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.

If only we could tax fossil fuels. It wound kill two birds with one stone. Fix the environment and reduce all the AI being added into everything.

Just removing the subsidies would make a big difference

Yah I don't understand how these are multi billion dollar companies and they are still getting subsidies tax breaks handouts whatever form the governments of the world. Like WTF.

It’s not a tax we need, because that just hits the people. We need a need an operation fine and a price cap to prevent them from passing the buck, so to speak. That way it won’t be profitable and they will reinvest someplace else… hopefully solar or just not energy at all.
