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.

Yes, because despite both being extracted out of the ground, fuel you don't get to keep once spent, while lithium you can!

Coal is becoming super uneconomical for power generation, with a relative abundance of natural gas which itself (talking about the byproducts after burning it for electricity) is far better for the environment and doesn't require a complete overhaul of the boilers. Renewables are becoming cheaper every year so long term, despite Republicans' best efforts to play big government when they feel like it and go against the free market, renewables will proliferate increasing the impact of electric cars over gas. Better transport alternatives like bikes buses and trains are the best way, but EVs are a marginally acceptable alternative for car-brained societies.
