Both of these are wrong:
The intent is to show the proportionality between cumulative CO 2 emissions and global surface air temperature in 3
observations and models (left) as well as the assessed range of TCRE and the right-hand panel shows how information 4
is combined to derive remaining carbon budgets consistent with limiting warming to a specific level
3000 Gton corresponds to +26C after 700 years and not +1.5 as the graph on the left suggests. See Most Dangerous
The CO2 budget ended in 1895 when CO2 levels rose above 285 ppm, giving +2C.
We are not going above +1.5 See below
