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.

“Ultimately, we want to use less fuel, not more, and so we should be looking at increasing vehicle efficiency more,” he said. “We should be looking at public transportation options.”

The article doesn't get into it much, but an acre of solar panels provides a lot more vehicle-miles than an acre of corn turned into ethanol.

I can't comment on the vehicle-miles per acre but solar panels in Minnesota should produce plenty of energy from March-April until September-October. Many Germans have solar panels and Minnesota is south of Germany which means they have even more sun.
