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.

This oil and gas crisis is the best advertisement for renewables ever. We still barely feel the impact of how unprecedented the supply shortage because renewables soften the blow tremendously. 20 years ago a crisis like this would've ended entire states within weeks and throw half the globe into a deep depression.

Now? Now it's somewhere between very inconvenient and extremely uncomfortable. Ironically I think this is also why so many people don't take the situation serious enough. Like "Oh, even if there's an unprecedented oil crisis it's not that bad! See? Importing oil works!" Some people just never learn, I guess. But the economy will respond and bet even harder on renewables. It's inevitable.
