And the world doesn't end in 2100, even if our scenarios used to. AR7 will extend projections through 2150. As long as CO2 emissions are above zero, warming continues. The high scenario eventually catches up to RCP8.5-level warming, just later. Even the medium scenario ends up at 3.7C:

A tripling of emissions by 2100 was probably never plausible. But a doubling was. The fact that we're no longer on that path is real progress — not, as some pundits claim, an indictment of climate science. And we still have a long way to go get emissions to zero and stabilize global temperatures.
