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.

Down cycling is good. But the best is to just not produce plastics where wood, metal, and glass alternatives exist or actually pre-date their plastic counterparts.

Why do produce containers have to be made of plastic when they can be made from compostable cardboard or wood scrap?

Meat used to come wrapped in paper instead of plastic foam. It still could be. Milk used to come in glass or metal.

Most toy or parcel packaging could come in tissue paper or cardboard.

The only thing that might actually need plastics are medical devices like catheters or other things that cannot be fully sterilized by an autoclave (or might become irradiated).
