Trends in Ocean Heat Penetration

Temperatures have increased both over land and water. Some of the heat from global warming gets stored in the world’s oceans causing higher water temperatures near the surface. This figure shows the trend in the heat content of the ocean between the surface and 700 meters deep. Warming of the oceans has many consequences, including sea level rise (warmer water expands), coral bleaching, loss of sea ice, and intensification of hurricanes.
