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.

Two former staffers of the US agency responsible for advancing the technology argue that the profit-driven industry’s focus on cleaning up corporate emissions will come at the expense of helping to pull the planet back from dangerous levels of warming.

The most obvious lever for that is a CO2 emissions price on the same level as the price for its removal. CRT are insanely expensive so an emissions price based on that is nicely arguable as long as they promote CRT and the high emissions price would accelerate the transition immensely.

Tax every single thing based on the CO2 equivalent emissions over its entire lifecycle and use those funds for an equal payout to every citizen to offset the social inequality of such a tax.
