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.

It was 70 last week. And then it dropped overnight to 35. My buddy says "so much for global warming huh?" like it wasn't just 70 fucking degrees out for a week in the middle of winter.

Feb the recorded temp at my house was -13F (-25C ish). March 8th was 77F (HotC). Kind of wild.

Yeah, I was working on getting the AC units working again and my twin was just "Don't worry, it's going to snow tomorrow" (well, a few days ago now) and I just was like. Hell. It's hell.

Yeah, it's going to be 80 near me. Last year it was snowing in March here.

We barely had a winter here in NM. And, it looks like we're about to skip Spring, 90F is forecast for next week. We don't usually see that until May.

Looks like the Salt Lake, other bodies of water like Lake Okeechobee in Florida or the Salton Sea are the same color.

Part of me feels dumb as fuck but I'm going to blame this one on the map makers' color choices
