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.

Recycling was always a lie anyway. There's no true circular economy with plastic and a large portion of the recycled plastic is "recycled" into energy by burning it. It's always been a tool for manufacturing consent from the masses by making them feel like it's okay to use this much of a limited, non-renewable resource frivolously.

Yes, and many plastics are proprietary and can't be recycled. Truly, we need to just ditch plastic

Plastics recycling absolutely could work better, but you'd actually need some firm regulation around it: Only monomaterials, standardized types of plastic for per use case, labels that are either laser-etched or that fall off on their own, caps made of same material as the body, and no random surprises that ruin recycling.
