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.

Large-scale tree planting can remove some CO2 from the atmosphere, but nowhere near as much as humans add by extracting and burning fossil fuels. See https://skepticalscience.com/1-trillion-trees-impact.html for a detailed assessment of what this looks like.

The IPCC has a chart showing what actions need to be taken over the next few years. Afforestation is one piece of many things, all of which we need to do.

If conservatives (or dems) were smart they'd lean hard into something like the CCC https://en.wikipedia.org/wiki/Civilian_Conservation_Corps?wprov=sfla1

Teach young people life skills, lift a whole generation out of poverty, plant and manage forests, fix up our infrastructure... So much could be done. A modern, environment-focused CCC would be revolutionary, and I would bet whoever runs with some form of that idea first sweeps the following elections.

It was proposed as part of the Green New Deal but hasn't been able to meaningful funding through the Senate. Too many Republicans working with a handful of bought-off Democrats

I didn't know that! Neat. I hope it stays a part of the conversation.
