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.

Any chance of limiting global warming to 1.5˚C rests on Joe Biden being elected to a second term. Voters need an accurate accounting of Biden’s climate record ahead of the November 2024 election.

If you're in the US and want to get involved, you can volunteer or give to the Biden Victory Fund

You do it by framing the debate around meaningful policy changes, and immediately delivering on those changes at every opportunity to do so. Progressive policies will meaningfully improve people’s lives in almost every way. Force those centrist voters to think. Clearly paint a picture of the vast wealth inequality that exists between the elite and normal Americans. Force them to ask themselves why other candidates don’t want them to have better pay, more time with their families, free access to the best medical care, and free access to higher learning to improve themselves and learn new skills. These things are the “bootstraps” repugs love to harp on about, and progressives must lead the charge in enabling our people to take hold of them.
