Answer 2

The oceans have a tremendous impact on the carbon cycle.

• Because the ocean retains fifty times more carbon than the atmosphere, it is crucial for carbon storage.
• Despite the quick two-way carbon exchange between the ocean's surface waters and the atmosphere, carbon can be preserved for millennia in the ocean's deepest strata.
• A variety of tiny organisms use bicarbonate to make shells.
• They die and sink to the ocean's depths, acting as carbon sinks.
• Unfortunately, rising acidity makes it more difficult for marine animals to produce carbonates.
• As a result, the carbon sink plummeted exactly when we needed it the most.
