Interesting. Perhaps the real cause of increased summer ice melt is the reduction in cold fresh water reaching the Arctic Ocean following the damming and diversion of many large rivers in North America and North Asia for agriculture.
I recall some articles on cyclical current shifts taking water from northern Russian rivers in different directions. Under some current conditions, that fresh water moves east toward the Berring Strait which is a natural chokepoint keeping fresher water in the Arctic making ice formation a lot easier. In the current conditions, that water is flowing west toward the North Atlantic where it disperses more easily and is a smaller influence on a much larger body of water.
