this is based on rcp8.5 which i think is widely considered pessimistic even for a business as usual emissions scenario

rcp8.5 has us *now* at about 425ppm CO2-equivalent. (Staying under 500 through 2030.) This number, by NOAA, (which may account for short term warming differently, since it doesn't match) seems to say we're currently at close to 500, still accelerating - https://www.esrl.noaa.gov/gmd/aggi/aggi.html …
