> I ran across a paper I thought could be of interest to Azimuth climate network people: ["Deep ocean early warning signals of an Atlantic MOC collapse"](http://onlinelibrary.wiley.com/doi/10.1002/2014GL061019/abstract). It uses a climate network approach, using methods developed in earlier work (["Interaction network based early warning indicators for the Atlantic MOC collapse"](http://onlinelibrary.wiley.com/doi/10.1002/grl.50515/abstract) and ["Are North Atlantic multidecadal SST anomalies westward propagating?"](http://onlinelibrary.wiley.com/doi/10.1002/2013GL058687/abstract)).
