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.

Bypassing the question of whether sugars and oils are edible (?), field corn is perfectly edible for humans. Field corn isn't sweet corn, and doesn't taste good as a vegetable. But we can eat it the same way most people throughout history have eaten corn - as a staple crop, as a grain like wheat, as corn flour, cornmeal, grits, parched corn, hominy, maza, etc, etc. We just choose not to.

And calling opposition to ethanol "oil and gas propaganda" is ridiculous. Like the comment you responded to point it out, ethanol is sold mixed with gasoline. The industries are synergistic, not competitive. They have a common interest in promoting internal combustion engine vehicles and opposing EVs.
