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.

As usual when it comes to climate impact, the US will be fine. Three out of every four calories of corn is used to make ethanol or feed animals, both of which are ridiculously inefficient uses. Hell, corn syrup is in everything because the US grows so much more corn than it needs that we practically give away the corn syrup.

Soybeans are even less efficient - less than 3% of the American soybean crop is actually eaten by human beings, despite soybeans being a complete vegetable protein and one of the healthiest foods out there.

In other words, the United States could lose 9/10ths of the land growing corn and soybeans and still feed itself with plenty to spare.

All that land is only under cultivation at all because the United States can't stand the idea of giving up one foot of the land it stole in the name of manifest destiny. Because if we weren't using land for corn and beans in the Midwest or grazing cattle in the Great Plains, people might start asking why not give it back to the indigenous peoples we stole it from.

So yeah, America will be fine.

It's the rest of the world that's going to suffer for America's climate crimes.

I guess this will raise the prices for the non-key crops also
