The graphs above show that proven reserves and especially potential carbon reserves are more than 2-4 times as large as the generally accepted carbon budget to hold global warming even to 3°C.* There is no chance (right) of keeping the probability of warming less than 1.5°C below 20%, and only a modest chance (future burning would be only 40% as much as we've burned already) of keeping it below 50%. Burning all our proven carbon reserves is a recipe warming of well over 5°C, which some call a doomsday scenario.
* [this website’s author’s note: The ability to meet a 3°C target neglects positive feedback effects from albedo changes as sulfates in the air are phased out and as sea ice, snow cover, and ice sheets melt and mostly vanish - except for much of East Antarctica. It must be supplemented by removing most CO2 that humans have put in the air.]
