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.

Black and white cartoon. Left panel: a group blocks a road with a banner reading "No new oil | so there's a liveable planet for our children." Right panel: A boardroom, with members of the board raising their hands. In front of them is a chart showing planned oil extraction going well above a dashed line marked "Level beyond which there will be no livable plant for our children.

What happened to circuit board assembly volume after people stopped buying blackberry phones? Cell phone ownership? Smart phone ownership?

The same plants that made rim components are making components for the phones we have now and production has increased. The mines that extracted coltan, copper, gold, oil and many more raw materials used in the manufacture of rim devices are still operating and total global production has increased.

Removing one product of a complex supply chain will not cause that chain to go slack. The market will find a place to sell its output and if there isn’t one it will manufacture it. If there isn’t demand it will manufacture that too.

We cannot stop emission at the point of consumption.

I didn’t say anything about a militant movement at the point of production (although I think it will be required when we tell the people making billions that the factory has to shut down or shift to something less profitable). What I said was that boycotts don’t work unless paired with a militant movement, which is borne out by the few examples of boycotts involved in successful struggles (Montgomery, arguably bds, etc.).
