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.

To be clear: there's a night-and-day difference between Biden and Trump, with the former having actually taking significant action, and being likely to take more if reelected. Trump will look to maximize both extraction and consumption of fossil fuels in a way that Biden simply didn't and won't.

That captures the insanity of the political positions very well.

Not insane. Age-related cognitive issues notwithstanding, both candidates know what they're doing. It's impossible to make someone understand something when their livelihood depends on their not understanding it. In this analogy, both guys are paid by the sharks who made the hole in the first place to pretend the patch kit doesn't exist.
