Here is a link that might help since 1950 It may not have always been warmer but the temp rises as the ice melts along with the radiation of the sun as it has more darkness of the water to absorb heat http://ocean.dmi.dk/arctic/meant80n.uk.php

> You have problem with an article written by NASA which is fully referenced, provides links to the original data and can be checked online yet have no problems whatsoever with reproducing a non-referenced, non-sourced graph by a blogger with a fake name and unknown qualifications and who makes a rather odd claim not backed by any scientific research?

"I have problems with this article, they compared ice extent with previous years, but don't show what ocean warmth was in previous years." Do you suggest that the Arctic Ocean temperatures were unknown until just recently? Due mostly to the "Cold War", between the U.S. and the then U.S.S.R., there have been submarines that took samples of the Arctic Ocean temperatures since the 1940s. A lot of under ice measurements were taken by both nations. - Source: http://www.athropolis.com/arctic-facts/fact-subs.htm As far as the Arctic sea ice acts as an insulator or not depends greatly on the season. During the winter months there is very little to no direct sunlight in the Arctic region. During this time there would be no albedo effect of the sea ice. During the summer months when the Arctic region receives the sun's energy continuously then the presence of the sea ice acts as both an insulator and the sea ice albedo effect also comes into play. When the Arctic sea ice melts then the albedo effect is greatly reduced in the area since and the darker waters absorb more solar energy than they would if the sea ice was still present. This is crucial to understand. As more and more extent is being exposed to areas of less sea ice we will see more and more absorption of solar energy into the waters there. The heat content of the waters will make it more difficult for the next winter to freeze over these waters to any appreciable depth and thus making it easier to melt out with the next melt season. The thinner sea ice also becomes more impacted by the winds and currents than does the thicker sea ice that was there previously. Gringo, you nailed it!

" I explained that the Arctic receives very little solar radiation so albedo is not a big factor" The extra radiation trapped by a doubling of CO2 amounts to about 3 W/m2. A change of over 50% in the arctic albedo due to the difference in reflectivity of water vs ice is certainly significant in this regard, even with annual average of 40 w/m2 in the arctic.
