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.

this is warmed-over poore-nemecek 2018. that's the primary basis for the claims about the climate, but the methodology of that study is fucked, and it's a disservice to actual climate science to keep touting this meta"study" that misuses its source material and myopically focuses on distilling data instead of understanding the complexity of our agricultural systems. the textile industry's water use, land use, and emissions, i guarantee, are being counted in poore-nemecek as emissions from beef. i didn't pull out the data from the separate reference to water use, but i will eat my hat if that doesn't, as well.

eating less beef has not been effective at stopping the growth of the beef industry for all the people who have done so. we need a real solution, and trying to influence individual consumer choice isn't working.

edit: down voting doesn't change the truth
