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.

As much as I’m aware of the existential threat of the climate crisis, I dislike the superlatives António Guterres uses about it. This time "we opened gates to hell", last time "the era of global boiling had arrived". Also we "are on an highway to hell with the foot on the accelerator". Except hellish lava is not flowing in the streets and the oceans aren’t actually boiling. I wish he’d just go with the facts. The fundamental transformation of our planet. Its increasing hostility towards all life. The cataclysmic weather events. The ecological collapse. The mass extinction. The deaths. This hits harder than the allegories and leaves no place for dismissal or ridicule.
