http://en.wikipedia.org/wiki/List_of_rivers_of_RussiaThe Yukon is often stated as a Arctic River, but in flows into the Bering Seas and thus the main push of its water is into the Pacific. For the Fresh water to enter the Arctic it must past through the Bering Straits.
The Mackenzie River is the largest river that flows into the Arctic from North America, its discharges, 9,700 cubic metres per second of water into the arctic (Average volume)
http://en.wikipedia.org/wiki/Mackenzie_RiverCompare this to the top Three Russian Rivers, all provide more water:
Ob, 12,500 m³/s
http://en.wikipedia.org/wiki/Ob_RiverLena 17,000 m³/s
http://en.wikipedia.org/wiki/Lena_RiverYenisei 19,600 m³/s

The Islands to the North of Canada blocks MOST the the flows from these small rivers from flowing North. Thus most of the Water getting into the Arctic is from Russia. In fact if you look at these rivers, they start in the Himalayans and flow NORTH. They seem to have kept Siberian from having the Ice Sheet North America had in the last ice Age, now they are melting the Arctic Ice Cap.
My point is that why is the Arctic melting more on its Russian Border then the Canadian/Alaskan. Greenland Side? The Greater flow may be enough, but is increased temperature in Siberia also a factor? Just an observation of WHY the Arctic is melting the way it is.
