As a main heat store for the world it has shown rapid and accelerating change in sea temperatures over the last few decades and has buffered many of the changes seen on land attributed to climate warming. It is the main store of carbon dioxide (CO 2), each year taking in about 2 petagram (2 x 10 15 g) from the atmosphere and exporting carbon via physical and biological processes to the deep ocean reservoir. ...
