I heard the current around Antarctica was tightening, meaning the atmosphere above it was also tightening it's wind structures in correlation giving wa less rain i.e. the anticyclones are intruding less into the country than they used to.

Long term pattern apparently.

Does this link http://blogs.discovermagazine.com/imageo/2016/03/29/ocean-warming-threatens-stability-of-antarctic-ice-shelves/#.Vw9Yz9R95mU correspond with that story?
