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.

TL;DR no

Certainly not in your home composter. You need heat >~145F for extended periods, your typical home composter only hits those temps for a short period of time because of how small they are. I've seen anecdotal home experiments on those really loud Sun Chip bags that are supposed to be compostable and they last for 1-2 years in home composters.

I thought this was meant to be the difference between biodegradable and compostable?

Biodegradable will degrade in an industrial composter, compostable will do so in the compost bin in your back garden.

Pay/reg walled from the article so didn't actually read it....
