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

New study maps glacier mass change in the Himalayas

Glacial  reservoirs are among largest  freshwater deposits on Earth. About 1% of global sea level rise is caused by melting - that's about 3-4% of the total  global glaciers and ice caps. However, researchers don't have enough data considering regional behaviour

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.

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

Footage of Upsala Glacier capsizing

A tourist traveling on a catamaran in Argentina caught rare footage of the Upsala glacier flipping over.The huge iceberg lost a part of itself and then flipped over with a huge roar according to tourist who witnessed the event from catamaran and recorded it on

Scientists have found more than 150,000 sites in the Arctic where methane is seeping into the atmosphere

According to a report published in the journal Nature Geoscience, scientists have found more than 150,000 sites in the Arctic where methane is seeping into the atmosphere. The fragile and rapidly changing Arctic is home to large reservoirs of methane, a potent

Greenland's glacier meltdown gives new insight for rising sea level

Greenland's contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows. Data shows a 30% speed-up in 10 years on average. With faster movements of the glaciers, ice and

Ice melting on Lake Baikal

For several months each year, Russia’s Lake Baikal is covered by a thick layer of ice. Formation begins in late-December, and by mid-January the entire lake is usually blanketed. Come spring, the lake begins its long, slow melt. Patches of open water usually appear

Retreating sea ice around Alaska sign of advancing spring

Over the winter of 2011–2012, the extent of sea ice in the Arctic Ocean was slightly below the 1979–2000 average, but conditions in the Bering Sea were different. There, sea ice extents were well above normal, reaching a record high in March 2012. Two factors

The cold waters of Hudson Bay are typically covered with ice from January to May each year and reach reaching ice-free status in mid-August, but by early April, 2012, ice breakup was well underway across the Bay. Bits of open water covered with some floating ice can

Ice floes along the Kamchatka coastline seen from ISS

The irregular southeastern coastline of Kamchatka provokes large, circular eddy currents to spin off from the main southwestward-flowing Kamchatka current. Three such eddies are observed by the International Space Station (ISS)  as the winter season blankets

Ice cover in the Sea of Okhotsk

In late March, 2012 sea ice hugged the shores of Russia’s Sakhalin Island and covered much of the Sea of Okhotsk. As spring brings increasing sunlight to the region, the ice will begin to break up and flow out to the Pacific Ocean. On March 23, the Japanese
