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.

Oh hang on, that number might of been counting fish/sea animals too? Idk, I still can't remember where I heard 'trillion' on this, but the infographic on Our World In Data could get that number up there with fish included as livestock.

Including fish as livestock is not particularly relevant for making a point on fresh water consumption though, so you were actually still right to call me out on this.

Yeah it’s easy to exaggerate numbers, I have to catch myself often. Fish could get us close I suppose (shrimp almost surely, but counting each one is problematic).

20 billion chickens is still an insane number anyway. And with so much of the US in drought it’s tough not to let it keep me up at night.
