Climate Debrief

Part 3: Rob Louw joins Angela Wheeler on Climate Debrief to explore the science of photosynthesis and the essential role carbon dioxide plays in plant life. He examines how atmospheric CO₂ has changed throughout Earth’s geological history and how plants adapted to lower concentrations over time.

Vijay Jayaraj joins Angela Wheeler on Climate Debrief to examine the history of the modern environmental movement and the rise of today’s climate crisis narrative. Drawing on historical and environmental data, he challenges claims about worsening extreme weather, wildfires, droughts, and heat while highlighting improvements in human life expectancy, agriculture, and global greening. Jayraj argues...

Part 3: Dr. Frits Byron Soepyan joins Angela Wheeler to examine claims about extreme weather, sea levels, ocean temperatures, and ocean acidification. He discusses historical trends in hurricanes, tornadoes, ice, sea levels, and ocean temperatures, arguing that many of these changes reflect natural variability rather than a climate crisis.  He also explores natural climate drivers such as El Niño...

Dr. Frits Byron Soepyan joins Angela Wheeler and examines the long-term history of atmospheric CO₂ and Earth’s temperature. He explains why modern CO₂ levels are low compared with much of geological history and discusses CO₂’s role in plant growth and global greening. He also explores historical temperature records, including the Little Ice Age, and argues that temperature changes cannot be explai...

Dr. James Enstrom is an epidemiologist, physicist, and longtime researcher focused on scientific integrity. In this episode of Climate Debrief, he discusses his research into air pollution, PM2.5, and public health. He explains why transparency, reproducibility, and access to data are essential to good science. Dr. Enstrom also examines the evidence behind claims linking air pollution to mortality...

Are today's catastrophic wildfires really driven by climate change, or are decades of forest management policies to blame? In this episode of Climate Debrief, Dr. Bob Zybach outlines practical steps he believes could reduce wildfire risk and restore healthier forests. Join us for an in-depth conversation about wildfire history, forest management, and the policies shaping America's landscapes.

Are today's catastrophic wildfires really driven by climate change, or are decades of forest management policies to blame? In this episode of Climate Debrief, Dr. Bob Zybach joins Angela Wheeler and shares historical evidence and firsthand experience to explain how active forest management once kept forests healthier and more resilient.  Dr. Zybach also outlines practical steps he believes could r...

Is the science behind today's climate policies as solid as it seems? In Part 2 of this Climate Debrief interview, Dr. John Dale Dunn joins Angela Wheeler to examine the origins and misapplication of the Linear No-Threshold (LNT) Theory in environmental regulation. Dr. Dunn, a board-certified emergency physician with over 50 years of experience and an inactive attorney with decades in toxicology, e...

Threshold Theory and argues that it has been misapplied to environmental regulation. He discusses toxicology, epidemiology, and the scientific principles he believes should guide public policy. John Dale Dunn has been an emergency physician for more than fifty years and an attorney (inactive) for forty years, admitted to the bars of Nebraska, Louisiana and Texas by examination. For more than thirt...

In the final part of this insightful conversation, Angela Wheeler continues her discussion with Dr. Sharon Camp, Senior Education Advisor for the CO2 Coalition and creator of the CO2 Learning Center lesson plans. Dr. Camp (Ph. D. Analytical Chemistry) dives deeper into the importance of rigorous scientific evidence in the courtroom, the limitations of climate models, challenges to scientific conse...

Angela Wheeler continues her discussion with Dr. Sharon Camp, Senior Education Advisor for the CO₂ Coalition, about her article "Muddling the Judiciary’s Understanding of Science".  Dr. Camp discusses the scientific method, the role of models and consensus in climate science, and why she believes judges should rely on rigorous evidence when evaluating scientific claims.  The conversation also expl...

In the second part of Angela Wheeler's interview with geologist Koen Vogel, Ph. D., they discuss what may have caused the massive ice sheets of the last Ice Age to melt. Drawing on peer-reviewed research, Dr. Vogel examines the evidence behind CO₂, Milankovitch cycles, and other proposed explanations, highlighting why many popular theories struggle to explain the timing and scale of the deglaciati...

In this episode of Climate Debrief, host Angela Wheeler speaks with geologist Koen Vogel, Ph. D., about one of climate science’s biggest unanswered questions: What caused the massive ice sheets of the last Ice Age to melt? Drawing on peer-reviewed research, Dr. Vogel examines the evidence behind CO₂, Milankovitch cycles, and other proposed explanations, highlighting why many popular theories strug...

In this episode of Climate Debrief, Angela Wheeler speaks with Matthew Wielicki, Ph. D., about academic freedom, climate science, and the importance of open debate.  Dr. Wielicki shares how his family's experience fleeing communist Poland shaped his views on intellectual freedom. He discusses his departure from academia, concerns about climate anxiety among students, and what he sees as a growing...

Wallace Manheimer, PhD, provides a detailed critique of climate-related statements issued by major scientific societies in this discussion with Angela Wheeler.  The conversation examines global energy trends, historical climate data, and differing international perspectives on fossil fuel use.  Dr. Manheimer also addresses the scientific role of carbon dioxide and proposes changes to improve clari...

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 and La Niña. He argues these often play a l...
