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.

The only way 2024 stays the hottest year on record is if civilization breaks down this year and no one keeps the record anymore.

Possibly not even then as we might already have caused a irreversible shift by melting the permafrost wich contained tons of Co2

We would have to go full nuclear winter for a few years.

No, I meant it will be the last year on record, cause no one is going to keep the weather stations running.

Ah... Well that makes sense but tbh, most weather stations are satellites and autonomous stations that run mostly without interactions, so it would take a few years for the recordings to stop completely.
