Why are the oceans important?

Ocean currents transport large amounts of heat and water around the world and constantly interact with the atmosphere, which enables the ocean to act as a heat sink to delay the full effects of climate change. Carbon is continuously cycled between reservoirs in the ocean, on land and in the atmosphe ...
