Unlike the Antarctic which has a landmass to limit heat flow, the Arctic is a land locked body of water, subject to shifting ice due to weather--it will of course be subject to more variation. However, by virtue of it's landlocked nature, heat flow from warmer waters is limited. For this reason it will never be ice free. All the climate models have been proven wrong. Personally, I'd like to see the Arctic essentially ice free, so I can sail there. But it won't happen except in rare intervals for very short periods of time. The North Pole will have an ice cap for millions of more years--until the continents open up warmer waters to the region.
