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.

I don't have a console, but I've hooked up a Kill-A-Watt to my crazy gaming PC with a TDP > 600w. When working, browsing, listening to music, watching videos, etc, it only uses around 60w, or the same as a single incandescent light bulb. When playing a modern AAA game, it uses around 250w. Not great considering the power consumption of a Switch or Steam Deck, but orders of magnitude less than typical U.S. household heating and cooling. I'd guess AI and crypto BS uses more energy than all PCs combined. Though I guess we all indirectly use AI (or rather, get used by AI).
