Did a 2006 Arctic “Heat Wave” Largely Cause 2007’s Sea Ice Melt?

In terms of the mechanisms restricting ice melt this season, to the extent that they have anything to do with air temperature, a cool Arctic above 80N basically means an absence of overrunning air from southern latitudes. Pretty much every temp spike up there is simply a wind spike — from the south. While warm sea water incursions probably matter significantly more than air temps when it comes to sea ice melt, air temps do for sure matter, too. As an example, maybe the best example: I don’t believe that 2007’s then-record melt could have taken place without a prolonged high-Arctic warming, wind-generated without doubt, during the first months of 2006.

When it was initially apparent that a period of mild cooling was taking place in the high Arctic one month ago, I decided to reach out to Walt Meier of the National Snow and Ice Data Center. I wanted him … Continue reading →
