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.

When I was a kid I read a wonderful book about how a lady bought a vacuum cleaner to save time cleaning her floors. Then other people saw how great it was and bought vacuum cleaners. Eventually they were so popular that a vacuum cleaner factory was built in her town. Of course they needed more electricity to run all the vacuum cleaners and the factory, so a new power plant was also built in the city. The power plant, and the vacuum cleaner factory pumped soot into the air, which dirtied all the walls and floors across the town. Eventually with more work than she used to expend sweeping, she could get her floor almost as clean as before she bought the vacuum cleaner. I have no idea what that book was called, but the message has always stuck with me, and it seems very relevant to the topic of this post.
