From
NSIDC here at the University of Colorado in May, 2008:
Could the North Pole be ice free this melt season? Given that this region is currently covered with first-year ice, that seems quite possible.
From the
UK Met Office this week:
. . . the first ice-free summer [is] expected to occur between 2060 and 2080. It is unlikely that the Arctic will experience ice-free summers by 2020.
Climate whiplash is a one good reason why efforts to motivate action should not be built on the backs of predictions.
