If they do so by simulating near - average conditions most of the time, they are getting the right answer for the wrong reason, and their predictions of future sea ice decline should be discounted.

This is substantially lower than the earlier estimates, reflecting both lower than average sea ice extent used as initial conditions this summer and a persistent downward trend in sea ice extent over the past decade (and longer).
