Environmentalist Dan Miller discusses images of arctic ice melting trends at the North Pole. He argues that light once reflected off the surface of the melting ice is now being absorbed by water, priming a feedback loop that will continuously acceler...ate the melting process. (03:03)

GreenlandData released this week by researchers who spent three months this spring measuring ice on the Arctic Ocean suggests that the North Pole could be largely open sea in summer within a decade—and ice free by 2029.

This five minute video discusses the impact of changing freshwater levels in the Arctic Ocean. Normally, a layer of colder freshwater resides above the warmer saltwater in the ocean, held in place by a circulation called the Beaufort Gyre and keeping... the surface ice from melting. However, periodically, the Gyre weakens, releasing the cold freshwater south, possibly interfering with the warm Gulf Stream in the Atlantic and keeping it from releasing heat into the atmosphere.
This could potentially affect the climate of the entire Northern Hemisphere, causing it to cool. A map of the currents and areas would be a plus when using this video. Interesting sidebar on how Polar Bears deal with scientific equipment.

During the summers of 2007 and 2008, year-round Arctic sea ice shrank to its lowest level since satellite records began 30 years ago. Some scientists now predict an ice-free Arctic summer by 2012. As snow and ice levels decline, sea-levels and weathe...r patterns are affected which in turn impact plant, animal, and human life.
