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.

Anyone who understands the concentration of CO2 in the air knows that these things are nothing but a PR stunt. You're not going to pull enough out of the air to have any meaningful contribution; there's just not a lot there to pull out. For all the harm it's causing, CO2 makes up a tiny part of air composition, only about 0.04%.

These things are built for idiots who think the solution is as simple as "just run the air through a filter" and don't grasp how much air there actually is, and how little there is to pull out.

That's what the article is about. It also goes into biomass energy land use and the unknown effectiveness of grinding up rocks + laying them on farmland
