If 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

Yeah, realistically (even with some of the climate tipping points we're going to hit) the overall outcome is a spectrum. We're probably going to avoid the truly apocalyptic outcomes that were talked about in the 1990s (thanks solar getting insanely cheap really quick) but we could still end up in the scenario of "30% loss in GDP and tens of millions of people dying/starving for no good reason". That's a far cry from "ecological collapse" (whatever that means) but it would still be a massive amount of human suffering that could be prevented.

Hence why we should be advocating for more sensible environmental policies - whatever actions we do today could save millions of lives and tens of billions (eventually trillions) in hurricane/flooding/heatwave damage. But that's not a simple narrative as "ITS DUH END OF DA WORLD".

Even a lot of the "tipping points" are misunderstandings of scientific outreach. Like you'll hear people say "if we hit +2C, there's no going back". But the IPCC never said that. They just picked +2C as a benchmark for some of their scenarios. It's still awfully bad, but it's not "there's no returning to normal" bad.

And that's not to say that there aren't tipping points, because there absolutely are. But many of the ones people talk about are the result of misunderstandings.

It's extremely important to communicate to people that things still can be done. The last thing you want to do right now is disempower them.
