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.

Last time I heard NASA was a space exploration division of the US government. Not climate experts.


In space there are planets, among which there is the Earth. NASA has had for a very long time experts on everything that regards climate (ocean/fluid dynamics expert, atmospheric physicists and chemists, biosphere and cryosphere experts, etc ...), whether it is to study Earth's climate or other planets'. I am not sure why you think there are no climate experts at NASA, but you should really be more curious about what NASA does ...

And since they are funded almost entirely by the government, do you actually expect them to go against the grain ?


Your point being that when the government was AGW skeptics, NASA scientists were skeptics too? Or does it work only one way?

Our Government has never, EVER, been "skeptical" of Global Warming. They latched onto it and started passing regulations based on it before ANY hard science was done on it. And now we see how reputable even the "hard science" has been on it. None. A fraud, a lie, 100%.

There is no such thing as a "climate expert". That's the dirty little secret climategate has exposed. No models have shown to be accurate. Hell, half the "experts" said this recent snow storm wouldn't even happen. If you can't predict what happens next week, how in the hell can you tell me what's it going to look like in 100 years ?

Who are these "climate experts" ?? Can you point me to one piece of work they have done that is relevant, useful, and beneficial in some way ?

If I went to college for 8 years for horticulture, and told you I was a "grass expert" and that if you didn't bulldoze your front lawn you were going to die, would you do it ? Of course not !! That's f'ing absurd. But for some reason you and every other sheeple gives the same power to "climate experts" ?

Just live your goddamn life and let others do the same. This issue is OVER. You have lost. You lied, cheated, ruined peoples lives, stolen untold prosperity, and in the end it all came down on your sides heads.

If you can't call a fraud a fraud after it's been exposed right in front of your own eyes, then you people deserve to be as miserable as you are.
