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.

a third of cropland is literally dedicated to growing livestock feed

that's not what your source says. and all of agriculture is about 20% of our emissions, but i'd be fine if it were 100%: we need to eat.

Twenty-six percent of the Planet's ice-free land is used for livestock grazing and 33 percent of croplands are used for livestock feed production.

Dude, it's one of the first things written on the first page. Come on now, this is embarassing.

33 percent of croplands are used for livestock feed production.

but not exclusively for livestock feed production. it's not "dedicated".

This is what this user posted and embarrassingly deleted before writing the comment above:

grazing lands aren't croplands

If you can't even be bothered to read a full quote that was handed to you, you aren't discussing in good faith. You can go ahead and fuck off with your hand wavy non-scientific bullshit. Learn to read a source and provide a proper rebuttal with evidence instead of spamming nonsense.

Edit: Oh look I broke the spambot lol

this is clearly a bad-faith attempt to avoid the fact that im right: in feeding animals the unwanted parts of our crops, animals actually help conserve water.

calling me a spambot doesn't change whether i'm right, or you're literate.
