Episode 46: Science Under Siege — Michael Mann and Peter Hotez on the War Against Truth

In this episode of Miles to Go, Miles O'Brien speaks with climate scientist Michael Mann and vaccine researcher Peter Hotez — two scientists who have endured personal attacks, threats, and political smears for standing up for evidence-based truth. Their new book, Science Under Siege, exposes the powerful alliance of plutocrats, petrostates, propagandists, and politicians working to dismantle trust in science — and, increasingly, the institutions that sustain it.

Mann, creator of the famed "hockey stick" graph, recounts how fossil fuel interests and their media allies targeted him for revealing the reality of human-driven climate change. Hotez, co-developer of low-cost vaccines and a leading public-health voice during the pandemic, shares his experiences of online harassment and political intimidation.

Together, they draw a chilling parallel between the denial of climate science and the anti-vaccine movement, revealing how both are fueled by ideology, greed, and misinformation — and now emboldened by government efforts to defund and demoralize the nation's scientific agencies, from the NIH to NASA.

Miles explores the broader stakes of this "war on truth": what happens to democracy when science itself becomes a partisan target — and how, despite it all, urgency still comes with agency.
