Arctic warming likely to reverse - scientist

The findings add another wrinkle to a problem climate scientists have been warning about since the record melt of 2007: after each summer meltback, the Arctic Ocean refreezes completely in winter. The problem is that much of that refreezing creates a relatively thin layer of so-called first-year ice. "It's weaker than thick, multiyear ice," says University of Colorado scientist James Maslanik, "and less resistant to melting."

the info comes from an accredited climatologist.

it seems that in the case of sheet ice, it's size that matters but girth (depth to be precise but it doesn't sound as rude)
