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.

subisdizing fossil fuels during shortage is opposite of reasonable policy. While only path to prevent global warming is carbon tax and dividend, giving people more money during shortages is better policy than subsidies. If it is calculated that average person will face $100 in extra costs due to fuel prices, giving $50 in payroll tax cuts, and $50 cash to everyone is path to compensating both employees forced to get to work, and all people. Whether EVs or bicycles or transit or just paying more for gas for their cars, people are empowered towards solutions that maximize their welfare.

For Germany to triple down on geopolitical extortion energy is a special kind of stupid.
