Six Degrees of Change

So what happens if we can’t keep the temperature increases below two degrees? What does that do to the planet?

Bill McKibben wrote an article about the terrible new math of the environment. Most scientists agree that deep cuts in global emissions are required… so as to hold the increase in global temperature below two degrees Celsius. Scientists estimate that humans can pour roughly 565 more gigatons of carbon dioxide into the atmosphere by midcentury and still have some reasonable hope of staying below two degrees. The amount of carbon already contained in the proven coal and oil and gas reserves of the fossil-fuel companies, and the countries (think Venezuela or Kuwait) that act like fossil-fuel companies. In short, it’s the fossil fuel we’re currently planning to burn. And the key point is that this new number – 2,795 – is higher than 565. Five times higher.

McKibben had estimated leaving 79.8 percent of the fossil fuels in the ground (565 gigatons divided by 2,795 gigatons)—a daunting challenge of math, policy and politics. The IPCC’s new math is even more terrifying: 469 gigatons divided by 3,000 gigatons, or 84.3 percent of the world’s fossil fuels need to remain forever untouched.
