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.

Or. Crazy concept. We actually stop buying plastic. Stop burning fossil fuels. You know just general common sense kinda stuff.

No, no we wont allow our way of life to be impacted at all. Require the planet to be destroyed so we can drive luxury SUVs to pickup our plastic coating everything.

The classic "here is a magic solution that 'scientists' came up with that is totally doable and not at all meant to just distract you from the real solution that reduces consumrism"

[–] Milksteaks@midwest.social 16 points 10 months ago (1 children)

Woah woah, hold on there. We cant just consume less that would mean the line going downwards and we cant have that. The only solution to this problem is infinite growth and a giant space mirror

Reducing consumerism is pretty meaningless at this point in the game.

Didn't the Simpsons do this already?

Mt Burns did it for purely evil reasons, yes.

We are pursuing both options, and think that if a planetary sunshade is built, the initial phases of construction will be an Earth-launched architecture while the later phases will use space resources and in-space construction

Great, so it's a 50 years plan then. Too bad we can't do anything right now I guess.

Well we could, but it would reduce short-term profits for the wealthiest few hundred sociopaths, so we can't.

This has Snowpiercer vibes.

Still can't believe no-one will release the final season of that show

Or we could do Stratospheric Aerosol Injection, SAI, since we'd have already geoengineered our climate, might just go and engineer it so that the damage can be less. Yeah it's not great since it does not solve the root cause, but it might avert the worst case scenario. The world might one day stop using oil like a junkie, even faster if we globally started to tax carbon emissions, but clearly the world has been kicking the can down the road about meaningful change. Lets accept we have already done way to little already, accept the shit we already are in and make emergency repairs before even more things break down

Once we get the world carbon neutral or negative to deal with ocean acidification, a sunshine might genuinely buy us some time and make up a bit for the lost polar albedo. But cloud seeding would probably be cheaper.

They prefer to create unrealistic "solutions" that look like they came out of a cartoon instead of reforesting and stopping the last stage of savage Capitalism. The only solution is politics
