The ocean plays a crucial role in Earth’s climate system by absorbing solar radiation and transporting heat from warmer to cooler areas. • Recent observations show that more heat is entering Earth’s atmosphere than is leaving it. However, the ocean only absorbs about 93% of this excess heat. • Ocean temperatures are measured by small robotic Argo pro?ling ?oats and Earth-orbiting satellites. • An important result from temperature data is that the ocean has warmed, but the spatial distribution of heat content change is strongly nonuniform. • As the ocean warms, it expands and the sea level rises. Sea-level rise is one of the best-measured indicators of global warming. Ocean warming also has negative effects on the uptake of CO2. Because the Earth is a sphere, there is a net heat gain near the Equator and a net heat loss at high latitudes. Atmospheric winds and oceanic currents must balance these heat surpluses and deficits by transporting heat from low to high latitudes. The ocean contributes about a quarter of the overall poleward heat transport accomplished by the atmosphere-ocean system; however, because the heat capacity and density of seawater are much greater than those of air (water can absorb more than 4000 times as much heat per unit volume as air), changes in oceanic heat content have profound and long-lasting effects on global and regional climate.m the atmosphere, and on the availability of oxygen for marine life.
