In laboratory experiments, they observed that diatoms under [...] deep ocean. Thus, the CO 2 is removed from the global carbon cycle for a couple of thousand years.

IPCC Climate Change Ocean acidification Anthropogenic climate change is altering the living conditions in the ocean more dramatically than in the past 50 to 300 million years. The oceans are becoming warmer [...] which chemically react with constituents of seawater, making the oceans more acidic. But that’s not all: for various reasons, warming oceans store less oxygen. In other words, they gradually lose their lifeblood [...] in the seas simultaneously reduces the number of safe havens remaining to them. Increasing ocean acidification puts organisms under additional pressure. Further, these three climate impacts are mutually
