Climate - truthful information about climate, related activism and politics.

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.

Do you have a solution?

Short of mining the moon to make orbital mirrors out of lunar tin foil, foucus on rapid and complete decarbonisation while accepting that there were consequences to largely ignoreing the problem for the last sixty years.

This isrl relatable to so many people wait until the absolute last second before starting to do anything. Procrastination ftw.

Solution is a maybe an overstatement, but

  • destroy the methane. That's energetically favorable, so it can be done more easily. Makes some CO2 but it's 50x less bad that way.
  • get the carbon back out and stick it into the ground. We'll be on our way when the Mauna Loa CO2 curve bends and goes down for a year or two. That's energetically expensive, but we'll figure out a way (hopefully) to do it wherever we have solar overproduction.

Trees are nice, but it's nowhere near enough to do that.

Trees are a way to get the carbon out of the air and put it back in the ground. There is probably a plant that would be better suited for the purpose of sequestering carbon though. I don't know what it is.

Charm Industrial likes Switchgrass I think. To make oil to pump back under.
