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.

My favorite is "cellulose insulation" used in attics. It's basically literally shredded magazines. So you have this fire-starting material chilling in your attic waiting to turn your roof into the Statue of Liberty's torch. Attics has soffit vents to let the fire motes in, and Bob's your uncle. Foam stuff isn't much better. Fire resistant material like fiberglass should be mandatory.

Cellulose insulation is usually treated to be fire resistant, meaning it will not spread the flame.

Unfortunately I don't think this is a mandatory treatment.

My attic is spayed on the underside of the roof, nothing below, maybe 10°F hotter in the summer. And that's ass cheap Habitat for Humanity home.
