2007: Impassable Northwest Passage Open For First Time In History (Uh?)

2010: Ship find shows Arctic Sea Ice conditions similar to 1853

This 1851 illustration shows the HMS Investigator on the north coast of Baring Island in the Arctic. Arctic archaeologists have found the ship that forged the final link in the Northwest Passage and was lost in the search for the Franklin expedition.

The international news media are hailing the archaeological find of a British naval ship the HMS Investigator on July 25 in an area far north (600 km) of the Arctic Circle that was previously unreachable due to sea ice. The HMS Investigator was abandoned in 1853, but not before sailing the last leg of the elusive Northwest Passage.

From AP/MSNBC: http://www.msnbc.msn.com/id/38459028/ns/technology_and_science-science/

"Captained by Robert McClure, the Investigator sailed in 1850. That year, McClure sailed the Investigator into the strait that now bears his name and realized that he was in the final leg of the Northwest Passage, the sea route across North America.

But before he could sail into the Beaufort Sea, the ship was blocked by pack ice and forced to winter-over in Prince of Wales Strait along the east coast of Banks Island."

From the Hockey Schtick: The ship had been sent on a rescue mission for 2 other ships mapping the Northwest Passage. Now, thanks to “climate change,” archaeologists working for Parks Canada were finally able to plot a small window of time this summer to allow passage to the ship’s location:

Parks Canada had been plotting the discovery of the three ships for more than a year, trying to figure out how to get the crews so far north. Once they arrived and got their bearings, the task seemed easier than originally thought. It took little more than 15 minutes to uncover the Investigator, officials told The Globe and Mail last week. “For a long time the area wasn’t open, but now it is because of climate change,” said Marc-André Bernier, chief of the Underwater Archaeology Service at Parks Canada.

Interesting that the ship was lost in 1853, right at the end of the Little Ice Age, and coincidentally just 3 years after the start of the HADCRU global temperature record, from which we are led to believe the earth has warmed about 0.7C. If we are seeing “unprecedented” global temperatures and changes in Arctic sea ice, how did the HMS Investigator get this far north at the end of the Little Ice Age?
