“Another Arctic Sea Ice Milestone“. Anthony Watts is trying to milk the Arctic Sea Ice Extent blip (aka “weather”) for as long as possible. Of course this is only possible with the Nansen Environmental and Remote Sensing Center’s NORSEX estimate, which uses a slightly broader definition of sea ice. Anthony tells us about a sensational “milestone”:
Today it is encouraging to see the NANSEN is reporting that both Arctic Sea Ice area and extent are above the normal line.
What’s actually happening is that the 2010 sea ice extent has tracked previous “low” years until an early March cold snap in the Bering Sea delayed the onset of retreat. After that delay, it’s right back on the same trajectory.
But keep sayin’ it, Anthony.
