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.

You still have not produced a report to cover the real question that would need to be addressed be for taking action... We all know the planet is changing what we do not know is why it is changing other than history shows that the planet climate does change from time to time. So, showing snow has increased and decrease on certain mountain is not the answer.. Even your third article states:

"Human Responsibility for Climate Change
The report finds that it is “very likely” that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century."

I can sum that up in just a few words THEY DO NOT KNOW. That is why they say "very likely", they can not prove it. This is the evidence I would need. There is evidence of pollution in the sea from us dumping garbage in the sea. We made the garbage, we dump the garbage, so the pool of garbage is our fault, nothing to debate.
Now I read your articles very fast (skimmed) so maybe I missed these areas. However, termites in South America produce more CO2 then all the human on the planet... Your articles do not talk about them. We have more Volcano's going off right now in last hundred years, then in other hundred year blocks. Each one of the volcano's put out in 1 day to 7 days the amount of CO2 that all mankind puts out in a year. Again your articles do not address them either. There is just so much more data that would need to be gathered before you can even try and guess the effects man is having on the planet verse what the planet is doing to itself. Remember the Earth has been doing this type of changes for billions of years. It's the planets way of cleaning it's self. So, it may be time for us to use the money that is going to stop global warm and use it towards something smart, like creating builds to help mankind live through the next ice age which maybe only a few decades away... Otherwise maybe mankind will repeat history and be wiped out like the dinosaur.
