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.

“Let’s take all that yucky methane released by cows and make it fuel!”

  • how’s that help?
    “It keeps the carbon from entering the atmosphere.”
  • okay genius. What uses the fuel?
    “Engines I suppose”.
  • and the engine combusts it and creates…?
    “Exhaust?”
  • and that exhaust is made of…?
    “CO2 and NOx and SOx.”
  • and is released to…?
    “The atmosphere.”
  • So how does that help?
    “I have a new fuel revenue stream.”

Methane is roughy 1000x as potent at global warming as CO2.

You may not like cattle farming, but take the win.

Gonna need a source on your 1000x. I can find 27.9x the potential, per unit mass. I think my point still stands: they're taking a problem and merely converting it into a different form of the problem, and calling it a solution.

Reduce, reuse, recycle.

I think you need to compare the greenhouse effect from methane as compared to that CO2, NOx and SOx released by burning off the methane. There is a reasone the EPA requires waste water treatment plants to flare off methane rather than freely releasing it.
