Bart,

There's a type of natural ice pack opening called a polynya that can be caused by warm water upwelling. I don't see how the existence of temporary polynyas is a valid argument against the theory of agw...

Polynya
en.wikipedia.org

A polynya /p?'l?nj?/ is an area of open water surrounded by sea ice.[1] It is now used as geographical term for an area of unfrozen sea within the ice pack. It is a loanword from Russian: ??????? (polynya) Russian pronunciation: [p?l?'n?ja], which refers to a natural ice hole, and was adopted in the 19th century by polar explorers to describe navigable portions of the sea.[2][3] In past decades, for example, some polynyas, such as the Weddell Polynya, have lasted over multiple winters (1974–1976).[4]

When submarines of the U.S. Navy made expeditions to the North Pole in the 1950s and 60s, there was a significant concern about surfacing through the thick pack ice of the Arctic Ocean. In 1962, both the USS Skate and USS Seadragon surfaced within the same, large polynya near the North Pole, for the first polar rendezvous of the U.S. Atlantic Fleet and the U.S. Pacific Fleet.[7]
