Climate - truthful information about climate, related activism and politics.

Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

How can you be uplifted and protected from starvation when ecosystems completely collapse? There will be no cattle farming, no agriculture. If climate change is as disastrous as scientists warn if we don't change there will be nothing to uphold them with. The masses will quickly consume their masters and then each other as we return to tribes. The most the rich can hope to do from their bunkers is scavenge for substance as the last is swallowed by the flies. They just don't realize they're building their own tombs.

How can you be uplifted and protected from starvation when ecosystems completely collapse?

The same way humans always have, by adapting to change. Yeast and bug protein powder, skyscraper farms and bioreactor grown meat.

Humans would likely survive on a completely sterile planet at this point, science is so advanced. But it would not be enough for 8 billion people, so a lot of forgotten and poor people will suffer.

If climate change is as disastrous as scientists warn if we don't change there will be nothing to uphold them with.

Scientists have already figured out where the disasters will be concentrated, and the wealthy have already prepared themselves, governments included.

The doomer idea that the entire planet will become unlivable is just nonsense. There will be many shitty places to live where the heat will kill thousands every summer, or the weather becomes too extreme for stability.

But there will also be lots of places that just get more rain than they’d like. So once again, the poor and inequitably treated will die and suffer. Starting to notice a pattern yet?

The masses will quickly consume their masters and then each other as we return to tribes. The most the rich can hope to do from their bunkers is scavenge for substance as the last is swallowed by the flies. They just don't realize they're building their own tombs.

If you’re just seriously sitting around expecting society to collapse to solve this problem then you’ve already lost.

I dont think you understand. There will be no supply chains to make these advanced materials. If we aren't doing it right now, it won't be here when the climate collapses. There will be no bug farm paste manufactorums. There will be no steel mills. You can't have skyscrapers when there are no supply chains producing steel to support the buildings, plus all the machinery to actually piece together the building. Construction will immediately be shot back to the dark ages or prior. Because it too relies on advanced global supply chains to acquire the materials to make the advanced materials to construct infastructure with.

I should also note we are on the hypothetical of complete collapse. We are already arguing in that context, I'm not actually waiting around like its a fact. But the billionaires are, they're building their bunkers expecting to make it (?) to some unknown date where the surface world is magically habitable again.

Yes, none of that is going to happen, thankfully.

It’s just going to result in more powerful storms and extreme weather spread throughout the planet.

Lots of life will die off but it will be absolutely nothing compared to the shit our planet has seen in the past and recovered from.

In the end, we're killing ourselves and the things we are familiar with. The things that make Earth, to us. I hope the squids have a better run than we did.

Lots of good people working against it as well.
