Arctic and Antarctic regions also receive very little precipitation during the year, owing to the exceptionally cold dry air, however, both of them are generally classified as having polar climates.

According to polar climate researchers, as the extent of the Arctic summer ice pack recedes the route will become passable without the help of icebreakers for a greater period each summer.

Stocker said more analysis of White's ice core and a comparison with ice cores obtained elsewhere in Antarctica " are required to get a clearer picture " of the south polar climate change.

During the extremely frigid polar climate of the Last Glacial Maximum ( Late Weichselian Epoch ), 17, 000 to 24, 000 BP, small passive ice caps did form on the De Long Islands.

"These findings indicate that the differences between the caps are substantial ( rather than reflecting short-lived differences in frost cover ), and so support the idea of long-term asymmetry in the polar climates of Mars, " the report said.

In the last two decades, scores of researchers have come to the nearby town of Barrow, hoping to learn why the Arctic is warming so significantly and how the changing polar climate may affect the planet as a whole.

The Wind Chill Index ( WCI ) was developed in the early 1940s by P . A . Siple and C . F . Passel ( refined later by A . Court ) for use by scientists in polar climates.

( T-3 scientists watched the Skate punch through nearby sea ice in August 1958, a vivid demonstration that polar climate was a matter of military concern .)
