Rolling Stone: Only 565 gigatons of CO2 until global temps exceed 2-degree limit

That’s about a 15 years worth of emissions at the current global pace. BTW, the 2-degree “goal” is arbitrary.

“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. (“Reasonable,” in this case, means four chances in five, or somewhat worse odds than playing Russian roulette with a six-shooter.) This idea of a global “carbon budget” emerged about a decade ago, as scientists began to calculate how much oil, coal and gas could still safely be burned. Since we’ve increased the Earth’s temperature by 0.8 degrees so far, we’re currently less than halfway to the target. But, in fact, computer models calculate that even if we stopped increasing CO2 now, the temperature would likely still rise another 0.8 degrees, as previously released carbon continues to overheat the atmosphere. That means we’re already three-quarters of the way to the two-degree target. [Rolling Stone]

  1. I have little interest in this article for two reasons: Bill McKibben wrote it, and it appeared in Rolling Stone in July of 2012. It was written by an idiot and it is old news.
