This isn't news to top climate scientists around the world (see Hadley Center: «Catastrophic» 5 — 7 °C warming by 2100 on current emissions path) or even to top climate scientists in this country (see US Geological
Survey stunner: Sea - level rise in 2100 will likely «substantially exceed» IPCC projections, SW faces «permanent drying») and certainly not to people who follow the scientific literature, like Climate Progress readers (see Study: Water - vapor
feedback is «strong and positive,» so we face «warming of several
degrees Celsius»).
