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.

Realistically the rubber will need to meet the road at some point, and the wasteful alfalfa and almond farmers need to be cut off straight up, because there's no way a handful of wealthy farmers is going to be prioritized over a city of hundreds of thousands if that city is seriously considering trucking in water.

It's like the Irish potato famine - Ireland had the output to support themselves. You'd think capitalism would bow to survival - but it doesn't

Will we cut off exports to keep people alive? The people with money won't.

The rubber has met the road. Physics has caught up with creative accounting. If we don't act now, will we act when people start dying?
