Arctic sea-ice levels at record low for June
Sea ice in the Arctic has melted faster this year than ever recorded before, according to the US government's National Snow and Ice Data Centre (NSIDC). Satellite observations show the extent of the floating ice that melts and refreezes every year was 318,000 square miles less last week than the same day period in 2007, the year of record low extent, and the lowest observed at this time of year since records began in 1979. Separate observations by University of Washington researchers suggest that the volume of Arctic sea ice is also the smallest ever calculated for this time of year.
