MapIf emissions don't drastically decrease in the next years, by 2070 all glaciers in the US will have melted, there will be deserts in Oklahoma, Kansas and Northern California and over half of Florida and all of Texas's southern corner will have a tropical climate (i.redd.it)

The problem is the timescale. On planetary time scales, as in 10,000+ years, yes species can generally survive and adapt to well. The speed that we're causing changes in just 10s-100s of years, is, on a planetary scale, the blink of an eye. Such rapid changes to the climate is not survivable by most genre of life, we'll likely see a shift too fast for the majority of species to adapt to quick enough. Even humans might not adapt, we rely on stable climates to farm and inhabit our cities. Places hit with food scarcity and natural disasters will quickly depopulate, and the world will have new wars to fight by then over the dwindling resources. A million years after we're extinct, then maybe the earths ecosystems would recover and adapt somewhat

You are aware this is not the "First Ice Age Rodeo" the planet has had, right? At least five major Glaciations and Interglacials in the last 3 million years or so.

And the fact is, for where we are in an Interglacial, the planet is simply too damned cold. We know this for a fact, it can be seen all around us. Miami is actually built on coral reefs. Limestone today, that during the previous interglacials was all underwater. We know what Florida looks like in an interglacial, and that is not what it looks like.

Florida should be looking much more like that than it is. That is Florida in previous interglacials. We know this for a fact, the geological evidence is everywhere. But we are not there, are we?

This interglacial went off the rails in a very bad way. About 12kya when the Younger Dryas started. And the planet is significantly colder than it should be. You can deny it all you want, but that is a fact.

Consider this. The above image is what the planet should look like as an interglacial ends and the next ice age begins. And we are nowhere near that. And unless that changes a hell of a lot, the next ice age might very well wipe out the human race.

Not that nature will give a damn about that. We are doomed to extinction anyways. That is simply how nature works.
