British Antarctic scientists found the greatest temperature rise on record in the Antarctic, about half of a Celsius degree per decade, since 1947. (2.)

Models of the Arctic show that the cooling stratosphere has created ozone loss over the Polar Regions. (2.)

 NASA photos show the sea level is rising about 3 millimeters per year due to melting ice sheets. (2.)

 Many scientists believe that the continual temperature increase will completely melt the Arctic sea ice covering in the summer, and that the ice caps will only freeze in winter. (See the Topography Map of Polar Regions for more details.) (4.)

It has been estimated that one-fourth of the Antarctic sea ice has melted between 1950 and 1970 alone. This has been determined by whaling records, since whalers record the approximate location of the sea ice edge. (5.)

The average sea level throughout the world has risen about 10-25cm over the twentieth century. (6.)

Ice has decreased about 2.9% per decade, a combined figure for both the Arctic and the Antarctic regions. (7.)
