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.

Geoengineering our way out of this hole is way more likely to worsen the situation, if the environmental effects of almost every large scale engineering project is checked.

Of course the alternative is changing lifestyle, so fucking up the environment is gonna it I guess.

The real alternative is to restructure our incentives systems (i.e. capital market regulations), but that's the absolute last thing that will ever happen. Carbon taxes are a step in that direction but are still just a tiny bandaid on a gaping wound.

We will darken our skies before we make the needed changes.
