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 the stupid shit we get for letting Iowa always be first in the nominating contests.

Not all candidates. Just all democrat and republican candidates.

So all actual candidates.

Self fulfilling prophecies

anything that isn't a solution is violence against the people who can't afford to survive 3 degrees of warming and we need to defend ourselves right now.

Economists believe is something called externalities. Its very important and it corrects the market. If something is good for the world then you government needs to make it cheaper by subsiding it. If it's bad then their should be a tax on it. Economist gernally strongly support this but the public seem to be against this.

This here is giving money to farmers. It's basically the opposite of externalities. It's really stupid.

Compare this to gasoline. Same engine, right?

For cars older than a decade, is it or is it not marginally better than inefficient and toxic gasoline?

There's a fair bit of evidence that the ethanol is worse:

the carbon intensity of corn ethanol produced under the RFS is no less than gasoline and likely at least 24% higher
