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.

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.

The trend from 2001 is NEGATIVE, not positive.

What does the "trend" from 2001 has to do with your statement that "the world stopped warming 15 years ago"? If it demonstrates one thing it is that you have serious ADD going on ... are you capable of following a discussion for more than 2 sentences, seriously?? That's not even mentioning that while the 15 years positive trend is not quite statistically significant yet, your 9 year pseudo trend is a statistical joke. I guess you missed that point too ...

From 1995, the trend is so weakly positive as to be statistically meaningless.

The trend from 1995 is 0.12 C/decade, to be compared to a longer term value of 0.16 C/decade or a model-projected value of the order of 0.15 C/decade (give and take depending on scenario and model). That isn't weak, by any stretch of imagination. The not "statistically significant" does not refer to the fact that the trend is so weak that it does not count (it is not), it refers to its calculation not being in the 95% confidence interval. It appears now that you totally misunderstood what it means for a calculated trend to be statistically "significant at the 95% significance level". Seriously, you should read stuff like that before engaging in conversion on topic you know nothing about:

or check this figure in particular that shows you why the trends from around 1995 are not statistically significant:

The phrase "there has been no statistically significant warming of the planet in 15 years" is accurate. Period.

Correct, this phrase is accurate ... but your phrase "people like Phil Jones [...] are admitting that the world stopped warming 15 years ago" is a just bull from someone who does not begin to understand what statistically significance means ... period.

You also conveniently ignore the fact that GW modelers predicted strong and rapid warming from 2000-2010. Instead, the only data we have shows a negative trendline. Care to explain that one away?

I don't ignore anything, it's just it has not been discussed yet. I could indeed care to explain you what individual model runs and ensemble averages tell you about underlying long term trends and short term natural variability, but considering your obvious intellectual shortcoming on basic notions such as the ones previous discussed, I won't even bother.
