The ocean plays an important role in the global carbon cycle by absorbing about one-quarter of the carbon emitted by human activities every year. A study published recently in Nature Geoscience and co-authored by a University of Hawaiʻi at Mānoa oceanographer revealed about 6% of the total uptake of carbon dioxide (CO2) by the ocean is due to rainfall.
