Arctic ice thins dramatically

Surface temperatures in the Arctic since 2005 have been higher than for any five-year period since record keeping began in 1880, according to a new report from the Arctic Monitoring and Assessment Program, an international group within the Arctic Council that monitors the Arctic environment and provides advice on Arctic environmental protection.

The rate of sea-ice decline has accelerated and the decline rate in the past 10 years has been higher than the Intergovernmental Panel on Climate Change predicted in 2007, the report says.

"Evidence from lake sediments, tree rings and ice cores indicates that Arctic summer temperatures have been higher in the past few decades than at any time in the past 2000 years," the report says. "Previously unseen weather patterns and ocean currents have been observed, including higher inflows of warm water entering the Arctic Ocean from the Pacific."

Temperatures in the Arctic permafrost have risen by up to 3.5 degrees in the past two to three decades, and the southern limit of the permafrost has been moving north, with the limit having retreated by 80 miles in the past 50 years in the Canadian province of Quebec, for example, the report says.

Most Arctic glaciers and ice caps have shrunk in the past 100 years, especially in Canada and southern Alaska. Climate models predict a 10 to 30 percent drop in the mass of mountain glaciers and ice caps by the end of the century, with the melting of the Greenland ice sheet expected to accelerate.

Overall loss of snow and ice cover will likely heighten the warming trend, mainly because the white snow and ice tend to reflect heat from sun, rather than allowing the heat to be absorbed by the darker land or ocean water. Scientists now think that Arctic sea-ice cover will all but disappear in the summer by mid-century.

Your proof of this is what? Come on, Cowbuns, show us some science backing your position. Or are you just a loudmouthed four flush?

Now I could post a hundred more articles where scientists state what they have observed in the Arctic in the past decade. Where is you proof that there observations are not correct?





Yes, please post all of them.
 
WASHINGTON, June 27, 2011 – With the number of geopolitical hotspots in the world today, the Arctic is not an area that comes quickly to mind for possible defense operations. But it is a place of great national security and strategic importance that the Defense Department and services are monitoring closely.

In a report sent to Congress earlier this month, DOD officials say the Arctic is a place they and the services are paying attention to because of rapid climate change there that likely will open the area to greater human inhabitation and possible threats to U.S. interests.

The polar icecap and harsh Arctic environment have long enhanced U.S. security by acting as a northern barrier to the United States, the report says. The melting of the icecap already is causing increased human activity, such as with oil and gas exploration and tourism, that could affect U.S. interests there and raise issues about maritime travel, it says.

Navy Adm. Gary Roughead, chief of naval operations, explained the level of U.S. interests in the Arctic during a June 16 Arctic seminar here. The region is “extraordinarily important for our Navy, for our military, and for our nation,” he said.

“There is a phenomenal event taking place on the planet today,” Roughead said, referring to the opening up of the Arctic Ocean from melting polar ice caps. “We haven’t had an ocean open on this planet since the end of the Ice Age. So, if this is not a significant change that requires new, and I would submit, brave thinking on the topic, I don’t know what other sort of physical event could produce that.”
