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.

The world’s biggest plant to pull carbon from the sky just opened | Experts say we’ll need carbon capture to offset stubborn emissions that can’t easily be cut with existing green technology. (wapo.st)

the plant is designed to remove 36,000 metric tons of carbon each year, the equivalent of taking 8,600 cars off the road.

In short, for removal like this to make a meaningful difference, and not just function as a PR exercise, we'll need to cut emissions to almost zero.

If it gets used in any meaningful way, it'll be for cleaning up what we can after we stop using fossil fuels
