Wind and waves scatter sea ice, not AGW

Antarctic sea ice

Antarctic sea ice can be breathtaking.

Waves chase away warming

A paper has arrived from NIWA that says, in effect, warming is not necessary to explain the disappearance of much sea ice. That it removes a warming element from the polar pieces of the global warming puzzle gives me great pleasure. Well done, them!

I’m talking about “Storm-induced sea-ice breakup and the implications for ice extent” (Nature 509, 604–7), published online in Nature on 29 May, by A.L. Kohout, M.J. Williams, S.M. Dean and M.H. Meylan (KWDM). Its major discovery is that large waves travel much farther through pack ice than hitherto realised, thus breaking up much more ice than we realised and allowing it to be swept away by wind and wave—it hasn’t been melting from the heat of global warming.
