Climate Desk has obtained a leaked copy of the draft Intergovernmental Panel on Climate Change’s 2013 Summary for Policymakers report, which other media outlets are also reporting on. The document is dated June 7, 2013. We recognize, as we’ve previously reported, that this document is not final, and is in fact certain to change.
Most media outlets are focusing on the document’s conclusion that it is now “extremely likely”—or, 95 percent certain—that humans are behind much of the global warming seen over the last six decades. But there is much more of note about the document—for instance, the way it doesn’t hold back. It says, very bluntly, just how bad global warming is going to be. It gives a sense of irreversibility, of scale…and, of direness.
In particular, here are five “holy crap” statements from the new draft report:
We’re on course to change the planet in a way “unprecedented in hundreds to thousands of years.” This is a general statement in the draft report about the consequences of continued greenhouse gas emissions “at or above current rates.” Unprecedented changes will sweep across planetary systems, ranging from sea level to the acidification of the ocean.
