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.

hard pushes against combustion engine cars have not happend in the US,

The IRA is a big push for electric and that is definitely being felt across the pond. California has also started to require electric delivery trucks, etc. There is a heavy focus on industry politics rather than improving people's lives though.

whereas both China

Unfortunately, a lot of the electric cars in China so far are likely just additional cars. While there is a definite benefit from this vs. the Chinese buying a ton of new ICE cars, I am not sure those new cars actually work to lower emissions/fossil fuel demand.

and the EU have already passed phase out laws.

The EU was planning to stop the sale of new ICE cars in 2027, but conservatives made sure the date was 2035. And the German (neo-)"liberal" party successfully lobbied for the approval of e-fuel-only ICE cars.

So yeah, a mixed bag. Personally, I am optimistic we'll arrive in a post-fossil economy. I am less optimistic about the timing of it.

Once you stop the sale of new fossil fuel powered cars, you can just wait until the old ones will be scrapped, break down or crash. Especially new cars are almost impossible to fix without proper spare parts, which will become hard to buy once production stops. I know some folks lve their old cars, but that is not going to really support the current scale of the oil industry at all.
