At this point, the scientists who run the Intergovernmental Panel on Climate Change must feel like it’s time to trade their satellites, their carefully calibrated thermometers and spectrometers, their finely tuned computer models – all of them for a thesaurus. Surely, somewhere, there must be words that will prompt the world’s leaders to act. This week, with the release of their new synthesis report, they are trying the words severe, widespread, and irreversible to describe the effects of climate change – which for scientists, conservative by nature, falls just short of announcing that climate change will produce a zombie apocalypse plus random beheadings plus Ebola. It’s hard to imagine how they will up the language in time for the next big global confab in Paris. But even with all that, this new document – actually a synthesis of three big working group reports released over the last year – almost certainly underestimates the actual severity of the situation. As the Washington Post pointed out this week, past reports have always tried to err on the side of understatement; it’s a particular problem with sea level rise, since the current IPCC document does not even include the finding in May that the great Antarctic ice sheets have begun to melt. (The studies were published after the IPCC’s cutoff date.) - Bill McKibben, The Guardian
