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's a bad situation to be in, since there is an immediate geopolitical need not to be dependent on OPEC and Russia, which use the oil market as a weapon of economic warfare, but there is also an immediate need to reduce fossil-fuel consumption. So far, the former has taken priority, though in both the US and the UK, large renewable power generation projects have also been coming online, and in the UK, the new government has committed to further accelerate that build-out.

Neither the US has only a few states with a phase out of fossil fuel vehicles being legally binding. The UK has nothing whatsortever. The EU seems to go for a different startegy with a sales ban in law starting 2035, while many EU countries banned fracking, which could be used to produce a large share of the local oil consumption.
