I think what Alastair is alluding to is the fact that, say by 2050 when the arctic ocean will conceivably be ice - free in the summer, the atmosphere will have a much higher relative humidity than it has currently because of the open air = water interface, so this will have a magnifying effect beyond just the feedback from increased CO2.
