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.

You want to stop indigenous peoples burning wood for heat and cooking?

Yes actually, because turns out it does have a large impact on emissions https://www.sciencedirect.com/science/article/pii/S2590332221002967

The carbon footprint of the average person in Sub-Saharan Africa is nothing close to yours or mine. The idea that that article recommends eliminating wood-burning entirely is ... not born-out in its text.

What do you think the biomass in "Efficient Biomass Cooking" is? Its wood. The carbon footprint of the transportation of any other fuel to these people alone would more than offset any criteria by which wood-burning falls short, until we can electrify the entire world, and/or get everyone using solar ovens for cooking.
