There was a good study at WCRP which showed that much of the inter annual variability is wind related, as ice is moved towards the Atlantic in certain years.
I don't know if It's in print yet. Veli has made this point before, and the modelling seems to support his view. This is worrying, as It's a non thermal process. SRM can't predictably change the wind, so unless we can rapidly rebuild the ice to a continuous mass, it will tend to get blown away when the winds dictate.
