Despite Major Melt, Arctic Sea Ice Will Miss Record Low

As the sun begins its seasonal descent in the Arctic sky and temperatures drop, the summer melt of sea ice is slowing down.  In the next few weeks, the span of the Arctic Ocean covered by ice will reach its annual low.

But despite beginning the summer at unprecedentedly low levels, this year’s minimum won’t break the stunning record of 2012, experts say, thanks to cloudy weather that slowed the rate of melt.

Depending on how the weather plays out over the next few weeks, that minimum is likely to fall somewhere between second and fifth place, they estimate — still a remarkably low level that shows how precipitously sea ice has declined in recent decades.

“There hasn’t been any recovery in any ice at all,” Julienne Stroeve, a senior scientist at the National Snow & Ice Data Center, said.
