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.

40% of global ship traffic is simply moving fossil fuels around! Renewables make much of this traffic obsolete (slrpnk.net)

Renewables... And also reduction. People need to grow up and realize that driving a vanity tank for half a mile to get a gallon of milk is fundamentally unsustainable. Humanity and the planet can no longer afford to support this level of gross privilege, regardless of the "fuel" used.

Electric busses, and trains need to be part of the solution.

And walking. Cities shouldn't be as spread out as they currently are, especially in the US.
