The atlas clearly explains the role oceans play in battling climate change. In the Labrador Sea and Greenland Sea as well as in regions near the Antarctic coast, large quantities of surface water sink into the deep sea where carbon dioxide is stored for a long time. The lion’s share of the stored greenhouse gas since the start of the Industrial Revolution will take centuries to return to the surface of the ocean again. Part of it will remain fixed in the sediment of the sea floor. That is how the ocean significantly slows down climate change. However, the ability of the oceans to sequester carbon dioxide is not unlimited. For example, while carbon dioxide absorption in the Southern Ocean declined between 1980 and 2000, it has increased in the years since, according to the atlas. The ocean does more than absorb a considerable amount of the greenhouse gas. It also soaks up nearly all the additiol warmth resulting from the manmade greenhouse effect.
