Quote of the Week: “We’ve arranged a global civilization in which most crucial elements . . . profoundly depend on science and technology. We have also arranged things so that almost no one understands science and technology. This is a prescription for disaster.”

“Pseudoscience differs from erroneous science. Science thrives on errors, cutting them away one by one. False conclusions are drawn all the time, but they are drawn tentatively. Hypotheses are framed so they are capable of being disproved… Science gropes and staggers toward understanding.”Carl Sagan [H/t Roger Klein]

Number of the Week: – 13


By Ken Haapala, President, Science and Environmental Policy Project (SEPP)

The Greenhouse Effect: Last week TWTW presented an essay by Richard Lindzen, an accomplished atmospheric physicist, and William Happer, a distinguished physicist specializing in Atomic, Molecular and Optical (AMO) Physics, which includes research into matter-matter and light-matter interactions (electromagnetic radiation-matter interactions). Over 150 years ago, John Tyndall recognized that it is the interactions between outgoing infrared radiation (electromagnetic radiation) and certain gases that slow the loss of heat, keeping the land masses from deeply freezing at night. The dominant greenhouse gas is water vapor, covering a broad range of wavelengths, or frequencies, in the infrared spectrum. Its effectiveness crashes when water vapor freezes out in the tropopause, approximately 60,000 feet (18,000 meters) at the equator and roughly 20,000 feet (6,000 meters) at the poles

Carbon dioxide (CO2) covers only a small range of wavelengths (or frequencies) but is highly effective in that small range of wavelengths. Once all infrared radiation in those narrow ranges is being blocked (delayed), the range of wavelengths (or frequencies) is said to be saturated. Expanding saturated ranges to neighboring wavelengths (or frequencies) requires significantly more carbon dioxide. The wavelengths (or frequencies), for which CO2 is an effective greenhouse gas were saturated well before humans began adding CO2 to the atmosphere. Human emissions of CO2 have little effect on temperatures according to Lindzen and Happer. However, their work and that of others is being ignored by those who wish to create fear of dangerous warming from carbon dioxide. As Lindzen and Happer wrote:

“We are both scientists who can attest that the research literature does not support the claim of a climate emergency. Nor will there be one. None of the lurid predictions — dangerously accelerating sea-level rise, increasingly extreme weather, more deadly forest fires, unprecedented warming, etc. — are any more accurate than the fire-and-brimstone sermons used to stoke fanaticism in medieval crusaders.

“No scientist familiar with radiation transfer denies that more carbon dioxide is likely to cause some surface warming. But the warming would be small and benign. In fact, history shows that warmings of a few degrees Celsius — which extended growing seasons — have been good for humanity.” [Boldface added]

“More carbon dioxide will certainly increase the productivity of agriculture and forestry. Over the past century, the earth has already become noticeably greener as a result of the modest increase of CO2, from about 0.03 percent to 0.04 percent of atmospheric molecules. More CO2 has made a significant contribution to the increased crop yields of the past 50 years, as well. The benefits to plants of more CO2 are documented in hundreds of scientific studies.”

“Americans should not be stampeded into a disastrous climate crusade.”

Global climate modelers claim they take radiation transfer into account. However, the results of their work show that they do not do so correctly. Roy Spencer demonstrates that global ocean temperatures are warming at about 50% of the rate of climate model projections. More importantly for the greenhouse effect, climate models predict atmosphere warming 2.5 to 3 times that which is actually occurring. These errors would be unacceptable in a high school physics course, but they are acceptable to the UN Intergovernmental Panel on Climate Change (IPCC); whose followers include the US Global Change Research Program (USGCRP) made up of 13 federal agencies. As Spencer writes:

“A related issue is how much the deep oceans are warming. As I have mentioned before, the (inarguable) energy imbalance associated with deep ocean warming in recent decades is only about 1 part (less than 1 Watt per sq. m) in 300 of the natural energy flows in the climate system.

“This is a very tiny energy imbalance in the climate system. We know NONE of the natural energy flows to that level of accuracy.

“What that means is that global warming could be mostly natural, and we would not even know it.

“I’m not claiming that is the case. I am merely pointing out the level of faith that is involved in the adjustments made to climate models, which necessarily produce warming due to increasing CO2 because those models simply assume that there is no other source of warming.

“Yes, more CO2 must produce some warming. But the amount of warming makes all the difference to global energy policies.

“Seldom is the public ever informed of these glaring discrepancies between basic science and what politicians and pop-scientists tell us.

“Why does it matter?

“It matters because there is no Climate Crisis. There is no Climate Emergency.

“Yes, irregular warming is occurring. Yes, it is at least partly due to human greenhouse gas emissions. But seldom are the benefits of a somewhat warmer climate system mentioned, or the benefits of more CO2 in the atmosphere (which is required for life on Earth to exist).

“But if we waste trillions of dollars (that’s just here in the U.S. — meanwhile, China will always do what is in the best interests of China) then that is trillions of dollars not available for the real necessities of life.

“Prosperity will suffer, and for no good reason.”

