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.

Because we're being wise enough to question if this might have unintended consequences. For example, it might just shift the problem elsewhere and cause more severe draughts for someone else. Just a hypothetical to point out why people might not be immediately onboard with this.

Tho, fun fact, California has been doing this kind of stuff since at least the 60's. It's called cloud seeding and we've had numerous programs running. They just never got much attention. But technically, the chem trails conspiracy is based in a bit of truth. It's just not every airplane, but it's happening. A quick Google search will give you tons of government pages about it. It's not a secret.
