Refer to the diagram showing the decline in Arctic sea ice cover from 1973 to 2007. Large-scale measurements of sea-ice became possible with the development of satellite technology. Scientists have determined that the September Arctic Sea ice cover has decreased by about 10% per decade. All BUT ONE of the following factors may be responsible for the gradual decline in sea ice. Which factor is NOT responsible?

• global warming

• rising sea level

• increased atmospheric carbon dioxide

• increased average annual temperature
