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'm familiar with all of that. I spent a lot of time on /r/collapse until it went completely off the rails. Crop data is available online - output in Asia is still increasing. I'm not sure if you looked at my sources but outside of social media that horrific doom narrative is not prevalent.

You know how we had SARS, and bird flu, and swine flu, and MERS? And every time scientists rang the alarm bell, but it turned out to not be a big deal? It's because they knew COVID was inevitable - they knew the sketchy meat markets were a huge vector for a coronavirus to cross the species barrier.

COVID could've been much worse, but it certainly affected everyone. It also probably could have been prevented, or at least delayed

These smaller, regional problems are warning signs. A lot of people are dying from them already, but if we don't take them seriously they're just going to get big enough to have global effects. Not in the next century, in the next decade

Are we going to go extinct from climate change? I don't think so. Are you going to die from climate change? Probably not. Will someone you know die from it? Possibly. Will it negatively impact your life? Absolutely, it already has, and it will keep doing so in interestingly obvious ways
