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.

In his judgement, Lord Ericht said a more detailed assessment of the fields' environmental impact was required, taking into account the effect on the climate of burning any fossil fuels extracted.

...

Shell's Jackdaw gas field in the North Sea was originally approved by the previous UK Conservative government, and the industry regulator, in summer 2022.

Permission for the Rosebank oil development, 80 miles west of Shetland in the North Atlantic, was granted in autumn 2023.

In a 57-page judgement, Lord Ericht wrote that there was a public interest in having the decision "remade on a lawful basis" because of the effects of climate change - which he said outweighed the interests of the developers.
