It doesn't seem surprising to me that GCM simulations don't give
useful decadal predictions on regional scale (or at least they are just beginning to get to the point where decadal scale predictions have useful skill IIRC).
«Pretending that extrapolating an observed trend or that CMIP5 simulations will produce
a useful decadal prediction of sea ice is pointless (well there is a potential point but it is to mislead).»

Claims then that this kind of
decadal prediction is
useful for policy - makers or scientists thus remain very premature.
