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

Coastal erosion caused by rising sea level is greater than previously thought

The anticipated rise in sea levels due to climate change will result in coastlines receding worldwide through erosion. Rising sea level inundates low-lying areas, converts wetlands to open water, erodes beaches, exacerbates flooding, and increases the salinity of

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

Sealife faces risk of large-scale extinctions

Global warming and acidification of the oceans are associated with three of five largest planetary extinction events of the past 500 million years. Loss of oxygen  in seawater, pollution, loss of animal's  habitat, overfishing and overhunting are to blame for ongoing

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

Ancient Egypt: Study augments the drought theories

Recent research testifies archeological records of droughts in Ancient Egypt during the demise of Egypt's old kingdom, the era known as the pyramid-building time. A study of ancient pollen and charcoal preserved in deeply buried sediments in Egypt's Nile Delta provides

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

Scientist proposed cloud engineering as response to global warming

A controversial idea about shooting salt water high into the sky over the oceans to create clouds that reflect sunlight, is now reconsidered again in order to battle global warming. Rob Wood, physicist at University of Washington, proposes an experiment to test the...

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

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.
