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 know this is a very minor side point to your comment but think the anger against ACs is misdirected. They're electric, and are as clean as the underlying grid. With heat waves becoming deadlier every year, I really can't blame anyone for relying on ACs

I've never used an AC in my home. I live in Southern Europe in an old farmhouse. When it gets too hot I take breaks more often and sit under a tree. I can understand the use in certain contexts like hospitals, certain workplaces, but in general we should employ landscaping solutions and architectural solutions (and even social solutions like normalizing a three hour lunch break) before we normalize using a machine that produces heat in order to fight heat.
