Climate - truthful information about climate, related activism and politics.

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.

How Bad Is A.I. for the Climate? Tech giants are building power-hungry data centers to run their artificial intelligence tools. The costs of that demand surge are becoming clearer. (messaging-custom-newsletters.nytimes.com)

Zero fossil fuels means zero in every industry.

Yeah, which is a solid goal! I don't know if you know this though, but most data centers run on renewables. They're way cheaper. Thats why there's so many data centers in regions with hydroelectric power stations.

This reads as pretty blatant oil industry propaganda trying to shift focus away from them and onto the current thing trump has made it trendy to hate. Down with big tech, those polluters with their... entirely electric infrastructure? If you want to get pissed about this, go after crypto miners. AI actually does something, and sometimes its even something overall positive for humanity! Crypto are just leeches.

The energy mix used by datacenters varies a LOT.

There are a bunch running on hydropower in the US pacific northwest, but also a ton which were co-located with coal-burning power plants in Virginia and Ohio.
