Well 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.

You are right, it is an exaggeration.

I 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.

…and from here, it’s turtles all the way down.

Yes for temperature but what about CO2 ppm?

So ... It's turtles all the way down?
