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'm picturing a field of potatoes, beans and hemp laid out in optimized patterns and never 100% harvested. Throw in patches of natives and flowers and some shading solar panels you'd be really cookin... If feasable to totally no till and if it worked, after season, bring in some cows to clear the dead beans and after a few days, chickens to feast upon the poo-munchin invertabrates. Do soil maintenance if necessary... Add fruit trees for the lullz. Harvesting would have to be really clever... I bet after a decade or so, upkeep costs woild optimize.

Oh hush; it's my naive fantasy and I can do what I want.
