Modern Warming Compared to P-T Mass Extinction

Climate Brief has this graph from Climate Town:

That's quite startling, to say the least; it's downright frightening, to say the most. 

I don't know exactly where the blue line is at the "present"-- maybe 0.03°C? So we've warmed about 50 times faster than the worst extinction event in Earth's history, the Permian-Triassic Mass Extinction which ended about 90% of species on Earth. 

National Geographic:

...the greatest natural disaster in Earth's history. About 250 million years ago, at the end of the Permian period, something killed some 90 percent of the planet's species. Less than 5 percent of the animal species in the seas survived. On land less than a third of the large animal species made it. Nearly all the trees died.

Trump is probably too stupid to understand this. But I really don't think he would care if he did. Not one bit.
