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.

One of the neatest things I've learned about on Technology Connections was an induction cooktop that used 120V electricity. It had a bank of batteries in it that would provide power for cooking without overloading the mains, and you could plug appliances into it in the event of a power failure and still be able to cook.

If you had appliances storing energy like that you could level out demand curves. And you can also store energy with heat. If we had temperature regulator valves on our water heaters, we could get them to 160-170 degrees when energy is cheap and let them coast down to 120. Heating water is one of the major energy expenditures for a home, so if we could get that to be 100% renewable would be a huge advance.
