Fish can't adapt to temperatures rising that much that fast, neither can the plant life that recycles our oxygen. We ourselves are running out of drinking water even as the people making decisions for us have decided to irrigate our crops with fracking waste water. Maybe its a good thing peak oil is here because fossil fuel use has been part of the problem and changing over to solar and wind might have been good if we had done it in time, but Methane releases are now on the order of 1000 times more damaging even than all that CO2 from cars.
The result is the California drought extending up into Canada and the Canadian fires which may themselves be both releasing and fueled by a self reinforcing methane release loop.
In the Persian Gulf we get heat indexes in the 170 plus range with a combination of desert heat , ocean humidity and direct sunlight
I wish I had a big enough voice that I could stand on a soapbox someplace and make the point that as temperature rises so do sea levels, maybe 5-9 meters in our now much shorter than expected lifetimes. Then there are the 400 some odd nuclear reactors that require maintenance they won't be getting when our cities sink beneath the waves. On top of that there may be many more storms with huge rogue waves of up to 30 meters making life on the oceans interesting. There are a lot of things that can kill us as individuals, but this is the first time its become really obvious the decision making about our imminent extinction as a species that is one component of all the life on this planet has been taken out of our hands.
