This idea was already publicized and dispelled when I was in university studying Climatology, 15 years ago.
It fucks up the oceans' pH balance, likely kills off more marine life than it feeds, and >90% of the CO2 is re-emitted within a few years anyway, cause there's no way an ecosystem will just let nutritious unoxidized carbon go to waste on the sea floor.

wouldn't this make the ocean more acidic which is already a problem. I thought one of the problems with global warming was the ocean absorbing more co2 which makes it more acidic which destroys a lot of sea life.

It's not being dissolved into the water, which would raise the acidity, but instead being sequestered into particles which sink to the bottom.

I won't say there is definitely no unintended consequence, but I don't think that one is likely to happen.

Ok. I reread it and I can see that. first read it sounded like it was just getting dropped and processed by organisms deeper in the ocean. If it gets it out of reach of organisms that process it back to co2 then that would be good.

Climate - truthful information about climate, related activism and politics.

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.
