies have demonstrated the robustness of multiple marine plant and animal species to ocean acidification - when they are properly performed under realistic experimental conditions.

Claim: Carbon pollution is a health hazard.
Summary of Rebuttal

The term “carbon pollution” is a deliberate, ambiguous, disingenuous term, designed to mislead people into thinking carbon dioxide is pollution. It is used by the environmentalists to confuse the environmental impacts of CO2 emissions with the impact of the emissions of unwanted waste products of combustion. The burning of carbon-based fuels (fossil fuels - coal, oil, natural gas - and biofuels and biomass) converts the carbon in the fuels to carbon dioxide (CO2), which is an odorless invisible gas that is plant food and it is essential to life on the planet. Because the burning of the fuel is never 100% efficient, trace amounts of pollutants including unburnt carbon are produced in the form of fine particulates (soot), hydrocarbon gases and carbon monoxide.  In addition, trace amounts of sulfur oxides, nitrogen oxides and other pollutant constituents can be produced.  In the US, all mobile and industrial stationary combustion sources must have emission control systems that remove the particulates and gaseous pollutants so that the emissions are in compliance with EPA’s emission standards.  The ambient air pollutant concentrations have been decreasing for decades and are going to keep decreasing for the foreseeable future because of existing non-GHG-related regulations.
Detailed Rebuttal and Authors: EF_RRT_AC - Health


The well-documented invalidation of the “three lines of evidence” upon which EPA attributes global warming to human-caused CO2 emissions breaks the causal link between such emissions and global warming. {See here and here). 

This in turn necessarily breaks the causal chain between CO2 emissions and the alleged knock-on effects of global warming, such as loss of Arctic ice, increased sea level, and increased heat waves, floods, droughts, hurricanes, tornadoes, etc. These alleged downstream effects are constantly cited to whip up alarm and create demands for ever tighter CO2 regulation. EPA explicitly relied on predicted increases in such events to justify the Endangerment Finding. But as shown above, there is no evidence to support such claims, and copious empirical evidence that refutes them. The enormous cost and essentially limitless scope of the government’s regulatory authority over GHG/CO2 emissions cannot lawfully rest upon a collection of scary stories that are conclusively disproven by readily available empirical data.The legal criteria for reconsidering the Endangerment Finding are clearly present in this case. The scientific foundation of the Endangerment Finding has been invalidated. The parade of horrible calamities that the Endangerment Finding predicts and that a vast program of regulation seeks to prevent have been comprehensively and conclusively refuted by empirical data. The Petition for Reconsideration should be granted.

US Blizzards, Snowfalls Have Increased Since 1950s, Surprising Global Warming Climatologists

By P Gosselin on 20. February 2018

On January 4 NTZ weekly contributor Kenneth Richard published a list of 485 papers dumping cold water on climate alarmism in 2017.

Looking through the list I find published papers showing that snowfall frequency has in fact increased over the the past 60 years!

Blizzard activity jumps fourfold

For example a paper by Coleman and Schwartz, 2017 revealed 713 blizzards over the 55 years with 57 federal disaster declarations resulting. Of these 57 declared disasters, more than a half have occurred since the year 2000.

The published scientific study also founds that “seasonal blizzard frequencies displayed a distinct upward trend, with a more substantial rise over the past two decades”.


It adds that the modeled increase in blizzard activity showed a “nearly fourfold upsurge between the start and end of the study period at 5.9 and 21.6 blizzards, respectively”. If the trend continues, then we would need to expect even more such blizzards.

In a another publication, Changnon, 2017 evaluated heavy 30-day snowfall amounts east of the Rockies in the United States during the period 1900-2016. The comprehensive data assessment identified 507 stations in this long-term climate study.


The author examined the top 30-day heavy snowfall amount and the average of the top five 30-day heavy snowfall amounts. The findings also surprised global warming scientists who warned earlier that snowfall would become less frequent as the globe warmed. The publications abstract reads:

The northern Great Plains, Great Lakes, Midwest, and Northeast experienced more top five periods [more snow] in the second half of the 117-year period [1958-2016], where most of the southern states experienced top five periods throughout the study period.”

Finally a study conducted by Hatchett et al., 2017 found a “winter snow level rise in the northern Sierra Nevada from 2008 to 2017”. Sea surface temperatures offshore California were observed to be related to snow cover.




