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.

The mastermind behind all this must be building fallout vault-like structures to allow people to survive the planet when all is said and done. They will rule the world in the end, perform experiments, whatever they want.

The timeline for the earth to cool back off is a hundred thousand years. A bit too long to wait out in a bunker.

Not with that attitude

I actually got a long ad on YouTube recently for luxury bunkers equipped with everything to go on for decades no matter what's going on outside. So yeah, that's a business now.

What the hell is a luxury bunker?

Gold plated vault doors? Red carpet? Fancy mini bar soaps?
