Bill McKibben has an important piece in Rolling Stone about climate change: Global Warming's Terrifying New Math

We probably are having the warmest year ever recorded by science, and one of the warmest years in a couple/few hundred thousand years as recorded by proxyindicators. Bill's piece talks about three "terrifying" numbers: 2 degreec Celsius, 565 Gigatons, and 2795 Gigatons.

And there are other numbers too:

...The week after the Rio conference limped to its conclusion, Arctic sea ice hit the lowest level ever recorded for that date. Last month...Tropical Storm Debby dumped more than 20 inches of rain on Florida – the earliest the season's fourth-named cyclone has ever arrived. ...the largest fire in New Mexico history burned on, and the most destructive fire in Colorado's annals claimed 346 homes in Colorado Springs – breaking a record set the week before in Fort Collins. ...scientists issued a new study concluding that global warming has dramatically increased the likelihood of severe heat and drought – days after a heat wave across the Plains and Midwest broke records that had stood since the Dust Bowl, threatening this year's harvest....In the course of this month, a quadrillion kernels of corn need to pollinate across the grain belt, something they can't do if temperatures remain off the charts.
