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.

Actually we are working hard to accelerate it.

That's the part that keeps getting missed. This all reminds of the yoyoing back and forth about whether coffee is healthy for you or not. Another damned science article on the issue. Great. Just what I needed. But the AMOC situation they always say is contingent upon action or inaction on global warming and what exactly am I supposed to think is happening to the systems? Hmm? Seems like everything is collapsing. So maybe I just might as well be fully prepared for the AMOC to straight up collapse. This groundhog day crap is getting really old. Same reason I always take a tote bag to the grocery store even if it's not always legally required in this county - sometimes they're out of bags, sometimes it's legally required; might as well be equipped with a bag.
