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.

This is the UK, land of the GCHQ (same as the NSA, but worse, and when the Snowden revelations brought up what they were doing, it was simply made legal, unlike in the US), the most video surveillance cameras per person in the World, were they've been using techniques such as kettling of demonstrations for years and were the police were early adopters of AI face recognition cameras.

That place is hugelly authoritarian, they're just posh about it and their use of violence against normal people tends to hide behind "rules and regulations" unlike cruder nations were the cops just shoot them.
