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.

yeah yeah yeah, we'll try to act surprised even though we're all slaves to systems that prop up billionaires who do nothing but bad for the planet and species because who gives a fuck about all of us working ants and roaches who would crawl over them if given the chance.

no one does anything, we all just met h toward the end so fuck it.

People have actually done a lot; we've shifted from a path where were likely to see 4°C or more by 2100 to one where we're likely to see something like 3°C by then.

It's not yet enough, but it's a lot more than nothing.
