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.

I'll note that this is article is concentrated on individual action, not on political action to change policy, which has a far bigger impact than individual action can.

This only works if you pretend the organic farm depletes soil carbon and emits NO2 at the same rate as the fertilizer farm, fugitive methane doesn't exist (anything with fossil gas in its upstream suplly chain has its emissions under-reported by a factor of about 3), and that the vast tracts of land poisoned and degraded by fracking are completely fine.

You also have to cherry pick small scale lifestyle blocks for your analysis and assume that the land previously degraded by industrial agriculture could be used further at the same yield.
