Carbon dioxide has reached 415 ppm. What is interesting is that Exxon calculated back in 1982 (37 years ago) with great accuracy how much the CO2 concentration and temperature increase will be. Of course, it was unpublished internal research - and this while publicly available science (equally accurate) struggled, without success, to produce political effects. It is still not successful in 2019, not only because of Big Oil's propaganda (this is the scandalous cause that gives good media attention) but because science has an absolutely minor role in organizing society and in political decision-mankind. More Exxon science, you ask? For 2080: 620 ppm and +3.2°C. And - game over. Exxon did not even calculate post-2080.
