Rebuttals to Ten Typical False Claims by Climate Alarmists

Ice Cap | March 2, 2018

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 #1: Heat waves are increasing at an alarming rate and heat kills
Claim #2: Global warming is causing more hurricanes and stronger hurricanes.
Claim #3: Global warming is causing more and stronger tornadoes
Claim #4: Global warming is increasing the magnitude and frequency of droughts and floods.
Claim #5: Global Warming has increased U.S. Wildfires
Claim #6: Global warming is causing snow to disappear
Claim #7: Global warming is resulting in rising sea levels as seen in both tide gauge and satellite technology
Claim #8: Arctic, Antarctic and Greenland ice loss is accelerating due to global warming
Claim #9: Rising atmospheric CO2 concentrations are causing ocean acidification, which is catastrophically harming marine life
Claim #10: Carbon pollution is a health hazard

Claim #1: 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 #2: 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 #3: 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 to date has 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 #4: 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 #5: 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 #6: 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 and summer. 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 #7: 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 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 Mörner, 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 #8: 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 #9: Rising Atmospheric CO2 Concentrations Are Causing Ocean Acidification, which Is Catastrophically Harming Marine Life

Summary of Rebuttal

As the air’s 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 #10: 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.

This material is derived from the Fifth Supplement to Petition for Reconsideration of the Climate Endangerment Finding filed with the USEPA on February 9 by the Concerned Household Electricity Consumers Council (CHECC).

February 20, 2018 CHECC Press Release

Electricity Consumers File New Study in Their Call for EPA to Reopen its Endangerment Finding

Key Points:

o Just Released, new research findings demonstrate that Ten Frequent Climate Alarmists’ Claims have each been Rebutted by true experts in each Field by simply citing the most relevant and credible empirical data.

o The new results invalidate 10 very frequent Alarmist Claims in recent years, and thereby also invalidate the so-called “lines of evidence” on which EPA claimed to base its 2009 CO2 Endangerment Finding.

o If the Endangerment Finding is not vacated, whether the current administration likes it or not, it is certain that electric utility, automotive and many other industries will face ongoing EPA CO2 regulation.

This scientifically illiterate basis for regulation will raise U.S. energy prices thereby reducing economic growth, jobs and national security.

February 20, 2018

On February 9, 2018, The Concerned Household Electricity Consumers Council (CHECC) submitted a fifth Supplement to their Petition to provide additional new highly relevant and credible information. It relates to variables other than temperature describing the Earth’s Climate System. With each of EPA’s three Lines of Evidence purporting to support their 2009 Endangerment Finding already shown in the CHECC petition and its first 2 Supplements to be invalid, EPA has no proof whatsoever that CO2 has had a statistically significant impact on global temperatures.

The Council’s original Petition and First Supplement to Petition demonstrated that the Endangerment Finding is nothing more than assumptions that have each been disproved by the most relevant empirical evidence from the real world. The original Petition was substantially based on a major peer-reviewed 2016 scientific paper by James Wallace, John Christy and Joseph D’Aleo (Wallace 2016) that analyzed the best available temperature data sets and “failed to find that the steadily rising atmospheric CO2 concentrations have had a statistically significant impact on any of the 13 critically important tropical and global temperature time series data sets analyzed.” The full text of Wallace 2016 may be found here”>here.

First Supplement to Petition was substantially based on a new April 2017 peer reviewed scientific paper, also from the same authors (Wallace 2017A). Wallace 2017A can be found here. Wallace 2017A concluded that once impacts of natural factors such as solar, volcanic and ENSO activity are accounted for, there is no “natural factor adjusted” warming remaining to be attributed to rising atmospheric CO2 levels.

The Second Supplement to the Petition relied on a third new major peer reviewed scientific paper from James Wallace, Joseph D’Aleo and Craig Idso, published in June 2017 (Wallace 2017B). Wallace 2017B analyzes the GAST data issued by U.S. agencies NASA and NOAA, as well as British group Hadley CRU. (Wallace 2017B can be found here) In this research report past changes in the previously reported historical data are quantified. It was found that each new version of GAST has nearly always exhibited a steeper warming linear trend over its entire history. And, this result was nearly always accomplished by each entity systematically removing the previously existing cyclical temperature pattern. This was true for all three entities providing GAST data measurement, NOAA, NASA and Hadley CRU.
The Second Supplement to Petition states: Adjustments that impart an ever-steeper upward trend in the data by removing the natural cyclical temperature patterns present in the data deprive the GAST products from NOAA, NASA and Hadley CRU of the credibility required for policymaking or climate modeling, particularly when they are relied on to drive trillions of dollars in expenditures.

The invalidation of the adjusted GAST data knocked yet another essential pillar out from under the lines of evidence that are the claimed foundation of the Endangerment Finding. As the Second Supplement to Petition stated: It is therefore inescapable that if the official GAST data from NOAA, NASA and Hadley CRU are invalid, then both the “basic physical understanding” of climate and the climate models will also be invalid. The scientific invalidity of the Endangerment Finding becomes more blindingly obvious and undeniable with each day’s accumulation of reliable empirical data -and, the willingness of more scientists to come forward with such new evidence. (See here.) Perhaps recognizing this fact, Climate Alarmist have over time gone from focusing on Global Warming, to Climate Change to simply fear of Carbon. Thus, this research sought to determine the credibility of Ten (10) very frequently cited Climate Alarmists Claims. Above are Rebuttals to each of these ten typical climate alarmists’ claims. The rebuttal authors are all recognized experts on their topic and each rebuttal demonstrates the claim fallacy by merely citing the most credible empirical data.

The Conclusion of the Fifth Supplement

The invalidation of the three lines of evidence upon which EPA attributes global warming to human GHG emissions breaks the causal link between human GHG emissions and global warming. This in turn necessarily breaks the causal chain between human GHG 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.

Nevertheless, these alleged downstream effects are constantly cited to whip up alarm and create demands for ever tighter regulation of GHG emissions involving all fossil fuels, not just coal. EPA explicitly relied on predicted increases in such events to justify the Endangerment Finding. But there is no evidence to support such Alarmist Claims, and copious empirical evidence that refutes them. The enormous cost and essentially limitless scope of the government’s regulatory authority over GHG emissions cannot lawfully rest upon a collection of scary stories that are conclusively disproven by readily available empirical data.

The scientific invalidity of the Endangerment Finding becomes more blindingly obvious and undeniable with each day’s accumulation of reliable empirical data. It is time for an honest and rigorous scientific re-evaluation of the 2009 CO2 Endangerment Finding. The nation has been taken down a tragically foolish path of pointless GHG/CO2 regulations and wasteful mal-investments to “solve” a problem which does not actually exist. Our leaders must summon the courage to acknowledge the truth and act accordingly.

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.

The Council brought its Petition because the Obama-era greenhouse gas regulations threaten, as President Obama himself conceded, to make the price of electricity “skyrocket.” But clearly CO2 regulation does not just raise electricity prices, it raises all fossil fuel prices. America can have, and must have, the lowest possible energy costs in order to attain and maintain its energy, economic and national security.
