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.

Louisiana’s coast is sinking. Advocates say the governor is undermining efforts to save it. A new Republican governor is taking aim at the state’s coastal protection agency. (wapo.st)

I dunno so much about the rest of the state, but New Orleans has been sinking since it was founded.

Large parts of the state are uncompacted sediment. It does compress and settle as a result. There are a bunch of things you can do though:

  • Stop extracting and burning fossil fuels to slow sea level rise
  • Stop the oil and gas industry from cutting channels through marshes, which causes them to erode quickly
  • Divert sediment from the Mississippi to wetland restoration, raising land levels
  • Help people move when that's the best remaining option
