When it comes to climate change, this truly is a golden age—of fake news, post-truths, pluralistic ignorance, conspiracy theories, a willfully ignorant administration, and the Cranky Uncle. You know him. We all have one. That exasperating Thanksgiving blusterer digs in his heels even as the foundation of his denial thaws faster than the Arctic ice caps. Written and illustrated by Dr. John Cook, cognitive psychologist and founder of the award-winning website Skeptical Science, combines humor and science to make clear, calm, and winnable arguments in the public controversy of climate change. Can we change our Cranky Uncle’s mind? Probably, regrettably, not. But Dr. Cook makes it easier for us to understand him. And armed with this knowledge, prevent climate misinformation from spreading further.
