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.

I think we're fucked. Human nature, slow governments, apathy and disbelief mean we will not overcome climate change.

Best brace for the impacts in all practical ways. It will not go away and will only get worse.

I hate being a doomer but yup we're unbelievably fucked. Anyone want to guillotine some rich folk with me on the way out?

I hear that makes the meat taste worse.

Oh boy I can't wait for hard decarbonization. Yee haw.

[–] Bipta@kbin.social 4 points 10 months ago (1 children)

Is that when carbon based life goes extinct?

Yes but only the weird lanky monkeys.

Sadly, I don't think we're the only animals that will disappear.

[–] hotair@slrpnk.net 1 points 10 months ago

What is that? Like, carbon emissions stop because of general supply chain collapse? Or we all get together and figure out a way to make massive diamond blocks from the CO2 in a hurry?

you can 'expand' local production to decrease reliance on foreign sources and still also decrease overall consumption.

[–] MrMakabar@slrpnk.net 2 points 10 months ago

The issue is that especially oil is a globally traded commodity. So increasing local production means you buy less from abroad and that means lower prices, so others are more likely to buy it.

Also the money can be used to invest into green infrastructure as well.

The Russian war of Genocide rejiggered the entire planets energy sourcing, and though we're decades past where renewable energies could, and should have already taken over for Fossil fuels everywhere, the old systems of profit couldn't rejigger themselves quick enough to benefit from the change, and so it's back to fossil fuels, planet be damned

[–] hotair@slrpnk.net 1 points 10 months ago (1 children)

There was a hopeful time when the gas turned off (or the pipleine exploded) and every energy saving project came to the forefront. I hope these efforts are still going on?

A lot of the laws passed are still going strong. ETS-2 which is a carbon trading scheme for transport and heating should start 2026. The law has passed, so that is pretty safe. The ban on sales of new fossil fuel cars is going to start in 2035, so that needs preparations as well. Also the number of ETS-1 certificates has been lowered. That is basicly the EU level stuff, which has some real impact and has been passed since the gas turn off. Those are going to take some time to really work.

Honestly at the moment permitting large fossil fuel projects in the US to help the EU are imho just fossil fuel propaganda.

When you are making very difficult life and death decisions regarding resources for your family, remember your conservative neighbors did this. And they did it gleefully.
