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.

Excellent article, thanks for sharing.

I hope they do find out what causes it to happen now, and to happen at this pace.

Countermeasures are the obvious ones, of course. People cannot prevent the oceans from doing their thing, but they can stop doing what they're doing to the atmosphere.

For those who want maps and graphs to describe the problem, this site offers a bunch.

Good link, thanks.

I keep saying this, but it feels more and more like we're in the beginning of a black swan event. Solar maximum for this cycle is probably just a couple of years in the future, too, so it'll be interesting (as in "may you live in interesting times" interesting) to see how that affects things

Yeah we're so fucked. Already its gotten so much worse so much faster than even the biggest doomsayers predicted. I expect we're right at the turning point and things are just gonna get exponentially worse. How we've known about this for like 60 years and not done anything to minimize the effect just makes me feel like we deserve to go. I wish it could just be the billionaires but they're dead set on taking the rest of us with them. (Or they think they can ride it out in fancy bunkers, fucking idiotic psychopaths.)

That is how the world works!