I’d like a reference of who exactly was surprised by this. Is that available?  A cold location would of course receive more snow with increasing humidity despite increasing temperatures. That seems to be pretty straight forward, doesn’t it? A location that barely reaches temperatures low enough for snow (let’s say, has only a few days of snow per year), would stop experiencing snow with increasing temperatures. That seems pretty straight forward too. So who was surprised?

Kenneth Richard Reply

IPCC TAR (2001):  “Milder winter temperatures will decrease heavy snowstorms”

Kunkel et al., 2002:  “Surface conditions favorable for heavy lake-effect snow decreased in frequency by 50% and 90% for the HadCM2 and CGCM1 [models], respectively, by the late 21st Century. This reduction [according to models] was due almost entirely to… an increase in average winter air temperatures.”

IPCC AR4 (2007):  “Snow season length and snow depth are very likely to decrease in most of North America”

Kapnick and Delworth, 2013:  “In response to idealized radiative forcing changes, both models produce similar global-scale responses in which global-mean temperature and total precipitation increase while snowfall decreases… By using a simple multivariate model, temperature is shown to drive these trends by decreasing snowfall almost everywhere” (press release) “In North America, the greatest reductions in snowfall will occur along the northeast coast, in the mountainous west, and in the Pacific Northwest. Coastal regions from Virginia to Maine…

The oceanographer Nils-Axel Morner challenges the IPCC and warnings about sinking islands

Basler Zeitung

Mr. Morner, you have recently visited the Fiji islands in South Pacific several times in order to research changes on the coasts and sea levels. Why Fiji?

Nils-Axel Morner: I knew there would be a science conference in New York in June 2017 that focused on sea level changes in Fiji. In addition, it was known that the island nation would chair the 23rd World Climate Conference, which took place last November in Bonn. Thus, Fiji moved into the focus of interest. It was said that the rising sea level had done a lot of damage there. I wanted to check with my own eyes if that is true.

What made you skeptical?

I have been researching sea-level changes my entire life, traveling to 59 countries. Hardly any other researcher has so much experience in this field. However, the IPCC has always misrepresented the facts on this topic. It exaggerates the risks of a sea level rise enormously. The IPCC relies in particular on questionable computer models rather than field research. However, I always want to know what is going on. That is why I went to Fiji.

However, according to ProClim, the Swiss climate research platform, there are a series of measurements in Fiji that show a sharp rise in sea level in recent decades. Specifically, the sea level has increased by 5.4 millimeters annually since 1990, which is twice as much as the global average.

Yes, I know these measurements. These are two series of tide heights, that is, water levels at low tide and high tide. We checked these data with the result that they are of very poor quality. One series has been influenced by the fact that port facilities were built on loose sediment soil near the measuring station, which could have changed tidal heights. For the other series, the measuring station was even moved. The researchers who rely on such data are office workers. They are not specialized in coastal dynamics processes and sea level changes. Many of them have no idea of ​​the real conditions.

How did you go about getting better data?

On the one hand, we have been following the given examples, where sea level rise is said to have led to coastal erosion. The result was that erosion has been caused by human intervention - such as new coastal structures altering water currents or increased harvests of sea cucumbers, which could have destabilized the seabed. To prove sea level changes over the past 500 years, we have dated sand deposits to see when they came into being. In addition, we have researched the spread of coral in recent centuries. Typically, coral reefs grow in height when sea levels rise and in width when they remain constant. If the level drops, corals die off. Corals do not lie; they are a reliable indicator - much more reliable than tidal measurements.

What was the result?

We were able to prove that the sea level in Fiji from 1550 to about 1700 was about seventy centimeters higher than it is today. Then it sank and was about fifty centimeters lower in the 18th century than it is today. Then it rose to about the current level. In the last 200 years, the level has not changed significantly. For the past 50 to 70 years, it has been stable.

Were you surprised?

Not really. It was not the first time that the claims of the IPCC turned out to be wrong.

Fiji is only a single archipelago. Maybe the situation is different in other places.

There are also data from many other places in the world. These by no means confirm the picture that the IPCC draws. In some places, the sea level is indeed rising, but in other places, it is stable, and elsewhere it is even dropping. For example, sea levels are constant in the Indian Ocean and on the Atlantic coast of South America. On South Pacific islands such as Tuvalu and Kiribati measurements do not confirm the constant warnings about the sinking of these archipelagos. The sea certainly erodes the shores here and there, but islands grow elsewhere as well. It has always been like this.

