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.”

Comments on the History and Current State of World Energy

Robert W. Endlich

 [Preface: This post’s topics (Coal, Oil, Gas, Fracking, Nuclear, “End of Oil” Energy Stories, unusual hydrocarbon deposits, and some estimates of Petroleum Reserves) are broad reaching; it is difficult to encapsulate all such subjects in an internet post of this type. This is my ‘best effort,’ within these obvious constraints.]

INTRODUCTION

This post provides comments on the history and current state of world energy and concerns stated by climate alarmists regarding global warming.

The climate alarmists’ concerns about our use of fossil fuels as the source of “human-caused, CO2-fueled, global warming” begin with the Industrial Revolution, in the 19th Century. when coal use became widespread. Our ’Friends’ at the National Resources Defense Council, the NRDC, in their article’s lead paragraph, Global Warming 101, come right out and say it:

“Since the Industrial Revolution, the global annual temperature has increased in total by a little more than 1 degree Celsius, or about 2 degrees Fahrenheit.”

This NRDC statement is written as if temperature never changed before the Industrial Revolution. In this Continue reading “Comments on the History and Current State of World Energy”

Proof that Carbon Dioxide Does Not Control Earth’s Temperature

nor do human emissions of CO2 from today’s burning of hydrocarbon fuels cause significant temperature increases.

Notes:
1. When a chemical compound is in brackets, e.g., “<CO2> PPM,” understand this as “atmospheric concentration of CO2 in Parts per Million.”
2.  Most Time Series are plotted with increasing time left to right, but sometimes they are plotted time increasing right to left.

INTRODUCTION

There are numerous claims by many Global Warming Adherents, Alarmists, and the UN’s Intergovernmental Panel on Climate Change that burning

fossil fuels and subsequent increases of <CO2> is driving warmer temperatures because of an alleged CO2 Radiative Forcing effect. However, when compared with past Earth Temperatures, the data graphics below show that present levels of CO2 are not influencing Earth temperatures to any measurable effect, nor are human emissions of CO2 causing any significant rise in temperatures.

Most of the data quoted by the IPCC is from the period of time subsequent to “The Great Climate Shift of 1976.” Continue reading “Proof that Carbon Dioxide Does Not Control Earth’s Temperature”

Comment on: “Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate”

I received a Bachelor’s in Geology, Rutgers, 1962, Basic Meteorology certificate from Texas A&M, 1964, and an MS in Meteorology at The Pennsylvania State University, 1969. I served as a Weather Officer in the US Air Force for 21 years, 1963-1984, including overseas tours on Guam, in Thailand and Viet Nam, and in Germany, during the Cold War. In 1964, I was elected to Chi Epsilon Pi, the National Meteorology Honor Society, while an Air Force Basic Meteorology student at Texas A&M University. I worked as a Meteorologist for 49 years: 21 in the Air Force, 18 in the U.S. Army Atmospheric Sciences Laboratory, White Sands Missile Range, NM, and 10 in the Physical Science Laboratory Continue reading “Comment on: “Critical Review of Impacts of Greenhouse Gas Emissions on the U.S. Climate””

Death Valley World Record 134 deg. F is Biased ~10 deg. Too High

Roy W. Spencer, Ph. D.

[This blog by Dr. Roy W. Spencer was originally published on his blog site on 8 November 2024.  It is reproduced here under the fair use doctrine and with standing permission from the author. Ed]

Key Points:

      • Over the years, a few commentators have have argued that the world record highest temperature of 134 deg. F at Death Valley, CA recorded on July 10, 1913 is physically implausible.
      • Here I show quantitatively that the 134 deg F temperature is biased high, by about 10 deg. F.
      • Extensive historical research by William T . Reid has suggested the person making the temperature observations at Greenland Ranch likely replaced the official measurements from a thermometer in a Stevenson screen shelter with other measurements made next to the adobe living quarters.

Update #1 (11/8/2024): Fixed a few typos.

Update #2 (11/8/2024): For those messaging me about Furnace Creek temperatures reaching 130 deg. F in recent years, see Bill Reid’s summary of side-by-side measurements made there [and reported at an AMS meeting] showing the non-aspirated “official” equipment produces temperatures 2-3 deg. too high during light wind conditions.

Update #3 (11/9/2024): Bill Reid corrected my use of the term “mountain” stations to describe those not in Death Valley. Many of those stations are at desert plateau sites, so I have changed the term to “higher elevation” stations. I have also asked Bill to provide additional thoughts on this issue, which will be the next blog post here.

BACKGROUND

The “official” world record highest near-surface air temperature is 134 deg. F, recorded in Death Valley, California on July, 10, 1913 at Greenland Ranch, California an isolated location with no similarly sited stations with which to compare (say, within 10 miles and below sea level). Greenland Ranch was a man-made oasis created by the Borax people around the turn of the 20th Century, with water piped in from a nearby mountain. It has a rich history, but always against a backdrop of oppressive summer heat that few visitors (and even workers) could endure.
