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.

Even the top of the line gaming PC's hardly draw 750w under full load, mine is pretty much the maxed out Gen4 and running stable diffusion will put it at 575w at absolute most, and that's including my monitor and peripherals (speakers w/ subwoofer, USB etc). Normal gaming will vary, 2077 pushes it to the 450w range sometimes but not much. And even then, I'm gaming for maybe 3 hours at most?

If I were running Stable Diffusion over night, that's one thing and it would definitely get my room to 90F. But a few hours gaming, even 8+ hours isn't too much to account for, especially if it's used to offset other costs - for example using an electric heater/radiator that draws 1500w and has no other use other than providing temporary heat.

I also think we have plenty of ways to game with low power if the mobile PC market is anything to go by. We don't necessarily need 3080-4090's drawing 500w for their full loads. Especially if we adopted other means of powering our grid, at that point it's only an issue of the heat generation, which is sort of a necessity anyway so if we're going this way then we may as well build homes with PC generated heating in mind! (\s but maybe lets do it?)
