Geometry of the Oceans

The oceans influence climate over long and short time scales. The oceans and the atmosphere are tightly linked together to form the most dynamic component of the climate system. The oceans play a critical role in storing heat and carbon. The ocean's waters are being constantly moved by powerful currents which are mainly wind-driven. These currents influence the climate by transporting heat. Currents involved in 'deep-water formation' are particularly important for climate. Apparently a small change in just one aspect of the ocean's behaviour can produce major climate variations over large areas of the Earth.
