There was a flurry of activity at CU Boulder despite the uncharacteristically warm weather Sunday night.
Bill McKibben, an American climate activist, author and journalist was in town for his Do the Math Tour. He’s the founder of the grassroots climate campaign 350.org.
In his traditionally accessible style, McKibben presented three numbers that might add up to global catastrophe.
The numbers, the focal point of his recent Rolling Stone article, “Global Warming’s Terrifying New Math,” are central to his presentation as he tours the country to raise awareness about climate change, encouraging people to take action.
