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.

emissions down in last 10 months of 2024. Very likely that trailing 12 months are down too (not covered in article, but something they will pick up)

+1, but with the addendum that the next few years might not look good for the US.

thats true, i’ve also read

and with his recent wacky economic policies likely to cause a recession which will result in less demand which will also reduce co2 is just one of those great ironies

It’s already hit oil companies hard, again massively ironic, heh. Especially if other countries tariff US oil… which I haven’t heard, but strategically is not a bad idea.

If the tariffs get high enough, it will just mean more American oil will be used domestically.
