Cruces Atmospheric Sciences Forum – In science, the debate is never over!
[def from Wikipedia.] Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth’s atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume.[3] Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas.
[added comments] While carbon dioxide is a “greenhouse” gas and it does absorb energy in some infrared wavelength bands, many scientists will argue that its affect on average global temperatures have been considerably exaggerated by the proponents of catastrophic anthropogenic global warming. In order to derive effects extreme enough to be considered catastrophic, they have had to rely on strong positive feedback resulting in much larger effects than CO2 could produce without any feedbacks. Many prestigious scientists disagree with that and some even suspect the feedback is not only much less than estimated, but may even be negative.
One must always consider that contrary to that which is frequently stated by climate activists/alarmists, the debate is never over in science.
On Sunday, August 16th the National Weather Service in Las Vegas, Nevada sent out a Tweet highlighting a new maximum daily temperature of 130°F in Death Valley:
Predictably, the media jumped on this number with the Los Angeles Times saying “…possibly the highest mercury reading on Earth since 1913“. Even the Continue reading “Media hypes new 130°F Death Valley Temperature – but it’s still short of the 134°F all-time record”
[This article was originally published on June 29, 2020 by EnvironmentalProgress.org. We are reproducing it here under the fair use doctrine. It is a refreshingly honest presentation by Michael Shellenberger, an environmentalist who once accepted and actively promoted the idea that catastrophic anthropogenic global warming was occurring. After critically examining the AGW hypothesis, he has concluded that it is not supported by the facts, and consequently is apologizing for having participated in this misinformation campaign. Ed.]
On behalf of environmentalists everywhere, I would like to formally apologize for the climate scare we created over the last 30 years. Climate Continue reading “On Behalf Of Environmentalists, I Apologize For The Climate Scare”
Art Robinson, Ph.D., calls out those using the “scientist” descriptor to spread fear among us
“Let’s Send a Scientist to the Oregon Senate” headlines a flier for my State Senate campaign. We are considering dropping “Scientist.”
Scientists enjoy learning new facts about the physical world. They have been respected largely because some of their discoveries have led to Continue reading “I’m a ‘scientist’ — a label that has lost its luster”
Climate scientist Patrick Michaels says there has been a profound suspension of the normal rules of science in the climate arena.

Burnett: You coauthored a book titled Lukewarming: The New Climate Science that Changes Everything. What is the thesis of the book?
Michaels: Global warming is often presented as one of two alternative visions: left unattended, it will bring about an unmitigated disaster with tremendous consequences to humanity and the planet; or there is really “no such thing”—meaning little to no warming and little to no influence of human greenhouse-gas emissions on climate.

There is a third way. I call it the ‘lukewarm” synthesis, which holds the surface temperature indeed is a bit warmer than it was around 1900, that Continue reading “Climate Data Is Being Misused and Manipulated, Says Award-Winning Scientist”
Global temperatures are likely only rising at a pace of 0.13 degrees Celsius per decade, which is even closer to skeptic predictions.

A newly published paper, titled “Evaluating the Performance of Past Climate Model Projections,” mistakenly claims climate models have been remarkably accurate predicting future temperatures. The paper is receiving substantial media attention, but we urge caution before blindly accepting the paper’s assertions.
As an initial matter, the authors of the paper are climate modelers. Climate modelers have a vested self-interest in convincing people that climate Continue reading “Updated Analysis Shows Climate Models Continue To Predict Too Much Warming”
