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.

China, the world's biggest emitter of carbon dioxide, produces 12.7 billion metric tons of emissions annually. That dwarfs U.S. emissions, currently about 5.9 billion tons annually

What about China? Are you purposely ignoring China because you’re a tankie? I’m not saying the US is innocent but it seems like you’re not being entirely factual here about the biggest polluters.

Also, I wasn’t able to find the info all in one place but the figures I’m seeing about military carbon footprints are as follows between the two nations:

US: 59,000,000,000 tons

China: 95,000,000,000 tons

So, I obviously agree that the US has a carbon footprint problem but you seem to be putting most of the blame on the second largest offender and ignroing the first. A suspicious thing to do for anyone other than a tankie, looking to distort the truth.

Two obvious things: China has 2-3 x the people. Maybe adjust to a per person basis? Or a per GDP ratio if you are so inclined. Also, most of the stuff for sale comes from China - so we just moved our emissions there. This is super hard to adjust for, but should be considered a bit.

On your second point, I’m mainly referring to military carbon footprints.

I’ll do the GDP scaling when I’m not out and about unless you want to do it first.
