As world leaders discuss the planet's future at COP26 in Glasgow, climate change remains a massive challenge and a source of fierce debate. While two-thirds of Americans think that the government should be doing more, it's tempting to throw our hands up in despair and think: "There's nothing I can do."

Climate scientist Katharine Hayhoe begs to differ. She says the most important thing is to talk about it—and she wants to teach us how. In this episode, we discuss her hopeful, passionate case for enacting positive change from the ground up, and the finding of her new book, "Saving Us: A Climate Scientist's Case for Hope and Healing in a Divided World."

Katharine shares the science of climate change, how to talk about it across the political divide, and personal stories about engaging highly skeptical audiences, such as when she spoke to a crowd of conservative business leaders in West Texas at a meeting of Rotarians. The outcome was remarkable!

"If we want to change the system, the most important thing any of us can do is to use our voice to influence others to talk about why it matters, and what we can do together to fix it," Katharine tells us. "Wherever we are, we have a shadow not just a footprint, and our shadow can influence people to do things themselves too."

Katharine Hayhoe is the Chief Scientist for The Nature Conservancy and a professor of political science and public law at Texas Tech University. She is also a well-known science communicator, principal investigator for the Department of Interior’s South-Central Climate Adaptation Science Center and the National Science Foundation’s Global Infrastructure Climate Network. Her research currently focuses on establishing a scientific basis for assessing the regional to local-scale impacts of climate change on human systems and the natural environment.

Recommendation: Jim listens frequently to "The National Review" podcast. The latest episode, "An Astonishing Night in Va." is a conservative take on the 2021 election results.
