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.

If the nuclear industry is going to be quadrupled, and gas and oil are similarly enlarged, and renewables are at least not shrinking, what are people supposed to do with all that extra power in such a short time? I mean, I get that induced demand is a thing but... a quadrupling of long-standing industries? Is there any intention for this plan to be realistic?

Feed the hungry AI, I guess?

If you even get a doubling of power usage that way, I'd be surprised.

One AI datacenter will soon take up the same electricity as a city if we let tech bros keep building.

Instead of admitting the tech has hit a wall they will burn the planet down for diminishing returns on this scam
