    Cassandra,

    Where does the half as thick # come from? Last year the ice massset a new low, but not by a large margin. You got a link for me?

    Thanks.

    The comparison is to the mass of 2007, not 2008, but still very much back of the envelope.

    ccpo, seems my back-of-the-envelope estimate was conservative, see here:

    I will be posting the abstract of the Kwok and Zwally article when available.
