Global Warming's New Reality 

This year we’ve seen what many experts agree are real symptoms of global warming - from fires in Colorado to drought that now blankets more than 60% of the country. And this July was the hottest ever for those of us in the lower 48. 

Except that it wasn’t just July. The average temperature from last summer to this summer is hotter than any 12 month period on record in the U.S. 

So, what’s going on here? 

We dive into the science - and the politics - with author and activist Bill McKibben and Harvard's Dan Schrag. 

Guests:

• Bill McKibben, activist and author of Global Warming's Terrifying New Math

• Daniel Schrag, Professor of Geology, Environmental Science, and Engineering; Director of the Center for the Environment, Harvard University
