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.

1.5C is dead. The climate fight isn’t. | Trump’s re-election is “the final nail in the coffin” for the Paris Agreement's North Star goal, nine experts told HEATED. But we can still limit the damage. (heated.world)

IPCC declared 1.5C wasn't feasible a few years ago. I don't recall the year, but it's the same report when they said that the limit would be broken, but we'd find a way to pull it back down eventually with future tech. Or as some call it, "magic".

"BuT AI aNd QuAnTuM cOmPuTeRs WiLl SoLvE cLiMaTe ChAnGe." as if AI is going to magically convince governments profitting trillions of dollars to stop the oil industries.
