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.

What will we need all those fossil fuels for? Surely, at some point in the early 2030's, as capex for PV/wind turbines/heat pumps/batteries decreases and opex remains low, most people will have realized that fossil fuels are personally costing them money. The only business remaining may be plastics rather than electricity and heat. Granted, it's entirely possible fossil fuel companies successfully double down on plastics (which is what many are planning already).

I mean, thanks to citizens united and "lobbying", oil companies control the US, and therefore the world. So no, I don't expect to see much change.
