The EPA Administrator, Lee Zeldin, Rescinds the Obama-Era Endangerment Finding

 At Last! Hoorah!

Robert W. Endlich

INTRODUCTION

On 15 December 2009, during the Obama Administration, the EPA issued, in Volume 4 of the Federal Register, on page 66518, a rule, based on Section 202(a) of the Clean Air Act, stating that human greenhouse gas emissions of CO2 caused environmental and human endangerment.

On 8 April 2026 EPA Administrator Lee Zelden described his Agency’s 2026 repeal of the 2009 Endangerment Finding as reversing “decades of unthinking adherence to liberal politicians and environmental groups about the dangers of climate change.”

In the years since, various individuals and organizations have published posts and articles attempting to persuade authorities to undo this rule. Here are some of their attempts:

The Heartland Institute has these posts on this topic.

A group of authors with Dr. James P. Wallace III as lead author posted this article “On the Existence of a ‘Tropical Hot Spot and The Validity of EPA’s CO2 Endangerment Finding.’” They also published on uncorrupted Temperature Records containing natural cycles, and A Critical Look at Surface Temperature Records.”

In Testimony before the House of Representatives in 2017, Dr John Christy of the University of Alabama Huntsville showed that despite the EPA’s 2009 claims of veracity of computer models, he showed that computer models of Continue reading “The EPA Administrator, Lee Zeldin, Rescinds the Obama-Era Endangerment Finding”

During the presentation at the 21 March 2026 CASF meeting, Bill Gutman highlighted brief segments from the Joe Rogan Experience video which featured comments by Dr. Will Happer, emeritus Professor of Physics from Princeton, and Dr. Richard Lindzen emeritus Professor of Earth Atmospheric and Planetary Sciences from the Massachusetts Institute of Technology, https://open.spotify.com/episode/3ihn2aHDz9dyZU0T3Kylk3

The presentation featured several minute-long video segments, following which Bill Gutman paused the video, and asked topical questions to evoke discussion of the content by meeting attendees.

This post pertains to a couple of these segments, specifically the generally Continue reading “Some Comments on Drought in the Southwest U.S.”

What has happened to the National Academy of Sciences  – Part Two

In Part One, I described when, over a fifteen or so year period of my work assignments, I needed current knowledge of the toxicity of chemicals used in military applications. From 1976-1979, the chemicals were Unsymmetrical Dimethyl Hydrazine, and Nitrogen Tetroxide, propellants for the Air Force Titan 2 Missile. Then, 1984-1994, the chemicals were Fluorine, Nitrogen Trifluoride, and Hydrogen Fluoride (HF) [actually its deuterated fluoride isotope cousin (DF)] for the Navy’s MIRACL laser at White Sands Missile Range (WSMR).  In those days my colleagues and I respected and trusted the National Academy of Sciences Committee on Toxicology, and by inference the National Academy itself.  For me, that period in my work history ended in 1994.

DOUBTING ALLEGED CO2 CLIMATE EFFECT

My beginning of doubt into significant “human-caused, CO2-Fueled Global Warming” arose after James Hansen’s 23 Jun 1988 testimony to the Senate, Continue reading “What has happened to the National Academy of Sciences  – Part Two”

This story, “Climate Change Making Days Longer,” and the variations on it, were published Summer, 2024 by mainstream media outlets.  I mention some of their Alarmist views, as well as some Contrarian views by Heartland, and some views from our skeptical friends in the blogosphere.

I explore this subject, using a wide series of facts, measurements, observations and data, easily looked up, and typically ignored by the Alarmist press.

I cite some of both sides of this story.  I widen the discussion by including Continue reading ““Climate Change Making Days Longer,” studies say, Part ONE”

WHAT WE HAVE LEARNED ABOUT “CLIMATE CHANGE MAKING DAYS LONGER” UP TO NOW

NPR claims that humans burning fossil fuels controls sea level and that CO2 is “climate pollution.”

Regarding the NPR claim, the data show that sea level is a dynamic property of earth (Fig 3) and was meters higher than today within the historic past. There are numerous examples of this from the NMSU-A WEEK SEVEN class graphics, slides 33-146. 

One example, from 1066,  is when William the Conqueror invaded what we now call England. He landed at Pevensey Castle, which is now a mile from the English Channel and 13 ft above present Sea Level, Presentation Graphics, Slide 145.

The only way to understand this is, that when William landed in  England at Continue reading ““Climate Change Making Days Longer,” studies say, Part FOUR”
