Every now and then an article comes along that takes such a novel approach to an issue, I feel like I’’m seeing something with new eyes. Such was the case when I read Bill McKibben’s 2012 Rolling Stone article, “Global Warming’s Terrifying New Math.” It made me see our climate predicament with such clarity that I knew immediately I had to figure out how to turn this article into a curriculum.

The “terrifying new math” is pretty simple. McKibben, the founder of 350.org and the world’s most prominent climate campaigner, proposes that there are just three numbers that we need to pay attention to in order to reach some radical conclusions about the future of fossil fuels.

The first number is two degrees Celsius, or about 3.6 degrees Fahrenheit. In the 2009 Copenhagen Climate Accord, 167 countries, including the United States, pledged that “deep cuts in global [greenhouse gas] emissions are required . . . so as to hold the increase in global temperature below two degrees Celsius.” The Copenhagen Accord was a timid, inadequate document. According to McKibben, even a two-degree rise in global temperatures is fraught with danger, but it’ is the only international consensus on a climate target, —“the bottomest of bottom lines,” he writes. The first scary number.
