Ask Lemmy

Yes. I am friends with ecological scientists, biologists, soil scientists, ornithologists, and other various environmental researchers. The rest of my natural life would be ~40-50 years. We probably have 10-20 at most. Remember, the heating is exponential and delayed, and we've also exceeded several other planetary boundaries. Our governments are decades too late. We are literally already in the middle of an extinction event.

Even if everyone TODAY stopped burning all fossil fuels, we'd still have to sequester millions of tons of carbon in 10-20 years with no infrastructure for it. To do this will release more greenhouse gases. Amd we still have to address the 9 other planetary boundaries we've crossed including ocean acidification, soil destruction, and pollution.

The absolute best shot we have is to deflect a percentage of the sun's rays from ever reaching earth with some kind of space blanket or shield. Likely we will just inject sulfur into the atmosphere with unknown consequences.

That you don't realize how bad it is, is the sadder thing. We have seriously failed in educating people about science. Chemical reactions need specific energy requirements to work, which means specific temperatures. It's a big deal to our very cells themselves that the planet is getting hotter. And again, that is only 1 planetary boundary and we have crossed others.

You can literally see footage online of people's housing falling into the ocean, and their property wasn't oceanfront when they bought it. You can look u0 articles about billions of sea life boiling alive off the oregon coast and baby eagles flinging themselves from their nests to die due to heat. You can see the recent article about Dubai being beyond the wet bulb temp for humans to survive. That's not normal, ya'll. None of this is normal.

But whatever, it's too late. Enjoy your remaining years as much as you can, and don't forget you can always starve yourself to death for free if you don't have a bullet. Good luck everyone.

I'm not suicidal.

I am educated in science and I do not think humanity will survive, no. Most megafauna will probably die out. There are ~10 planetary boundaries and we've crossed a lot of them. Earthquakes and volcanoes will start picking up. AMOC collapse could be as soon as 2025.

Depends on the rapidity of the onset of the negative effects of climate change. If it’s slow, we’re gonna lose a lot of people, but we’ll be able to preserve some form of civilization. The worst affected will be the usual poorer people and those who can’t geographically escape the heat for whatever reason.

Worst scenario is rapid onset that disrupts the global network of food, energy, manufacturing, medicines, materials, etc. that literally keep everything working. If that goes tits up in an uncontrolled way just plan on losing a very significant chunk of the world’s population very fast. At a certain tipping point we also lose the people that know how to make things work. Modern society works because we have the ability to free some people from manual labor and subsistence existence to take on highly specialized learning. From fixing the grid, to doctors, to IT specialists, to the academics that teach these specialists. Lose enough of them and you lose the knowledge of how to do anything that makes modern civilization work.

So it all depends on your views if you think you’ll make it to old age. Do you think the world will collapse quickly or will it be a controlled descent? It certainly doesn’t look like we’re going to solve a damn thing regarding anthropogenic climate change, much less reverse anything, and we’re already stuck facing the damaging climate changes we started.
