The ocean has a vital part to play in the behaviour and long-term balance of the climate system. Oceans, which cover about two-thirds of the Earth’s surface, are crucial in the uptake and storage of both heat and carbon from the atmosphere. Global ocean currents, some of which operate on timescales of many hundreds of years , critically affect the long-term balance of heat transfer around the globe and directly influence climate in many areas of the world. As climate alters, we anticipate various changes to the oceans, both their composition and their circulation. Warmer waters, for example, can hold less carbon dioxide than colder, so as the climate warms the ability of the ocean to take up carbon dioxide from the atmosphere reduces. This is just one example among many.
