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.

about half of the land attributed to livestock is grazing/pasture land. of the crop land, almost all of that is also producing plants for some other use. as much corn, for instance, becomes ethanol as is fed to livestock. and livestock are also fed crop seconds or waste from other crops like cottonseed.

Thr vast majority of animals are factory farmed, so the idea that pasture land is feeding any noticable amount of animals is just wrong.

I would love a source for anything you're saying.

The fact that corn is also grown for ethanol in no way changes that more corn is grown for them to eat does it? Like the corn fed to animals cant be used for ethanol. Also what use does feeding them oats accomplish?

All beef cattle graze for about their first year. The only spend the last 4 months or so in a concentrated feeding operation.
