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.

Power demand is surging because of "AI".

[–] spidermanchild@sh.itjust.works 1 points 1 day ago (1 children)

The article says it's primarily increased cooling load since it was hot as shit in 2024, with data centers playing a smaller role. We also have EVs, heat pumps, and growth in the manufacturing sector. Also mostly ignored is the fact that we have physically more people here, mostly due to immigration. Like most issues, it's multifaceted. That being said, AI is bullshit and I hate it.

They’d have to. They can’t replace their writers and editors with AI if they admit it’s a terrible idea right now. NYTimes has been shit forever in general though.

That and bitcoin mining

[–] dragontamer@lemmy.world 6 points 2 days ago (1 children)

Bitcoin miners aren't buying nuclear reactors. https://www.technologyreview.com/2024/09/26/1104516/three-mile-island-microsoft/

AI is another order of magnitude more electrical usage than even the BTC bullshit.

lol holy shit I think the only company I would trust less with the responsibility of owning a nuclear reactor is boeing and I am not even sure on that one
