This is an incorrect way to frame the impacts of temperature increases. 1.5, 2, 3C makes extreme events like the one you stated significantly more likely in a probabilistic sense. The ability of adapt is in part driven by frequency of extreme events as much as it is adaptability to specific thresholds. We are already experiencing deadly heat bulb events at current warming levels, the impacted areas and frequency of these events will strictly increase.
replyI agree, but what we aren't currently really seeing (at least I've not seen it) is a heat dome killing off a herd of cattle or a crop.
replyThat's the sort of event that becomes much more likely if not inevitable as the temperatures increase.

replyWell that's a relief, glad I am a turtle then and so are most of my friends, and that our whole world economy and food system runs on turtles. So we should be fine.
replyYou are right, it is an exaggeration.
replyI should have said "land life" as the ocean temperature doesn't shift that much with the above ocean temps.
And I'm sure there's some random bacteria and fungus that can survive and thrive at 40C web bulb.
What doesn't tend to do so well is the likes of humans, birds, cattle, horses, mice, rats, insects, many crops, native animal life that didn't evolve to handle high heat temperatures.
The last time earth will have been as hot as the 3C temperature was prehistorically.
I wonder if "but the turtles survived and I was right!" is the best way to look at it if humanity is close to extinction in the next century or so.
reply…and from here, it’s turtles all the way down.
replyYes for temperature but what about CO2 ppm?
replyTemperature will kill most things before CO2 does. Current CO2 levels are making humans slightly stupider, but politics is doing that a lot more.
replySo ... It's turtles all the way down?
