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.

Ugh, States rights? How the fuck do their constituents not see the doublespeak?

K, are they gonna send the military to California bcz that's the only way this is enforceable, then again, California could just not pay taxes, they are the 5th largest economy in rhe world. So, they aren't exactly defenseless.

This comment fascinates me

California is apparently about 12% of the total tax revenue of the US, and New York is about 8%. If every other state was equal after that, they are about 1.5 each.

That's quite a lot of leverage

Can't send people to El Salvador if you can't pay for planes

Didn't the manager for the Patriots lend his private plane to deport people to Guantanamo? Lack of government funded airplanes won't stop them

[–] Dudewitbow@lemmy.zip 3 points 1 month ago

iirc the Patriots plane has a 3rd party management that manages a bunch of planes that happens to also include the patriots plane.

then again, California could just not pay taxes

Income taxes are paid directly to the Federal government. They do not pass through the states first, and thus California can't "just not pay taxes" by an act of government fiat. It would have to convince all of its taxpayers to individually stop.

Doesn’t take much to convince me not to pay taxes

Just gradually increase fuel taxes and registration costs.

[–] Cort@lemmy.world 10 points 1 month ago

Or they could flat out deny registrations for any and all gas vehicles

Almost all the nasty things Trump has done appear to be flouting laws. Good thing he has indemnity.

States rights!

Except when it conflicts with whatever unscientific garbage narrative the dictator is pushing.

California should leave the Union
