By John Droz Jr., originally published on his Substack: Dr. Roger Pielke, jr is a well-known person in the climate arena, although his Science credentials are a bit wanting (e.g., his PhD is in political science). I worked with his dad (Dr. Roger Pielke, sr) for many years and he was a bona-fide climate scientist,… Continue Reading
By Vijay Jayaraj Imagine the irony of labeling a substance as “hazardous” only to discover that the true peril lies not in the substance but in the act of its vilification. That is the case with carbon dioxide (CO₂) and how it has been mischaracterized to establish globally suicidal energy policies. In 2009, the U.S.… Continue Reading

By Brian C Joondeph When Americans hear about carbon dioxide (CO2), it’s often shown as a harmful pollutant that threatens the planet. Politicians, activists, and media outlets warn that if we don’t reduce emissions right away, disaster will happen. Preeminent “climate scientist” Al Gore told Congress in 2007, “The science is settled. Carbon dioxide emissions… Continue Reading

By Vijay Jayaraj Having declared carbon dioxide (CO₂) and other greenhouse gases (GHGs) to be harmful pollutants, the Environmental Protection Agency’s (EPA’s) 2009 endangerment finding has been the cornerstone of wrongheaded climate regulation, an impediment to economic growth and destroyer of livelihoods. All the result of rulemaking that puts ideology ahead of science. Empowered to… Continue Reading
In 2009, the United States Environmental Protection Agency, under the auspices of the Clean Air Act, falsely determined that carbon dioxide was a pollutant. This is known as the Endangerment Finding and has been used since then to enable EPA to regulate and control CO2 emissions. It is this authority that is being used… Continue Reading

by Gregory Wrightstone Is carbon dioxide — two pounds of which each of us exhales daily — a pollutant? And are catastrophes increasing as a result of higher concentrations of the gas? Physics — along with a few other branches of science — says no. Nonetheless, in a landmark 2007 Supreme Court ruling, the EPA… Continue Reading
