“An international team of scientists has launched an expedition to drive the Northwest Passage on sea-ice this spring, marking the first time the Passage has ever been travelled in a road vehicle.”
“An international team of researchers led by Mars Institute scientist Dr. Pascal Lee successfully reached the arctic community of Cambridge Bay, Nunavut, Canada on Friday, 17 April, after an 8-day, 500 km vehicular trek on sea-ice along the fabled Northwest Passage.”
“Independent researchers analysing long term trends of these indicators, have seen an increase in air, sea and land temperatures, rising sea-levels, and decreasing Arctic sea-ice, spring snow cover in the northern hemisphere and glacier extent.”
“Meanwhile, the U.S. Geological Survey announced on September 16th that the 2008 summertime Arctic sea-ice melt was the second greatest on record, nearly matching the extraordinary melt of 2007.”
“We've seen a tendency for autumns with low sea-ice cover to be followed by a negative Arctic Oscillation.”
“Satellite measurements showed summer sea-ice cover in 2009 was more than a quarter below the average amount between 1979 and 2000, scientists in one study concluded.”
“Satellite measurements of winter multi-year ice cover in the Arctic Ocean between 2004 and 2008, along with the corresponding downward trend in overall winter sea-ice volume, and switch in dominant ice type from multi-year ice to! rst-year ice.”
“It appears that strong winds are causing much of the loss of Arctic sea-ice:”
“Or, we could add while speculating about "positive feedback," the added heat absorption caused by the melting of reflective Arctic sea-ice still covering dark water.”
“Moreover, sea-ice reductions can speed the entry of POPs trapped in Arctic Ocean ice into the food chain, posing risks to humans .”
