The total volume of Arctic sea ice fell to a record low in 2010, according to a new study. Scientists at the Polar Science Center of the University of Washington estimated that last year broke the previous 2007 record for the minimum volume of ice, which is calculated from a combination of sea ice area and thickness.
Axel Schweiger of University of Washington, led the study. According to the scientists, ice volume is now plunging faster than it did at the same time last year when the record was set. The Arctic sea ice area fell below 4.6 million sq km recently, compared with the record low of 4.13 million sq km in 2007, whereas the minimum ice extent in the early 1970s was 7 million square km.
