Dr. William Happer Challenges Climate Emergency Claims in Podcast

Dr. William Happer, a prominent American physicist and co-founder of the CO2 Coalition, appeared on the latest episode of the Leighton Smith Podcast on December 3, 2025. During this episode, Happer strongly asserted that there is no climate emergency, urging listeners to reconsider widely held beliefs about climate change. He emphasized that those who believe otherwise have been misled.

Happer’s insights come at a crucial time, particularly in countries where political leaders often promote misguided narratives about climate policies. He criticized the notion of achieving ‘Net Zero’ emissions, arguing that it is based on flawed assumptions. His remarks aim to challenge the prevailing attitudes that often lead to the rejection of scientific discourse.

Throughout the podcast, Happer discussed a range of topics related to climate science and policy, drawing on his extensive experience as an author of over 200 peer-reviewed scientific papers. His views are particularly relevant given the ongoing debate about climate action and its implications for economies worldwide. Happer’s willingness to engage in discussions that are often deemed controversial highlights a gap in the dialogue surrounding climate change.

This perspective is often at odds with mainstream climate narratives, which categorize CO2 as a leading contributor to global warming.

Listeners can also expect a segment titled “The Mailroom,” where Happer interacts with the podcast’s producer, addressing comments and feedback from the audience. This interactive portion adds a personal touch to the discussion, allowing for a more comprehensive exploration of the topics at hand.
