Health in Climate is bringing together clinicians, engineers, technologists, and climate professionals for a two-day hackathon during Climate Week NYC, September 19–20. No coding experience required. This event is built for cross-sector collaboration: you bring the expertise, ideas, and lived experience, and our mentors help turn them into real solutions. Participants will work in cross-sector teams to prototype practical, AI-powered solutions to real climate-health challenges, guided by mentors and subject matter experts from across the health and climate sectors. Winning teams will share $5,000 in cash prizes. This event builds on the momentum of our London Hackathon and continues our mission of accelerating climate-health innovation through collaborative, cross-sector problem solving.