Why do many climate researchers warn then about sinking islands?

Because they have a political agenda. They are biased towards the interpretation that man is causing climate change, and that it is a threat. The IPCC was founded with the purpose of prove man-made climate change and to warn against it. His goal was thus fixed from the beginning. It sticks to it like a dogma - no matter what the facts are. As a specialist in sea level developments, I have consistently found in recent years that the IPCC team does not include a single expert on this issue.

Is there no problem with the rise of the sea level at all?


No danger that islands could sink?

The doomsday scenarios usually refer to the year 2100. I estimate that the sea level will then rise by five centimeters on average, with an uncertainty of 15 centimeters. The change might go from plus 20 centimeters to minus 10 centimeters. This is not a threat. Anyone who claims that there will be a threat of an increase of one meter or so has no idea of ​​physics.

However, a lot of meltwater from glaciers and ice shields flows into the sea.

Much less than you think. In Antarctica, no ice melts in total. When ice melts in the Arctic, it does not change the sea level - because floating ice does not affect the water level when melting according to the laws of physics. In essence, only melting ice on Greenland contributes to a level increase. However, this amount is small.

Seawater heats up and expands, increasing sea level.

That is true, but only by a few centimeters, not by decimeters or even meters. There are much more important influences, which affect the sea level, especially solar activity. There are also significant horizontal water shifts, from one ocean to another. Like the data in Fiji, those of the Maldives also show that levels were clearly higher in the 17th century than they are today. Significantly, this was the time when it was cold on the northern hemisphere; this period is called the Little Ice Age. At that time solar activity was lower than today. It was the big solar minimum. It seems that low solar activity is associated with high sea levels in the tropics - and vice versa. The sea levels seem to depend mainly on the oscillation of solar cycles and hardly on melting ice.

You are among the most distinguished critics of the IPCC. Why have you distanced yourself from the warnings of manmade climate change?

In 1991, I gave a scientific presentation at a conference on sea level changes in the U.S. The representative of the IPCC present there responded with great anger to my point of view. This reaction surprised me. Because in science circles, it is usual that you listen to each other and debate about different points of view. Later, I noticed more and more that the IPCC was disseminating false information and adhered to obvious mistakes. I then published a paper on the influence of the sun on the sea level, which was supported by 19 recognized experts. However, the IPCC attacked the paper with outrageous claims and caused the scientific journal, in which it was published, to be discontinued.

So do they want to stop you?

They cannot stop me. I have published about 650 scientific papers to date. However, young colleagues, who think critically, have no chance given these kind of manipulations. In principle, most editors of science magazines no longer accept papers that are contrary to the IPCC’s claims, regardless of the quality of the papers.

However, 97 percent of climate researchers are convinced that global warming is man-made?

This is nonsense. This number is based on dubious polls. In fact, the majority of researchers reject the claims made by the IPCC, depending on the field between 50 and 80 percent. Only meteorologists agree almost 100 percent with the IPCC. However, these people are financially dependent on the IPCC.

However, doesn’t it make sense to reduce the CO2 in principle?

Why? It is obvious that CO2 is not the main driver of temperatures. It is noteworthy that the IPCC itself has repeatedly reduced the warming trend in recent years. If a temperature increase of only 1.5 degrees Celsius is to be expected, that is not important.

Why do we hear so many warnings about climate change then?

Some people have exposed themselves heavily with their claims and obviously cannot go back now. In addition, public research money flows almost exclusively to climate alarmists. We are dealing here with a quasi-religious movement that claims to protect the environment. The fight against global warming is now set against the fight to alleviate poverty.

Which would be the right priorities?

It would be important to protect people from natural disasters such as earthquakes, volcanic eruptions and tsunamis. In addition, 25,000 people die every day because they have no access to clean drinking water. The food supply is often just as catastrophic. However, Nigeria, for example, is discouraged from using coal and thus from advancing economic development and prosperity that would reduce hunger and poverty. There are today efficient technologies to filter out air pollutants in coal use. Effectively, the fight against climate change harms people very much.

What will happen next?

Solar activity is expected to decrease over the next few decades and there will be cooling as a result. By then it will probably become clear how wrong the warnings of global warming are.

