This week we talk to Michael Mann who is a professor of atmospheric science at Penn State University. He and his co-authors were the author of the original hockey stick paper and graph where you could see Over hundreds of years how the earth's temperature had been more or less static and then was zooming up in recent times The so-called hockey stick graph that got him the ire of all sorts of well-financed opposition people But honestly we spend most of our time in this episode talking about the science Mike was actually a physics Undergraduate major and so he knows I'm a physicist So we dig in a little bit to the physics of how the Earth's climate is changingHow we know that
We had our fun last week, exploring how progress in renewable energy and electric vehicles may help us combat encroaching climate change. This week we’re being a bit more hard-nosed, taking a look at what’s currently happening to our climate. Michael Mann is one of the world’s leading climate scientists, and also a dedicated advocate for improved public understanding of the issues. It was his research with Raymond Bradley and Malcolm Hughes that introduced the “hockey stick” graph, showing how global temperatures have increased rapidly compared to historical averages. We dig a bit into the physics behind the greenhouse effect, the methods that are used to reconstruct temperatures in the past, how the climate has consistently been heating up faster than the average models would have predicted, and the relationship between climate change and extreme weather events. Happily even this conversation is not completely pessimistic — if we take sufficiently strong action now, there’s still time to avert the worst possible future catastrophe.
