And remember, the satellite data are one small part of a vast amount of data that overwhelmingly show our planet is warming up: retreating glaciers, huge amounts of ice melting at both poles, the «death spiral» of arctic ice every year at the summer minimum over time, earlier annual starts of warm weather and later starts of cold weather, warming oceans, rising sea levels, ocean acidification, more extreme weather, changing weather patterns overall, earlier snow melts, and lower snow cover in the spring...

Given that this feedback alone gave that warming input while realized AGW was between ~ 0.4 C and 0.85 C, and given that it is inherently non-linear with increasingly juvenile arctic sea ice being increasingly vulnerable to melting, it seems fairly clear (to me) that as «anthro warming» rises towards ~ 2.4 C the sum of the feedbacks» outputs would inexorably rise to offset our best efforts at Emissions Control.

While the 2010 melt season started with more multi-year ice (MYI) in the Beaufort and Chukchi seas than seen in recent years and an overall greater percentage of MYI arctic - wide, by the end of August nearly all of this MYI had melted out or ice concentration had fallen below 40 %.
