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.

It seems that someone noticed that absorbing CO2 leads to ocean acidity rising (the carbonate ion, CO3, is a negatively charged ion with a nominal charge of -2).

Neutralizing CO3 by providing it something permanent to bind with - for example by forming NaHCO3 - will likely have the desired effect (nobody goes testing with a ship without first testing in a lab)...

...but the scale of the task makes me doubt if this is a feasible / reasonable approach. All that sodium to make soda would have to be produced somehow, without emitting almost any CO2. This, I have doubts about feasibility.
