Arctic sea ice levels to reach record low within days John Vidal, environment editor guardian.co.uk, Thursday 23 August 2012 09.11 EDT
With the melt happening at an unprecedented rate of more than 100,000 sq km a day, and at least a week of further melt expected before it begins to reform ahead of the northern winter, satellites are expected to confirm the record – currently set in 2007 – within days.
“Unless something really unusual happens we will see the record broken in the next few days. It might happen this weekend, almost certainly next week,” Julienne Stroeve, a scientist at the US National Snow and Ice Data Centre in Boulder, Colorado, told the Guardian.
“In the last few days it has been losing 100,000 sq km a day, a record in itself for August. A storm has spread the ice pack out, opening up water, bringing up warmer water. Things are definitely changing quickly.”
Because ice thickness, volume, extent and area are all measured differently, it may be a week before there is unanimous agreement among the world’s cryologists (ice experts) that 2012 is a record year. Four out of the nine daily sea ice extent and area graphs kept by scientists in the US, Europe and Asia suggest that records have already been broken.
