What I see in tat chart is that there was a flat period from 50s to 75 (no hydrocarbons burned tn?), they arbitrarily start in 1880, the last 16 years have been flat. And total change is 1 degree, which even by teir own projections does very little over the next 100 years.
This could just as well be a peak. They better get their grant money quick.
