These stresses work the ice (adding heat) warming and weakening the ice allowing it to fracture and calve in ways not contemplated in models.<br /><br />How fast can the process go? It goes fast enough that most of the time we do not see it, so we do not model it.Aaronhttps://www.blogger.com/profile/05150805906414546377noreply@blogger.comtag:blogger.com,1999:blog-16612221.post-8094105395702816372014-05-14T10:13:13.960-04:002014-05-14T10:13:13.960-04:00Jim Eager:

The graph clearly states "70S to 0", yet Anthony calls it "from 70S to the pole". Sorry, Anthony, RSS does not provide any data poleward of 70S, because of the high altitude surface influence on the MSU/AMSU instruments. Anthony really needs to do his homework. Maybe then he could convince Christy and Spencer to stop presenting Antarctic data as well...<br />E.

I haven't read the paper, but my impression from past research was otherwise, i.e. that undermining would cause serial collapse of the ice front, allowing the resulting bergs to drift northward and mostly get melted there. This is actually what happens now, but much more slowly.
