No Ice in Arctic?

I find I'm reading more and more articles that seem to point to some date within 10 to 50 years when there will be no ice at all in the arctic in September of that year. I think when this occurs(if this occurs?) actually I think it is when and not if at this point that major changes will begin to occur worldwide after this point. This would be much like how fast a paper cup of soda pop with ice in it gets warm once all the ice melts on a warm day.

One of the many problems is that though white ice reflects the sun, blue water absorbs the sun and thereby raises the water temperature considerably in the arctic and this in turn will cause a speedup of arctic warming and multiple changes in weather on earth.