​Atmospheric science 50 years later

Anthony Sadar, American Thinker

The climate of the atmospheric science field has changed dramatically over the past few decades.  The “weather,” once considered a safe topic of conversation in polite company, has morphed into the subject of heated socio-political debate.  Besides scientists, there are celebrities, politicians, pundits, and pontiffs all contributing to the meteorological mayhem.

Fifty years ago, when the climate was not so controversial, I recorded my first weather observation.  On February 18, 1968, I noted winds from my homemade instrument perched in a tree outside my bedroom window.  I recorded weather conditions several times each day almost without fail from that time on when I was in eighth grade until I went off to college, getting my undergraduate degree in meteorology from Penn State in 1976.

From my first assignment in the profession as a weather observer at a remote site in Alaska, 160 miles above the Arctic Circle, to work as an air pollution meteorologist in private consulting and government service, a lot has changed since 1968.

Increasing computer power and computational rapidity, innovative satellite and radar technology, refinement and deployment of weather sensors, and the like tremendously expanded meteorological capabilities.  Understanding and concomitant forecasting of atmospheric conditions reached new heights to where confidence in our ability to accurately predict the future has quickly grown, perhaps too hastily.

Throughout the decades, experiencing the downs and ups of global temperatures and its enthusiastic publicists, I learned several important lessons.

- Good scientists operate in humility.  Arrogance leads to errors.

- A scientist must be free to explore any hypothesis, theory, or doubt.  Truth is not the winner of a “consensus” popularity contest.

- Science literacy means appreciating the difference between knowledge, on the one hand, and assumptions, guesses, and beliefs on the other.

- Political science pressure negatively influences natural science outcomes.  Scientific practice works to discover facts, not invent them.

- Crisis-mongering is particularly harmful to climate science.  Crisis-mongering tends to soak the middle class by trying to solve problems that don’t exist with solutions that don’t work, while depriving the world’s poor of a better tomorrow.

My guess is that substantial global climate changes from human activity will be limited to the small- and medium-range scales.  Whether these changes will be drastic or not depends on your perspective.  People living in cities that were once forests, with its attentive micro-scale climate change, are likely to be grateful for the change.  Others may see all those city-dwellers as the problem.  Potential mesoscale alterations of storm tracks will benefit some while dissing others.  Measured, long-term, global-scale impacts can just as likely be small and beneficial as large and catastrophic.

I don’t know what the atmosphere will be like fifty years from now.  But one thing that seems certain is that the climate of atmospheric science research and application will benefit enormously from constructive independent thinking, not from rigid conformity to groupthink and outcomes induced by politicized government largesse.

Weather, not human-caused CO2-fueled global warming, is responsible for California wildfires

Robert W. Endlich

2017 featured incredibly intense, damaging wildfires in California: first the Wine Country fires of October, and later the massive Thomas Fire in December. Each destroyed hundreds of homes, the latter in many of the affluent suburbs and enclaves northwest of Los Angeles and Hollywood.

The Thomas Fire is the largest in modern California history, with over 1000 structures destroyed. The fires and subsequent mudslides killed over 60 people and left many others severely burned or injured.

California Governor Jerry Brown almost predictably blamed human-caused, carbon dioxide-fueled global warming and climate change, specifically droughts, as the cause of these conflagrations. During a December 9 visit to Ventura County, he again insisted that the drought conditions were the “new normal.” While acknowledging that California has experienced “very long droughts” throughout its history, he claimed that the returning dry spells of recent decades were “very bad” and would be “returning more often” because of manmade climate change.

It’s a nice attempt to deflect blame from his state’s ultra-green policies and poor forest management practices. Moreover, Governor Brown is just wrong about the alleged role of manmade climate change, as an examination of meteorological and climate data demonstrates. NOAA’s rainfall records for California show rainfall slightly increasing in California over the 125-year period since rainfall records began.

Meteorological conditions, as they develop over the course of a year, and during the multi-year El-Nino to La Nina cycles known as ENSO (El Nino Southern Oscillation), result in conditions that favor wildfires in California. Fire is a part of nature, much to the consternation of those who blame manmade climate change, and much to the dismay of those whose lives are disrupted by wildfire events such as these.

Of course, they can be - and are - worsened and even made catastrophic by failures to manage forests properly, especially when hundreds of homes are built near forests, and when weather and climate cycles intersect with those failures and incidents that start a wildfire.

