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.

We are dying here, literally, and this is a major victory, but it's damned near nada and we're still dying here.

We're not dying, though. We're still alive. We might be heading towards climate disaster, but we aren't there yet, and the future isn't a forgone conclusion; don't give into the idea that we're already dead and just don't know it. If Montana ends up being the one safe haven for climate study (and it probably won't be alone), I'll take that over whatever cockamamie "plans" the next admin has.

As long as science can keep happening in relative safety, we have hope of progress.
