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.

Electrolysis powered by PV solar of CO2 into acetate can increase plant yields by 4x compared to just sunlight. Technology and bioengineering of plants can improve it even more.

This can make cheap buildings powered by PV more cost effective than open land farming. No pesticides or fungicides, and less fertilizer use.

An important role that livestock provides is that of a food battery. Climate vulnerable crop yields allow for culling livestock when plant yield is more scarce. Indoor ag provides climate and seasonal resilient food output.
