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.

‘Risk’ analyses largely ignore the dangers of the climate crisis. Unless we wake up to them, they will soon outweigh all others

That would be great, but I doubt that. If US emissions stay stable that would be a 6.6% annual drop over a decade. If Carbonbriefs anslysis of Bidens climate policy is correct and US polizicans do not touch that at all, we are talking 10% annual drops. So far Chinas emissions have been growing most years. They might have peaked right now, but I foubt, they drop this quickly.
