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.

Taking CO2 out of the air would be an absurdly expensive way to fight climate change (www.theverge.com)

If you want to return the climate to preindustrial levels you have to return the co2 level in the atmosphere to pre industrial levels. Your gonna need to figure out carbon capture at some point but seems like it’s second on the list after we stop generating new carbon.

There are enough people working this problem that we can realistically aim for both and capitalize on incremental improvements in each area along the way.

I agree. Too many cooks in the kitchen and all that. There's enough of us that we can diversify our efforts. A set of large teams working on eliminating carbon production, and a set of large teams working on carbon capture.

We don't really need to pick and choose. There's literally billions of people on earth.
