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.

“Trump wants fossil fuels and the United States is indeed a powerful petro-state,” Bremmer said. “But letting China become the world’s sole powerful electro-state is the opposite of making America great again … at least if you care about the future.”

One thing i've come to understand is that america does not at all seem to care even the slightest bit about having a future. Which, in my opinion, is super weird because it says in the bible (that the christians revere so much) that "when your messiah comes [for the second time] and you happen to have a sapling in your hand, plant the sapling first, then go see the messiah". Which means, especially if you consider it to be the "end times", that doesn't mean you should just not care about what happens after. You should still plant the tree, even if it takes 20 years for it to grow up and produce meaningful amounts of fruit.

But i guess something about wanting to have a future is "communist" or something.
