Antarctic sea ice grows to all-time record high

While we are seeing decline of Arctic sea ice, Antarctic sea ice hit its annual winter maximum on September 22, 2014 reaching a record area of 20.11 million square kilometers (7.76 million square miles). The National Snow and Ice Data Center (NSIDC) announced on

WMO dubbed last year as disturbing sign of climate change

The World Meteorological Organisation revealed in Statement on the Status of the Global Climate, that during the August to September 2012 melting season, the Arctic’s sea ice cover was just 3.4 million square kilometres (1.32 million square miles). That

IceBridge: Keeping a close eye on Jakobshavn glacier

Jakobshavn Glacier, one of the fastest moving glaciers in Greenland, has been the focus of IceBridge survey flights for five consecutive years. Here, images from an IceBridge mission on April 4, 2013 and video footage from the 2012 Arctic campaign show this rapidly

Beginning of Arctic sea ice melting season

The average extent of sea ice in the Arctic has begun shrinking and will probably reach its minimum extent sometime in mid-September. Arctic sea ice reached this year's maximum extent on March 15 at 15.13 million square kilometers (5.84 million square

State of global temperatures in 2012

According to the World Meteorological Organization, the first ten months of 2012 indicate that it will most likely be the ninth warmest on record (since records began in 1850), despite the cooling influence of La Niña early in the year. The presence of a La Niña

Antarctic sea ice cover is increasing under the effects of climate change

Antarctic sea ice drift caused by changing winds are responsible for observed increases in Antarctic sea ice cover in the past two decades according to new study by British Antarctic Survey and NASA. While Arctic experienced dramatic record ice loss due the climate

ESA satellites observing sea ice

As reported earlier this year, Arctic sea ice is thawing at an unprecedented rate. News is perturbing, provided that heat exchange between sea and atmosphere is largely influenced by sea ice. Thermal flux, the rate at which heat energy transfers, can change

Arctic sea ice shrinks to smallest extent ever recorded

Rate of summer ice melt smashes two previous record lows and prompts warnings of accelerated climate change. Arctic sea ice cover likely melted to its minimum extent for the year on September 16, according to scientists at the National Snow and Ice Data Center

Arctic sea ice at lowest level on record

The amount of sea ice in the Arctic has fallen to the lowest level on record. On August 27, Arctic sea ice was at 4.10 million square kilometers (1.58 million square miles), or about 30 % of the Arctic Ocean’s surface according to the National Snow and Ice Data

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

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

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

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

Arctic sea ice hits record low

The extent of the Arctic sea ice — has passed a new threshold. German researchers announced on Sept. 8 that the sea-ice cover had shrunk below its record minimum, set in 2007. Elsewhere, researchers said the race remained too close to call.The NSIDC proclaimed the

Large variations in Arctic sea ice

For the last 10,000 years, summer sea ice in the Arctic Ocean has been far from constant. For several thousand years, there was much less sea ice in The Arctic Ocean - probably less than half of current amounts. This is indicated by new findings by the Danish National

A colony of emperor penguins disappears

A small colony of emperor penguins on an island off the West Antarctic Peninsula is gone, and the most likely culprit is loss of sea ice caused by warming. Although it has been predicted that penguins could suffer greatly because of global warming, this is the first
