In case you don’t know – these are not survivable temperatures for humanity – or anything else. These temperatures will trigger irreversible feedbacks causing massive die-off and extinctions. We (humans) die of starvation and drought, the rest of the biosphere does the same (heat stress).
Note the rapid acceleration of temperature increase once the 1c threshold was passed around the year 2000 (16 years ago).
This estimate was updated (and will be done again and again) for a projection to the year 2100, however it will very likely all occur long before then (2030). Many of the claims in the linked article are already woefully out of date (also ignore the hopium, we already know that the Paris agreement is a fraud).
Extinction is closer then you may think.
