Climate change is demanding an extraordinarily rapid transformation of human society, and we don’t have a manual. The people who have done the least to cause the problem are the people who will be feeling it most, and that pattern of inequality exists both within and between nations. Mapping a course to an adapted planet is an incredibly complex task that requires the cooperation of millions. Atmospheric scientist Katharine Hayhoe is one of those pitching in, and she has co-authored the past four U.S. National Climate Assessment reports. She’s also the chief scientist at The Nature Conservancy and a professor in the Texas Tech University Political Science department. Her multiple insider roles give her a unique perspective on what it will take to solve and adapt to the climate crisis, and her practice of finding hope keeps her engaged. NBC “Today” show weather and feature anchor Al Roker interviews Hayhoe at the 2024 Aspen Ideas: Climate event in Miami Beach, Florida.
