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.

Always a possibility. Now we know that won't work.

Edit: might have to prosecute grifters selling things they cannot deliver.

Lots of technologies were deemed not viable initially until they were improved enough that they became viable.

These guys just failed to develop the technology enough before starting to sell stuff they couldn't deliver and banked too much on government grants that are now drying up, and now they've starting to sack swathes of their staff because they're running out of cash.

Yes. Their small scale versions should have proven that it would work before expanding. I strongly suspect the small scale versions either did not work well, or were never built.
