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.

Too optimistic. We are already 15 years past the "3 more years" of the past.

Americans voted for Trump, so we all get to die. Yay.

Wrong. There's always going to be a worse impact. There's no upper bound to how bad things can get.

[–] kapulsa@feddit.org 9 points 2 days ago

For humanity, there is. The impact we're facing right now is the end of civilization before the end of the century. The impact we're facing if we don't act within 3 years is extinction. The speed of these impacts may vary slightly, though.

By Tuesday...

So, are we going to organise a general strike to enforce change or should we start preparing for a different climate?

[–] ProdigalFrog@slrpnk.net 17 points 2 days ago* (last edited 2 days ago)

Currently a general strike in the US is planned for May 1st 2028 to coincide with the UAW's contract ending. Unfortunately that's 3 years away, and I doubt climate policy is going to be a focus of that strike.

Hopefully we can organize one sooner, but we'll see. Syndicalist unions independent of corporate control would be the most likely to initiate a general strike, so I'd recommend joining up and unionizing your job with them if you can.

I also hope the rest of the world pushes for their own general strikes.

The latter while hoping for the former

Well then brace for impact I guess, because we know we aren't going to change how we do things much in the next 5 years.

Sooooo build a bunker and hoard guns and ammo, then?

[–] Tiresia@slrpnk.net 5 points 1 day ago

What do you plan to do with a hoard of guns and ammo? Get yourself killed so people can loot your bunker?

[–] x00z@lemmy.world 12 points 2 days ago (1 children)

You would think even the most selfish politicians and CEOs have already experienced some extreme events at this point.

[–] DriftingLynx@lemmy.ca 13 points 2 days ago (3 children)

They will be safe in their air conditioned, walled, armed guarded, coal powered compounds. The rest of us are expendable to them.

[–] Thedogdrinkscoffee@lemmy.ca 7 points 2 days ago (1 children)

No one is safe. All will suffer on a dying planet.

[–] CalipherJones@lemmy.world 4 points 2 days ago

The Global South will be the ones to take on the brunt of the suffering, as is tradition.

More than you or I will get 🤷

Well considering they have so much wealth, they can just build their Shangri la on top of Mount Everest or 50 miles below earth, and continue their existence, I'd say indefinitely.

[–] anomnom@sh.itjust.works 4 points 1 day ago* (last edited 1 day ago) (1 children)

Do they have indefinite food stores? Stock values aren’t going to mean much then.

I’m pretty sure that’s why Zuckerberg is trying to own that whole Hawaiian island. He’s still going to need help farming it.

[–] DriftingLynx@lemmy.ca 4 points 1 day ago (1 children)

Once there's no governments to make stuff like pesky anti-slavery laws I'm sure he'll find a way to justify whatever cruelty pleases him.

[–] anomnom@sh.itjust.works 1 points 17 hours ago

He doesn’t have the charisma for that. I’m sure someone does, but communities will be better at survival in that scenario.

[–] x00z@lemmy.world 3 points 2 days ago

Well there's ones that are golfing all the time and laying in the sun on their yachts.

[–] Lucidlethargy@sh.itjust.works 4 points 2 days ago

I've seen this one before. The world will fail.

I've seen this one before from back to the future

I can't wait for a study in 3 years labled "We are doomed"
