Winds are Dominant Cause of Greenland and West Antarctic Ice Sheet Losses
Wind-induced circulation changes in the ocean are the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets, not "global warming," according to two new studies.
The first study, published in Nature Geoscience, found that there has been a rapid acceleration of several outlet glaciers in Greenland and Antarctica; most notably, Jakobshavn Isbrę, a large outlet glacier feeding a deep-ocean fjord on Greenland's west coast, which went from a slow thickening to a rapid thinning in 1997:
The second study, published in Geophysical Research Letters, focused on the delivery of Circumpolar Deep Water (CDW) to the inner continental shelf around Pine Island Bay (Antarctica). The most significant result was that temperature changes in CDW related to regional wind forcing:
- Researchers found a sudden increase in subsurface ocean temperature in 1997 along the entire west coast of Greenland, suggesting that the changes in Jakobshavn Isbrę were triggered by the arrival of relatively warm water originating from the Irminger Sea near Iceland.
- They traced these oceanic changes back to changes in the atmospheric circulation in the North Atlantic region.
- In conclusion, they predict that future rapid dynamic responses of other outlet glaciers to climate change will require an improved understanding of the effect of changes in region ocean and atmosphere circulation on the delivery of warm subsurface waters to the periphery of the ice sheets.
- Easterly winds over the shelf edge change to westerlies when the Amundsen Sea Low migrates west and south in winter/spring.
- This drives seasonal on-shelf flow, while inter-annual changes in the wind forcing lead to inflow variability on a decadal timescale.
- A modeled period of warming following low CDW influx in the late 1980's and early 1990's coincides with a period of observed thinning and acceleration of Pine Island Glacier.

But when you see men struggling to evade its existence, to misrepresent its nature, and to destroy its last remnants - you may be sure that whatever their motives, love for man is not one of them." - Ayn Rand, Capitalism: The Unknown Ideal

this line is the clue that this is the opinion/conclusion/spin of the writer, a denier not those who did the studies....shifting winds likely warmer and warmer ocean temperatures are part of climate change...Originally Posted by coyote
the concluding line from the first study is quite clear that it is global warming at work
We conclude that the prediction of future rapid dynamic responses of other outlet glaciers to climate change will require an improved understanding of the effect of changes in regional ocean and atmosphere circulation on the delivery of warm subsurface waters to the periphery of the ice sheets.

If a prediction requires improved understanding, what does that mean for the value of the prediction?
Anything will used to justified the OBSERVATIONS Except Anthropogenically Induced Global warming.
What depths will the LIARS stoop to in order to continue their destructively polluting lifestyles and deluded fascist political corporate agendas?
We all know where the WIND came from DONT WE FOLKS!

notice the sly wording implying the authors of the two studies agree and came to that conclusion...the conclusion is completely that of the writer of the piece not the researchers...
not "global warming," according to two new studies.
