My assumption is that we will see a continued change in the arctic sea ice pattern over the next decade. The effect on weather will be interesting to see, if the arctic isn't all that cold the annual pattern of wind and heat in the northern hemisphere will be very different; how I don't really have any idea. In a complex heat engine if you change the distribution and amount of heat it's not easy to predict what the end result will be.

Of course if we stop studying it everything will go back to normal /s.
