Extraits
« The rate of decline through the month of May [2010] was the
fastest in the satellite record »

« [since last winter] Temperatures were 2 to 5 degrees Celsius (4 to 9
degrees Fahrenheit) above average across much of the Arctic Ocean. »

« Ice extent measurements provide a long-term view of the state of Arctic
sea ice, but they only show the ice surface. Total ice volume is critical
to the complete picture of sea ice decline. »
