Steve welcomes geologist and CO2 Coalition Executive Director Gregory Wrightstone to examine President Trump’s accusation that Canadian officials have shown “willful negligence” in managing the wildfires sending smoke across the United States. Wrightstone challenges the dominant climate-crisis narrative and argues that land management, forest policy, and fire prevention deserve far more scrutiny. They discuss whether…
CO2 Coalition member Dr. William van Wijngaarden, a physicist at York University, provides a clear, evidence-based review of current scientific interpretations and observational data on global climate, focusing on key physical mechanisms and measurements rather than alarmist narratives. This presentation was produced for Canadians for Sensible Climate Policy (CSCP) in collaboration with The Canadian Freedom…
“Eastern Lane County Catastrophic Wildfires, Toxic Smoke & Opportunity” is a 59-minute presentation by Dr. Bob Zybach to the Cottage Grove 912 Project on May 5, 2026.

In this episode of Climate Debrief, Rob Louw joins Angela Wheeler and offers a detailed look at the greenhouse effect and the role of carbon dioxide in Earth’s atmosphere. He explains how radiative transfer works, why additional CO2 produces diminishing warming, and how temperature profiles in the troposphere and stratosphere influence heat loss to space.…
In this episode of Climate Debrief, Angela Wheeler sits down with ecologist Jim Steele. They explore the concept of “zonerism”—the use of selective facts to draw misleading conclusions. Steele draws on decades of field research in the Sierra Nevada. He explains how local environmental changes matter. He also highlights natural climate cycles like El Niño…
