Back when the sea was thick and lasted for years, cyclones tended to spread the ice out and actually increase its extent, said Julienne Stroeve of the National Snow and Ice Data Center in Boulder, Colo. Now, when ice gets spread out, it simply breaks up and disappears.
“As our ice cover has thinned, some of our old rules are changing,” said Stroeve.
