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 technically true, but rather misleading.

Meat animals eat plants. By not eating meat, you don't need to grow the plants to feed to the animals. Animals aren't perfectly efficient. To grow 100 calories of chicken breast takes way, way more than 100 calories of corn.

In fact, more land is used to grow feed crops than to grow crops directly eaten by people, even though most calories in our diet are from plants. And that's not not counting pasture and rangeland, which makes up an absolutely absurd amount of the US.

So yes: you'll increase the amount of runoff from chickpea and lentil fields, but you'll more than make up for that from much larger decreased runoff from soy and corn fields.
