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.

Why aren’t climate-damaging subsidies on the chopping block? (livestock and cars) (slrpnk.net)

Asking the gov to proactively shrink or limit animal products is a non-starter because there are just too many (voting) consumers who would be outraged. It would be political suicide. Same for cars. Forcing car owners out of cars would be political suicide as well.

But what I find baffling is there seems to be no chatter about the fact that the US gov gives (millions?) in subsidies to livestock farmers. And Europe gives tax breaks for “commercial” cars (mischaracterized personal cars). If the gov were to end the subsidies, there could be no reasonable complaint that the gov is interfering. Because in fact the gov would be ending their intervention.

Okay but I was just talking about subsidies. I don’t think personal cars are being subsidized in the US, are they? I thought you had to be a truly commercial driver for the most part (taxi or 16-wheeler) to get a tax write-off.
