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.

A lot of the laws passed are still going strong. ETS-2 which is a carbon trading scheme for transport and heating should start 2026. The law has passed, so that is pretty safe. The ban on sales of new fossil fuel cars is going to start in 2035, so that needs preparations as well. Also the number of ETS-1 certificates has been lowered. That is basicly the EU level stuff, which has some real impact and has been passed since the gas turn off. Those are going to take some time to really work.

Honestly at the moment permitting large fossil fuel projects in the US to help the EU are imho just fossil fuel propaganda.
