Climate Debrief

Part 1: 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 that CO₂ has benefited plant growth and that humanity has become increasingly capable of adapting to environmental challenges. His central message is simple: look beyond the narrative, examine the data, and ask what the evidence actually shows.

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 and La Niña and their influence on weather patterns. The discussion concludes with a look at species extinctions and the role of CO₂, emphasizing its importance to plant life and questioning how much influence humans have over Earth...

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 explained by CO₂ alone.

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 and the implications for public policy.

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.

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, epidemiology, and radiation biophysics, challenges the foundational assumptions driving modern climate and environmental policies. He discusses dose-response principles, the problems with population studies, Bradford Hill criteria for causation, and why real toxicology should guide policy instead of...

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 thirty years, Dunn has been a student of environmental science, environmental laws, toxicology, epidemiology, and radiation biophysics.

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 consensus, and practical ways to strengthen science education and critical thinking for the next generation.

This series explores how science should inform policy — not politics — and why judges, educators, and citizens must prioritize empirical data over narr...

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 explores science education, critical thinking, and the growing influence of climate policy in the courtroom.

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 deglaciation. 

The discussion explores abrupt climate shifts, ancient ice sheets, and the scientific challenges of reconstructing Earth's climatic past.
