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 absolutely will not. It's become abundantly clear that any sort of actually meaningful climate action will simply not happen in the current system, which is focused on profit at all costs and run by literal psychopaths. We'll continue seeing cosmetic consumer-facing restrictions like the ban on plastic straws that ultimately are nearly pointless in the grand scheme of things โ€“ the real polluters are corporations and people that are much too rich (ie. powerful) for their contribution to this climate clusterfuck to be meaningfully regulated.

For actual change that's not just tiny incremental and ineffectual bullshit that mainly places the blame on consumers, we'd have to redo our entire economic system and that's not going to happen without a lot of bloodshed.
