I am terrified of climate change (self.chat)

I'll keep this short and sweet. Some random guy on the internet compiled together and summarized a bunch of climate research papers analyzing global trends and a bunch of different slow actors that are all going to kick in soon like the permafrost in Russia or the polar ice caps etc.

While I have not yet gone through the sources the author links and quotes extensively, this still has me extremely worried and I think that unless society somehow drastically changes and devotes a significant effort in doing something about it, we're all going to die within half a century.

I'm sorry for bringing doomerism into a safe space like Beehaw, but I'm scared and I can't sleep.

Also I'm not going to link the document in question because the author goes on a rant about billionaires and greed, and while I haven't decided whether or not I agree I'm not sure the tone fits the community.

Sorry again and have a good one !

The concerning part is that a lot of the data is the most conservative available, so as to not seem alarmist. When even that looks grim, it's hard to hold onto any hope that our planet is on track to becoming anything other than a hellscape. A lot of climate change is the result of positive feedback loops -- self-aggrivating conditions. E.g., warmer arctic climate causes the release of methane previously trapped by ice (methane is a ridiculously potent greenhouse gas... something like 30x more potent than CO₂), so its release causes the climate to warm even more, which melts more arctic ice, which releases more methane, which makes the climate warmer, which melts more arctic ice, etc...

Even if every human just suddenly got thanos-snapped out of existence right now -- no more cars, no more shipping, no more deforestation, no more industry of any kind... full stop on pollution and active environmental destruction... even then, the positive feedback loops we've set into motion aren't just going to stop on their own. The process would be slower, sure, but Earth is (rather, the things on earth that make it more than just a dead rock floating in space, are) fucked.

On the plus side, we'll only be alive long enough to see the start of the 'find out' era. It's the generation after you that's really fucked; and the generation after them that's really, REALLY fucked, rinse and repeat until humanity is an eco-dome filled with oligarchs, or just straight up extinct.

At this point we're dependent on a (series of) miracle-tier scientific breakthrough(s), or literal divine/extraterrestrial intervention. I don't see the latter two happening. Vote for candidates who give a shit about science if you think there's any hope in that route.
