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 between 1973 and 2007 at a rate of about 10% per decade.

All BUT ONE factor may be responsible for the gradual decline in sea ice. That is

• global warming.

• rising sea level.

• increased atmospheric carbon dioxide.
