I was shocked when I first saw their computer-generated outlines of the future. Our carbon dioxide emissions will peak during the next few centuries, then pivot sharply from a "climate whiplash" phase into long-term cooling mode. And I mean truly LONG-term... the last dregs of our carbon fumes will hang around in the atmosphere for tens of thousands of years, and possibly for as long as half a million years depending on how much coal we end up burning in the next century or two.
Up until I saw these findings, my view of the climatic future was mainly informed by charts that ran from the present until 2100 AD, as is still the case for most folks. But the deep future of our fossil fuel pollution is truly immense, long enough to interfere with future Ice Age cycles.
