Arctic sea ice set to reach its lowest extent ever recorded

Ice volume in the Arctic has declined dramatically over the past decade.  Unprecedented rate of Arctic sea ice melt is set to reach its lowest extent ever recorded by the end of this week.Current melt rate of more than 100,000 square kilometers per day is expected

Rapid ice melt opens Arctic's Northwest Passage

Ice retreated rapidly in the Parry Channel between mid-July and early August 2012. Parry Channel is a part of elusive Northwest Passage. The loss of Arctic sea ice is predicted to open up the Northwest Passage, shortening shipping routes and facilitating the exchange

Great Arctic Cyclone of 2012 - Rare and unusually strong storm formed over Arctic

An unusually strong storm formed off the coast of Alaska on Aug. 5, then moved over the central Arctic. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite took the images that make up the mosaic during various passes over the North Pole

Big picture Flooding in 012

Satellite images show flooding in Kangerlussuaq, Greenland

Recent satellite images show flooding in Kangerlussuaq, a key air transportation hub on Greenland. Located in southwestern Greenland roughly 125 kilometers (75 miles) from the coast, Kangerlussuaq, or Kanger, hosts one of the island’s busiest commercial airports.

Tropical plankton invades Arctic waters

Scientists have identified tropical and subtropical species of marine protozoa living in the Arctic Ocean for the first time. It looks like they traveled thousands of miles on Atlantic currents and ended up above Norway with an unusual-but naturally cyclic-pulse of

97% of the Greenland's ice sheet surface melted in mid-July

Greenland's surface ice cover melted over a larger area than at any time in more than 30 years of satellite observations in period of merely few days this month. Nearly the entire ice cover of Greenland, from its thin, low-lying coastal edges to its two-mile-thick

Massive iceberg breaks off from Petermann Glacier on Greenland

Another spectacular event on Greenland this year is second big calving of Petermann Glacier, following retreats of the Jakobshavn Glacier and lowest reflectivity of the Greenland ice sheet on record. This calving was expected to happen, as the rift in the glacier has

Are we facing an end of Antarctic as we know it?

Regional warming, over-fishing, pollution, invasive species creeping into the area, ocean acidification and loss of sea ice around South Pole region are the most immediate threats for waters around Antarctic. And all those threats are linked to global levels of carbon

Unusual sea ice retreat in the Beaufort Sea

Sea ice retreat in June is typical, as the summer solstice approaches in the Northern Hemisphere with long hours of sunlight to warm the Arctic and melt snow and sea ice. However, the first half of June 2012 brought unusually rapid ice loss.One area of rapid ice

Researchers found evidence of warm periods in Arctic

Analytical results from the longest sediment core that has ever been drilled in the terrestrial areas of the Arctic have shown temperatures that were previously considered impossible for the Arctic Circle. In addition, a notable correlation of the warm periods in the

Unexpected discovery - Arctic Ocean is richer in microscopic plants than any other ocean on Earth

Scientists have made a biological discovery in Arctic Ocean waters as dramatic and unexpected as finding a rainforest in the middle of a desert. A NASA-sponsored expedition punched through three-foot thick sea ice to find waters richer in microscopic marine plants,

Shrubs in the Arctic tundra transformed into trees

Shrubs in the Arctic tundra have transformed themselves into trees as a result of the warming Arctic climate in the last few decades. The speed and magnitude of change is far greater than scientists had ever anticipated. If this continues and is replicated across the

Scientists say shockwaves from melting icecaps are triggering earthquakes

High up inside the Arctic circle the melting of Greenland's ice sheet has accelerated so dramatically that it is triggering earthquakes.Scientists monitoring the glaciers have revealed that movements of gigantic pieces of ice are creating shockwaves that register up
