Episode #213 of The Climate Realism Show is a special edition featuring two of the most prominent voices challenging the conventional climate narrative: Greenpeace co-founder Dr. Patrick Moore and astrophysicist Dr. Willie Soon.
Patrick Moore helped launch Greenpeace and participated in some of the environmental movement’s most famous early campaigns, from confronting nuclear weapons testing to putting himself between whalers and their targets. But after 15 years with the organization, Moore walked away.
In this presentation, Moore explains why he believes Greenpeace abandoned its original humanitarian mission, became increasingly hostile toward modern civilization, and embraced what he argues is bad science in the name of environmental activism. He also takes on claims surrounding CO₂, global temperatures, wildfires, forests, fossil fuels, and the long-term history of Earth’s climate.
Then, astrophysicist Willie Soon joins the program for a deep dive into some of the biggest questions in climate science.
How much influence does the Sun have on Earth's climate? How reliable are modern temperature records? What role does the urban heat island effect play? And is the influence of carbon dioxide being overstated by climate models and the IPCC?
Soon discusses decades of research into the Sun-climate connection, solar variability, rural versus urban temperature records, climate sensitivity, and evidence of solar fingerprints in historical climate data from around the world. He also explains why he believes mainstream climate assessments have downplayed important natural drivers of climate change.
It's a different format for The Climate Realism Show this week, but one packed with science, history, and challenges to some of the most widely repeated claims in the climate debate.
Join the conversation in the comments and let us know: What do you think is the biggest climate myth that deserves more scrutiny?
The Climate Realism Show is produced by The Heartland Institute and brings together scientists, researchers, and policy experts to examine the climate stories and claims dominating the news.
