The role of oceans in the climate system

Water has considerable thermal capacity, and the oceans absorb vast amounts of heat from the sun. At the same time, wind systems drive surface ocean currents. These ocean currents in turn affect the global climate by transporting considerable energy around the globe. At the ocean surface, the atmosphere and oceans exchange heat, moisture and gases, such as oxygen and carbon dioxide (CO2). The world’s oceans therefore play a key role in climate regulation, through the energy budget, carbon cycle and nutrient cycle. The oceans are also home to a rich and diverse flora and fauna. The oceans absorb and transport heat The oceans and the atmosphere receive heat from the sun. The areas around the equator receive the most, while the polar regions receive the least, which is why they are covered in ice. As a result of temperature differences, the oceans and the air are constantly moving. Heat from the sun sets winds and oceans in motion.
