Answer to Question 1

Changes that have been observed in the oceans due to global warming include increased ocean temperatures, changes in deep-water circulation, melting of polar ice, increase in ocean acidity, and rising sea level. These changes in the ocean will continue for centuries.

Answer to Question 2

Two main factors contribute to the global rise in sea level: (1 ) thermal expansion of ocean water as it warms and (2 ) an increase in the amount of water in the ocean from the melting of ice on land. Note that the melting of floating sea ice (such as in the Arctic Ocean) or floating ice shelves (such as those that fringe Antarctica) does not contribute to sea level rise because that ice/water is already in the ocean. More specifically, in order of their overall contribution to the observed global rise in sea level (Figure 16.31 ), the main contributors are: 1. The melting of the Antarctic and Greenland Ice Sheets; 2. The thermal expansion of ocean surface waters; 3. The melting of land glaciers and small ice caps; 4. The thermal expansion of deep-ocean waters

Did you know?

Over time, chronic hepatitis B virus and hepatitis C virus infections can progress to advanced liver disease, liver failure, and hepatocellular carcinoma. Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease. When combined with hepatitis B, hepatitis C now accounts for 75% percent of all cases of liver disease around the world. Liver failure caused by hepatitis C is now leading cause of liver transplants in the United States.

As many as 20% of Americans have been infected by the fungus known as Histoplasmosis. While most people are asymptomatic or only have slight symptoms, infection can progress to a rapid and potentially fatal superinfection.
