This accelerated deep ocean warming is also unprecedented in the past 50 years.
Not exact matches
At the same time as the surface is cooling, the
deeper ocean is
warming, which has already
accelerated the decline of glaciers in the Amundsen Sea Embayment.»
«At the same time as the surface is cooling, the
deeper ocean is
warming, which has already
accelerated the decline of glaciers on Pine Island and Totten.
Their argument goes like this: It is not possible that
warming of the
deep ocean accelerates at the same time as
warming of the upper
ocean slows down, because the heat must pass through the upper layer to reach the depths.
There was an interesting study in Nature Geoscience last Sunday showing pretty clearly that the
accelerating flow of the Jacobshavn glacier in recent years was most likely driven by an influx of
warm deep seawater, and that shift was likely due to changes in pressure and wind patterns over the North Atlantic
Ocean.
This suggestion of an
accelerated warming in a
deep layer of the
ocean has been suggested mostly on the basis of results from reanalyses of different types (that is, numerical simulations of the
ocean and atmosphere that are forced to fit observations in some manner).
But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long
deep freeze» — but rather a short - time span where human - caused
warming might be partly offset by
ocean cycles, staying at current record levels, but then followed by «
accelerated»
warming where you catch up to the long - term human - caused trend.
This ties in to our previous posts noting that global
warming is
accelerating; but that over the past decade, most of that
warming has gone into the
oceans (including the oft - neglected
deep oceans).
Still a lot of work to be done, and a
deep -
ocean observation system would be desirable but, as Balmaseda (2013) has demonstrated, the observations show that global
warming has actually
accelerated over the last 16 years.