Others familiar with radiation transfer agree that energy imbalance is so tiny that it cannot be pinned down. See links under Challenging the Orthodoxy.


Keeping the Dragon: In his book, The Demon-Haunted World: Science as a Candle in the Dark, Carl Sagan explains the scientific method to the general public. The scientific method requires skeptical, critical thinking and rigorous testing of concepts against physical evidence. He develops the amusing concept of having a fire-breathing dragon in his garage. A visitor cannot see it because it is invisible, it does not leave footprints because it floats, and so on. The existence of the dragon cannot be tested by using physical evidence. The same is true of the claim that carbon dioxide is causing dangerous warming. The advocates of the claim do not test it against the correct physical evidence.

Sagan explains what he calls a “baloney detection kit” for separating what he calls “pseudoscience” from actual science. The kit involves testing concepts against physical evidence, confirmation of the facts and review of all points of view on the concept. [Similar to Richard Feynman requiring testing a hypothesis against all the physical evidence.] Sagan’s kit also includes logical fallacies that need to be avoided when presenting a hypothesis. He emphasizes the importance of skeptical thinking.

Politically, Sagan was considered to be a liberal. It is ironic that many politically liberal people accuse those who challenge the claims of dangerous carbon dioxide-caused global warming as being skeptics – precisely what Sagan advocated. See links under Seeking a Common Ground.


Feeding the Dragon: President Joe Biden announced an expensive, extensive revamping of the American economy, particularly in energy, to “fight global warming” from carbon dioxide. Warming and cooling of the planet is natural, and evidence shows the human contribution to increasing the greenhouse effect is slight, perhaps not even clearly measurable at this time. Thus, the fight appears to be against the invisible dragon in the garage.

Power expert Donn Dears has two essays on the extent of the problem being created by Biden’s proclamations, one on nuclear power and the second on coal, natural gas, and supply of energy. Roger Pielke Jr. calculates that: “By Earth Day 2022 the US will have needed to close more than 100 power plants that were producing electricity in January 2021 in order to be close to the trajectory set forth by the new emissions targets.” TWTW speculates that President Biden will do a Jim Hansen who predicted great sea level rise. When it was not occurring as predicted, he claimed it will all come at the end of the 21st century.

Patrick Michaels discusses some of the legal issues the Biden plan faces. Others bring up similar problems with Biden’s plan. Perhaps the most bizarre will be the dance the BASIC countries (Brazil, South Africa, India, and China) are taking with Biden’s climate envoy, John Kerry.

Over the past thirty years, South Asia has emerged from extreme poverty, something that few in Washington understand. An important part of this emergence is the use of fossil fuels. Leaders of these countries have every reason to suspect that the UN claims of dangerous global warming are nothing but an effort by neo-colonialists to suppress them. Note that the sharp departure between model forecasts of what is occurring in the atmosphere and what is being actually measured started in the mid-1990s, with model forecasts of warming far exceeding actual measurements.

Brazil is now a leading competitor with the US in bulk agriculture exports, such as maize (corn) and soybeans, despite the USGCRP declaring warming will significantly damage agriculture in the US. The leaders of all these countries appear to be more attuned to the real needs of their publics than Washington is attuned to the real needs of Americans. Washington is focused on fighting dragons. See links under Challenging the Orthodoxy, Change in US Administrations, Expanding the Orthodoxy, and Litigation Issues


How Big? Leading up to the Biden meeting on climate, it appeared that the leaders of many Western Countries were in a contest on who would make the biggest sacrifices. Of course, the leaders are far too important and too busy to make personal sacrifices, so the sacrifices would fall on the general population. Once, such a contest would be labeled masculine arrogance. Now it includes many women, so can it be labeled as self-righteous arrogance? See links under Questioning Green Elsewhere, Energy Issues – Non-US, and Energy Issues – Australia,


Why? In 1973, President Biden started his first term in the Senate. Annually, large protests against the war in Vietnam occurred in Washington. That year the Arab Oil Embargo began, causing great disruption to the economy. Further, the Nixon price controls remained on oil and natural gas. During cold weather, thousands of people were thrown out of work from the lack of natural gas. Congress passed laws forbidding power plants from using oil or natural gas exclusively.

In 1977, President Carter declared the energy crisis is the moral equivalent of war. He advocated making the most of the country’s abundant resources of coal, as well as conservation and use of renewables. The 1970s was a period of stagflation (economic stagnation, and high inflation simultaneously). Matt Ridley discusses the problems of government control of the economy by rationing and price control.

When Biden was Vice President during the Obama administration, the government promoted great spending on “shovel-ready” jobs. The net result was a growth rate coming out of a recession of less than 2% — called the great recession. During the Trump administration the economy boomed, the US became energy independent, exporting more oil and gas than it imported. During the Obama administration, small and mid-sized oil and gas companies developed the combination of hydraulic fracturing and directional drilling to solve the problem of extracting oil and gas from dense shale. The energy crisis was over.

