Even though the sea
ice declines slowly, the majority of winter warming is due to that loss.

In contrast, the scenario in Fig. 5A, with global warming peaking just over 1 °C and then
declining slowly, should allow summer sea
ice to survive and then gradually increase to levels representative of recent decades.
NSIDC Research Scientist Walt Meier said, «While the
decline of the
ice started out fairly
slowly in spring and early summer, it accelerated rapidly in July.
Concensus AGW science predicts «X» as a consequence of «A.» But that doesn't mean it has to happen — it's still possible that AGW is sound but there something quirky about the Arctic that they missed, or that the changes will happen more
slowly than expected, so it won't warm faster than the globe and / or sea
ice won't
decline.
For now, our temperatures will continue to
slowly decline until we reach the back end of the Galaxy, which will result in massive amounts of energy being drawn from our system and we enter another
Ice Age.
In contrast, the scenario in Fig. 5A, with global warming peaking just over 1 °C and then
declining slowly, should allow summer sea

«Arctic sea
ice extent
declined quite
slowly in April; as a result, total
ice extent is now close to the mean extent for the reference period (1979 to 2000).»
This is not because there was not thicker winter sea
ice near Iceland (there was), but because that was more than compensated by sea
ice losses in less accessible areas so that overall sea
ice extent
declined in that period (albeit,
slowly):
As this column has sometimes pointed out ways in which the effects of global warming are happening more
slowly than predicted, it is fair to record that this rate of
decline in Arctic sea
ice is faster than many predicted.