In the United States, the “Sun Belt” from California to Florida receives that name because a feature of global circulation causes descending air about 30 degrees north and south of the equator. At the surface, this “Hadley cell” is evident in high pressure monthly and annual means (or averages); it’s also called the subtropical high and subtropical ridge.

In the northern hemisphere, the position and strength of the subtropical ridge changes over the course of the year, getting stronger and moving further north in the summertime.

In California that poleward migration of the subtropical ridge diverts rain-producing storm systems poleward to the north, resulting in an almost complete loss of rainfall in the summer. The annual Los Angeles climatology illustrated in Figure 1 helps tell the story of the California wildfire season.

With this information, if we think critically, the usual situation is for vegetation to sprout in wet winter months, grow - and then dry out because of the lack of summer rainfall, causing vegetation to be driest in late summer and early fall.

This is exactly the situation described in a recent article that mentions October as the worst month for wildfires and quotes University of California fire expert Max Moritz, who says “By the time you get to this season, right when you’re starting to anticipate some rain, it’s actually the most fire prone part of the year.” Power line and other management failures increase the likelihood of disaster.

Yet another factor is the failure or refusal of government agencies to permit the removal of dead, diseased and desiccated trees and brush from these woodlands - especially in the broad vicinity of these communities. In fact, California forests have 129 million dead trees, according to the US Forest Service. Together, these factors all but ensure recurrent conflagrations and tragic losses of property and lives.

As autumn sets in, the first cold frontal passages and cold air masses build into Nevada and adjacent states, and a northeasterly pressure gradient develops over California. Because of atmospheric physics, a process called adiabatic compression causes hot, dry winds to develop, often quickly and dramatically.

The Wine country fires of 2017 began suddenly during the evening of October 8, with development of the first fierce Diablo Winds of the season. Contemporary news accounts link the onset of ten fires within ninety minutes to PG&E power poles falling, many into dry trees. In one account, a Sonoma County resident said “trees were on fire like torches.”

The Mercury News carried a story saying that Governor Brown had vetoed a unanimously - passed 2016 bill to fund power line safety measures. But the governor wants to spend still more money combating manmade climate change and compelling a major and rapid shift from fossil fuels to expensive, unreliable, weather-dependent wind and solar power for electricity generation

There was a significant cooling of Pacific Ocean temperatures from the peak of the 2015-16 El Nino to December 2017, such that La Nina conditions have developed in recent months. This distinct pattern shift brought distinctly drier conditions from southern California and Arizona to Florida and South Carolina.

This pattern shift is part of the evolution of temperature and precipitation change areas characteristic of the ENSO sequence of events. Contrary to Governor Brown’s politically inspired assertions, it clearly is not the result of human-caused, CO2-fueled global warming.

This brings us to the devastating Thomas Fire, which began on the evening of 4 December 2017, and was not completely contained by New Year’s Eve, 31 December. Behavior of this fire was controlled by a large-in-extent and long-in-duration Santa Ana Wind event, and like the previous Wine Country Fire, was dominated by high pressure over Nevada and persistent hot, dry, strong down-slope winds that commonly occur during such meteorological conditions.

In short, it is meteorological conditions which create the environment for the spread of such fires. This year’s changeover from wet El Nino to dry La Nina conditions played a significant part in the atmospheric set-up for the 2017 fires.

In Australia, it is widely accepted that fuel reduction actions are an accepted practice in fire management.

This is not the case in the USA, where considerable debate still rages over the issue, and where environmentalists, politicians, regulators and courts have united to block tree thinning, brush removal and harvesting of dead and dying trees. The resulting conditions are perfect for devastating wildfires, which denude hillsides and forest habitats, leaving barren soils that cannot absorb the heavy rains that frequently follow the fires - leading to equally devastating, equally deadly mudslides.

In fact, environmental regulations associated with ill-fated attempts to help the spotted owl have eliminated logging and clearing throughout California and most of the Mountain West - with catastrophic results. Special legislation has been drafted to begin to address this problem.

However, it is uncertain whether the legislation will be enacted and whether timber harvesting and/or fuel reduction strategies can be implemented in time to address the fuel excesses that exacerbate these dangerous conditions, setting the stage for yet another round of infernos and mudslides that wipe out wildlife habitats, destroy homes and communities, and leave hundreds of people dead, injured or burned horribly. When will the responsible parties be held accountable, and compelled to change their ways?
