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.

Yes, the tone is a bit hyperventilatory and the author is not especially authoritative (on this subject), but the argument is really quite convincing.

The climate movement has been so focused on reducing emissions for so long, it’s lost all sight of the fact that there are other ways to bring carbon dioxide concentrations under control. [...]

Marine Carbon Dioxide Removal was always something we were going to have to do. In the new Trump era of not even pretending to try to curb emissions, the urgency to act is all the greater.

And, right now, seaweed might be our best hope.

Alls I’m saying folks, I’m not done until I’m six feet deep in the ground.
