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.

We'll win if we mitigate global warming to.1.5°C. I don't see Biden phasing out coal and fossil gas or setting lowered targets for oil. No, as it is, we will exceed 2.0°C.

He doesn't set targets for any of them. Full phase-out won't happen in his term, but Biden did set a policy of gradually ending them:

This can reasonably be said to be part of it.

Sure, so has almost every country in the world. Men are words, and words are wind.

He has gone through with a pile of policies which to try and achieve that though, and US emissions are falling.

Not falling fast enough, not falling for 1.5°C. Don’t do PR for presidents who don’t give two shits about reaching climate goals.

Definitely not enough for 1.5C; whether recent policy changes get it to fall fast enough for 2C is an open question. They might if we can keep them in place after the election and the rest of the world joins in.

Anything less than 1.5°C is defeatism and is literally the end of the world as we know it. It will literally mean mass death. I won’t settle for a 2°C target.

I'll be fighting for every fraction of a degree, but I don't seriously expect to pull off 1.5C seeing as we're likely to pass that point permanently within the next couple years

@silence7 @mambabasa east coast US & Europe better get ready for AMOC to be shutting down as early as 2025. Florida gonna turn blue despite the red MAGAhats.
