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 Vijay Jayaraj Calling carbon dioxide (CO2) a beneficial gas could draw mockery or moral outrage. Perhaps even an accusation of “denying science.” For nearly two decades, political forces successfully branded this life-giving gas a toxic agent, a cause of both floods and droughts and a thief of the grandchildren’s future. One solution was to… 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
