As a climate scientist, I’ve been working on these issues for more than four decades, and my new book, “The Changing Flow of Energy Through the Climate System,” details the causes, feedbacks, and impacts. Let’s take a closer look at how climate change and natural weather patterns like La Niña influence what we’re seeing around the world today.
