The cloud cover are likely not a forcing and thus a cause of warming but more likely a positive warming feedback. (realclimate.org)
A knowledge of sea ice extent is important because ice cover has a strong albedo warming feedback. (www-das.uwyo.edu)
Blooms of algae in the Arctic Ocean could add a previously unsuspected warming feedback to the mix of factors driving temperatures in the north polar regions up faster than any other place on the planet, according to the authors of a new study in Proceedings of the National Academy of Sciences.
