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.

I'll note that the US is a net exporter of oil and of methane gas.

Since Americans can't actually burn the additional extraction, this means more exports, and profits for the owners, rather than some kind of public benefit. So Americans reap all the consequent climate damage, but somebody else gets all the benefit.

Because of "energy emergency", somehow means wind energy must be exterminated, and replaced with more expensive new FF plants. 4x more energy efficient EVs must also be curtailed, and lose their efficiency advantage through FF electricity plants.

Exporting more LNG also means making NG more expensive for Americans.

All of these actions are the opposite that would be taken if a real energy emergency existed.
