Bill McKibben's biography

At a glance

  • Pioneering climate writer and author
  • Founder of global grassroots climate campaign 350.org
  • Organizer mobilizing older Americans for climate action
Bill McKibben is a climate writer and organizer whose work over nearly four decades has shaped how the world understands and responds to global warming. McKibben wrote The End of Nature in 1989, the first general-audience book on climate change. He founded 350.org, which grew into the largest grassroots climate campaign on the planet, and later launched Third Act, a movement mobilizing Americans over 60 for progressive action. His value to audiences lies in the rare combination of deep scientific literacy and practical organizing experience. McKibben does not simply describe the crisis; he maps pathways out of it. His latest book, Here Comes the Sun, lays out a concrete case for solar energy as the foundation of a new economic and political order, grounding optimism in data rather than wishful thinking. Audiences leave McKibben's sessions with a clear understanding of where the energy transition stands today, specific strategies for civic engagement regardless of age, and a framework for thinking about climate solutions that balances urgency with achievable action. His track record of building movements from scratch gives his recommendations weight that purely academic speakers cannot match. Book Bill McKibben to give your audience both the full scope of the climate challenge and a credible, energizing plan for what comes next.

Why we recommend booking Bill

McKibben brings four decades of frontline climate organising to the table, translating complex energy transitions into actionable civic strategy rather than abstract policy. His track record building 350.org and Third Act gives him operational credibility that resonates with audiences needing practical pathways beyond the science itself.
