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.

Thank you, Comrade Trump | The Strait of Epstein crisis is going to do more to accelerate permanent, unidirectional migration away from fossil fuels to cleantech than decades of environmental activism (pluralistic.net)

As strange as it seems given the whole, you know, this, the United States is only a small part of the world.

Little Donald ordering closed coal plants to reopen like a Captain Planet villain is only going to impact a relatively small number of power plants - and those coal plants are going to close back down as soon as they're legally allowed to, for the same reason they closed in the first place, because they don't make economic sense anymore.

Meanwhile, the people buying solar because they can't trust oil and gas supplies, and the governments investing in renewables because they don't want to be held hostage the next time the United States gets a bug up its ass about Iran, will still have those solar and renewables long after Little Donald has retired to his private massage parlor in Mar-A-Lago.
