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.

Is the Gulf of Mexico the ‘single best opportunity’ to store climate-warming gas — or an existential threat to wildlife and people?

In the worst-case scenario, underwater carbon sequestration wells could fail and release the stored carbon, killing off the plants, fish and even the people in boats in the waters above. Storing carbon also has potential global implications, if, as opponents claim, carbon capture and sequestration will allow the fossil fuel industry to maintain the status quo as one of the world’s top emitters of greenhouse gasses.

Since this is almost certainly going to be what fossil fuel and other ultracapitalists want, I would expect lots of corner-cutting that leads to failed wells, followed by some toothless wrist-slapping by whatever remains of the regulatory bodies tasked with oversight of these companies.
