The article was based on an announcement made by Professor Wieslaw Maslowski, who, at the time, told an American Geophysical Union meeting that previous projections had underestimated the processes now driving ice loss.
Summer melting that year reduced the ice cover to 4.13 million sq km, the smallest ever extent in modern times.
"Our summer ice removal projection for 2013 does not account for the recent minima in 2005 and 2007," explained the researcher from the Naval Postgraduate School in Monterey, California, to the BBC.
"So given that fact, you can argue that maybe our projection of 2013 is already too conservative."
"My claim is that the global climate models underestimate the amount of heat delivered to the sea ice by oceanic advection. The reason is that their low spatial resolution actually limits them from seeing important detailed factors.”
"We use a high-resolution regional model for the Arctic Ocean and sea ice forced with realistic atmospheric data. This way, we get much more realistic forcing, from above by the atmosphere and from the bottom by the ocean."
Analyzing potential future scenarios using supercomputers has been and still is a key aspect of climate science.
Professor Maslowski's group, which included co-workers at NASA and the Institute of Oceanology, Polish Academy of Sciences (PAS), is well known for producing modeled dates that are ahead of other teams.
