A recent map of North Atlantic currents shows warm, subtropical water being ferried far into the northern latitudes. The increased water temperature has enabled fast sea ice and glacier melt in recent years.  (Source: Jack Cook, Woods Hole Oceanographic Institution)
Warmer ocean currents are driving Greenland's glacial melt.

It remains to be seen exactly how much mankind understands the science of climatology. While global climate models continue to be produced, disproved, corrected, and debated in the administration, there is still some solid research being done. And that research keeps showing that there's a possibility that climate science is missing large tracts of data it needs.

Recently 
DailyTech reported on research concerning the Bering Strait and how this comparatively small geological formation might be responsible or at the least involved in the regulation of the North American temperature via ocean currents. Oceans have been understood to partially control temperatures and overall climate for years, but marine science has only recently been getting any media time with all the political hubbub over the global climate change debates.

A multi-institutional research team, led by Fiamma Straneo, a Woods Hole Oceanographic Institution physical oceanographer, has been studying ice loss in Greenland, particularly in the Sermilik Fjord, which connects the Irminger Sea to the Helheim glacier. The last decade has seen accelerated ice loss in Greenland -- the Helheim glacier has already retreated by several kilometers.

Unfortunately, the area has not been monitored regularly for long enough to perfectly reconstruct the ice melts before the recent accelerated melt, but a combination of ship and moored survey data, combined with temperature and depth data taken from the radio collars of hooded seals in the area have allowed them to piece together just how quickly things can change.

They found that changes in the North Atlantic ocean currents have been bringing much warmer, subtropical water further and further north. Water as warm as four degrees celsius was found during the time data. That warm water combined with swift current propagation has enabled the massive uptake in Greenland's glacial ice. The warmer water quickly moves through the fjords, taking away with it the melted ice and keeping the temperatures relatively warm.

Straneo explains, "This is the first extensive survey of one of these fjords that shows us how these warm waters circulate and how vigorous the circulation is. Changes in the large-scale ocean circulation of the North Atlantic are propagating to the glaciers very quickly — not in a matter of years, but a matter of months. It's a very rapid communication."

She goes on to stress how little is known about ocean-glacier interactions and that continuous observation will be extremely important in coming to a full picture of how they affect each other and sea-level regulation. It is also likely that understanding how these entities cooperate will help understand how the ocean currents and sea ice as a whole may affect regional and global climates. A rapid influx of cool, fresh water could serve to disrupt the global ocean current system, known as the Ocean Conveyor even as the area appears to be warming.

"Did you even read your own link?"

Did you? Let me quote the parts you conveniently left out.

quote:
. However, new research, including work by British scientists, is casting doubt on such claims. Some even suggest the world may not be warming much at all.

The temperature records cannot be relied on as indicators of global change ,” said John Christy, professor of atmospheric science at the University of Alabama in Huntsville, a former lead author on the IPCC.
Or this, by another scientist:
quote:
We concluded, with overwhelming statistical significance, that the IPCC’s climate data are contaminated with surface effects from industrialisation and data quality problems. These add up to a large warming bias,” he said.
Or this, by a third scientist:
quote:
Terry Mills, professor of applied statistics and econometrics at Loughborough University, looked at the same data as the IPCC. He found that the warming trend it reported over the past 30 years or so was just as likely to be due to random fluctuations as to the impacts of greenhouse gases. Mills’s findings are to be published in Climatic Change, an environmental journal.


To the Daily Mail's credit, they report BOTH sides of the debate, unlike our American papers, which push the fraudulent idea of "consensus" by refusing to interview any of the thousands of scientists who dissent.

As for Trenberth's idiotic remarks, a rise in sea level doesn't prove the earth is getting warmer. He apparently hasn't heard of the concept of thermal inertia...which explains why snow is melting right now in front yard, even though the temperature is declining as night approaches.

When Trenberth can explain that, he'll understand why his remarks are all wet.
