Arctic Ice Makes Comeback From Record Low, but Long-Term Decline May Continue

Sea ice in the Arctic Ocean underwent a sharp recovery this year from the record-low levels of 2012, with 50 percent more ice surviving the summer melt season, scientists said Friday. It is the largest one-year increase in Arctic ice since satellite tracking began in 1978.

The experts added, however, that much of the ice remains thin and slushy, a far cry from the thick Arctic pack ice of the past. Because thin ice is subject to rapid future melting, the scientists said this year’s recovery was unlikely to portend any change in the relentless long-term decline of Arctic sea ice.

“I’m not at all surprised there was a jump upward — we’ve never set two record lows in a row,” said Walt Meier, a NASA scientist who has monitored sea ice for years. “I would say I’m a little surprised the jump is as big as it is.”
