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.

Self reply. I wonder what the climate impact of my compost pile is. Should I add seaweed? I live a long way from the sea, is the pile worse than a 400km round trip (presuming the right weed grows in the nearest bit of sea).

I hope fixing electricity, residential, commercial, transport, and industry is enough. The world could handle the carbon load of the same sort of biomass as we have now before we started burning all the oil

Usually compost is made from stuff that would otherwise be waste. The stuff in your compost would rot and off-gas anyways. I think intentionally composting actually results in less emissions than what would happen naturally or in a landfill. I wouldn't buy stuff just to compost it (I'd just buy compost, which, in my area, is usually made from yard waste collected by local municipalities). If you need a lot of compost you can usually intercept quite a bit of material from the normal waste streams for free. I.e. you can usually get arborists to dump tons of woodchips in your yard, talk to coffee shops to see if they'll give you their spent coffee grounds, etc.
