Changing Planet: Ocean Temperatures

Observations document that the Earth's ocean is warming. As the ocean warms, it will also expand in volume, causing sea level to rise. This rise is in addition to the sea level rise that results from water added from melting ice and snow that comes from land-based sources. Today, there are large human populations living in coastal areas worldwide that will be affected by rising sea level.
