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.

This Incredible Tool (preventing insolation) That Our Ancestors Used To Keep Cool In The Summer.

Yeah, they cost money. So does installing air-conditioning. But they use no energy ( that'd would be bad for fossil energy-producers).

Just make me a goddamned hobbit hole that has less need for temperature management.

So, I'm lucky enough to have built a house, and earthworks are expensive. A hobbit hole would cost as much as the house we live in, without the actual building, just the hole.

Yeah, I would have to blast bedrock to make a hole or buy tons of soil to bury a house lol.
