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.

Pulling CO2 out of the air won’t stop climate change…unless it is stored for at least 1,000 years. Researchers pinpoint an unexpected threat to climate action: ambiguous carbon accounting (www.anthropocenemagazine.org)

Better to make stuff with it. Like diamonds, graphene, or carbon nanotubes.

How about wood?

It grows on trees, and if we bury it under anerobic conditions it won't rot and release the stored carbon. No need for sealants or preservatives, the wooden piles that the city of Venice was built on are still intact after hundreds of years buried in mud.

Bonus, we can drive wooden piles vertically into the earth to stabilize it. That will help us address the landslides that have become more common due to the changing climate.