Now, President Biden wishes to disrupt the energy industry and the economy to fight a war on dragons – mild or non-existent CO2-caused global warming? Since the analogy of war is frequently used, a better analogy would be President Johnson sending hundreds of thousands of ground troops to Vietnam without a strategic plan. When the Johnson administration was leaving, Secretary of Defense Robert McNamara asked for a report, essentially asking the question “How did we get into this mess?”

The result was the Pentagon Papers, strangely suppressed by President Nixon. Although the report is claimed to be a history of US involvement in Vietnam, what it shows to the skeptical reader is the lack of critical thinking, skeptical questioning, during the Johnson administration in deploying massive units of ground troops. Young political analysts in the White House were developing bombing plans for North Vietnam! In short, the US committed great resources to fight an enemy it did not understand, under poor leadership at the top, using methods that were ineffective. Unfortunately, the Biden climate plan has similar weaknesses. See links under Science, Policy, and Evidence and Article # 2.


Solar Cycles: We do not fully understand the sun and the extent it influences the globe’s climate. John Maunder writes:

“One challenge for researchers working to predict the Sun’s activities is that scientists don’t yet completely understand the inner workings of our star. Plus, some factors that play out deep inside the Sun cannot be measured directly. They have to be estimated from measurements of related phenomena on the solar surface, like sunspots.”

In November, scientists at the US National Center for Atmospheric Research (NCAR) published a paper predicting the Sunspot Cycle that started that fall could be one of the strongest since about 1755. They did so by using the 22-year (Hale) magnetic cycle rather than the more customary 11-year sunspot cycle. Their prediction of a strong 22-year cycle is in contrast with most predictions of a weak 11-year sunspot cycle.

Separately, three independent scientists, including Willie Soon and David Legates, directors of SEPP, applied machine learning algorithms and analyses to the World Data Center’s newly constructed annual sunspot time series (1700–2019; Version 2.0). They found that the variability in the approximate 11-year Sunspot Cycle is closely connected with a 120-year oscillatory magnetic activity variation. They forecast an extended solar minimum to about 2050.

From this, we see two distinctly separate hypotheses which the Sun will test. It is an exciting time for those who follow the sun. See links under Science: Is the Sun Rising? and Commentary: Is the Sun Rising?



14th ICCC Rescheduled: The 14th International Conference on Climate Change presented by The Heartland Institute has been rescheduled to October 15 to 17, 2021, at Caesars Palace in Las Vegas. See https://climateconference.heartland.org/




SEPP is conducting its annual vote for the recipient of the coveted trophy, The Jackson, a lump of coal. Readers are asked to nominate and vote for who they think is most deserving, following these criteria:

  • The nominee has advanced, or proposes to advance, significant expansion of governmental power, regulation, or control over the public or significant sections of the general economy.
  • The nominee does so by declaring such measures are necessary to protect public health, welfare, or the environment.
  • The nominee declares that physical science supports such measures.
  • The physical science supporting the measures is flimsy at best, and possibly non-existent.

The past recipients, Lisa Jackson, Barrack Obama, John Kerry, Ernest Moniz, Michael Mann, Christiana Figueres, Jerry Brown, AOC, and Neil Ferguson are not eligible. Generally, the committee that makes the selection prefers a candidate with a national or international presence. The voting will close on July 31. Please send your nominee and a brief reason why the person is qualified for the honor to [email protected] Thank you.

Number of the Week: 13. Joseph D’Aleo of WeatherBell Analytics and ICECAP has updated his list of 13 common claims about the climate that have been rebutted based on credible, relevant physical evidence. The list links to reviews by recognized experts in the specific field. The list includes heat waves, hurricanes, tornadoes, droughts and floods, wildfires, etc. The list of common claims, Bandwagon Science, based on little or no direct physical evidence, is astonishing and usually wrong. Unfortunately, it influences government policies. See link under Challenging the Orthodoxy.

Marine life is fleeing the equator to cooler waters. History tells us this could trigger a mass extinction event

By Anthony Richardson, The University of Queensland; Chhaya Chaudhary, University of Auckland; David Schoeman, University of the Sunshine Coast, and Mark John Costello, University of Auckland, The Conversation, Apr 7, 2021 [H/t WUWT]


“At the end of the Permian geological period about 252 million years ago, global temperatures warmed by 10℃ over 30,000-60,000 years as a result of greenhouse gas emissions from volcano eruptions in Siberia.

“A 2020 study of the fossils from that time shows the pronounced peak in biodiversity at the equator flattened and spread. During this mammoth rearranging of global biodiversity, 90% of all marine species were killed.”

[SEPP Comment: There has been a great deal of speculation, but the eruption of the Siberian Traps probably released massive amounts of sulfur dioxide, hydrogen sulfide, and hydrogen halides, not conducive to life.

However, Bellworthy and Fine’s cold stressed corals did not die and recovered once water temperatures returned to normal. Experimental corals were maintained at normal temperatures and then underwent a second test – an anomalously hot summer. “It was an important discovery for us to understand that even those individuals that suffered the cold winter stress, still did not bleach at the high temperatures,” says Bellworthy.
