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.

There is a massive issue with adjusting for trade though. If you just imagine a country lets call it Green, which has no emissions, and a another country Black, which is fully run on dirty fossil fuels. Now when both countries trade, the Green country imports emissions and the Black ones are lowered. It can be that dirty processes have been outsourced to the Black country or you can just have the Green country do things better.

When you take the EU and China you can see both. There are absolutely dirty processes outsourced to China, but at the same time things like electricity are dirtier in China then in the EU.
