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)

Collectively we should be able to care about multiple things at once and also prioritze between them.

Even if data centers use mostly renewables, its not like those are actually so abundant that they would go unused. Its important to not just switch power generation but to actually also reduce power consumption, especially when its such low hanging fruits as AI.
