Arctic Sea Ice has Already Reached its Minimum Winter Level this Year, and it isn’t even Summer Yet

As per the National Snow and Ice Data Center the ice coverage of the Arctic sea seems to be on its lowest maximum in 2015 and the yearly melt seems to set for an early beginning.

The most extreme extent of 5.59 million square miles, recorded at  Feb. 25, was lower than whatever other year’s winter greatest and 6.35 percent lower than the 1981-2010 normal, as per the Boulder- based center. Sea ice extent has inclined down since that date; ice extent generally tops around the center of March and a year ago crested on the spring equinox, March 21.

Researchers are holding up a few days prior to pronouncing that the years greatest has been arrived at, however the late decrease is striking, said Mark Serreze, director of the National Snow and Ice Data Center.

Serreze said on Monday. “We’re seeing that the most extreme will be at or close to a record low, unless something interesting happens in the following two weeks, which it could.”

The decline isn’t essentially a marker of an exceptionally huge summer melt-off, Serreze said.

The areas where sea ice is especially low this winter – the Bering Sea and Russia’s Sea of Okhotsk – are ranges where ice typically melts out in summer at any rate.

“It’s not quite clear what the low extent starting out the melt season is going to portend for the health of the ice,” he said.

Winter satellite estimations are not about as noteworthy as those in the mid-year and fall, Serreze said. The satellite pictures demonstrate simply the extent of the ice, not its age, thickness or quality, he brought up. The best sign of ice wellbeing comes in September, after a season’s melt, he said.

Still, this present winter’s freeze-up insights are intriguing, he said, astoundingly amid a year when the plane stream has been moving in unordinary ways, bringing frosty and frigid climate to the U.S. East Coast and warm weather to Alaska and the U.S. West.

Serreze said he doesn’t see a confirmation that reductions in sea ice firmly impact the jet stream, as is speculated by some atmosphere researchers. Anyhow sea ice vanishing is most likely one of numerous elements bringing about the winding example that has brought abnormal climate to wide regions, he said.

“What changes in ocean ice can do is, basically, stack the craps,” he said.

Arctic sea ice extent arrived at its lowest record on Sept. 16, 2012, when it dwindled to 1.32 million square miles, the least since satellite estimations started in 1979. A year ago regular low was 1.94 million square miles, essentially higher than in 2012 yet at the same time the sixth-least in the satellite record. The six least yearly Arctic ice minimums have happened in about eight years.

    Weird that NOTHING is mentioned of the Antarctic, which is doing the opposite of the Arctic – record ice growth. Climate change theory says they should both be melting, but no one told the Antarctic.

      @Barry – perhaps they are only talking about the Arctic because the info is from the “National Snow and Ice Data Center” ya think?

      Meanwhile Antarctic ice is ALSO loosing volume, just not near as much as the Arctic and Greenland.

      What’s really funny is that my prior email pointing out that using “Minimum” in the title is a mistake has been somehow “lost”(?)
