Political institutions encode, enshrine and manage the application of social power. Politics is the institution that legitimizes all the others. Because of its unique ability to make laws and its access to the legalized violence that defends those laws, politics is the fullest expression of the power hierarchy of modern civilization.

Mauri: Thanks for that explanation. But it does beg the obvious question. To what extent will rising sea levels accelerate glacial flow? Seems like a nice little positive feedback loop there.

We understood the concept, were not mystified in 1980's and published papers as such documenting the physics behind the acceleration of marine terminating outlet glaciers. The problem has been quantifying this. The basics have been reviewed here. http://www.realclimate.org/index.php/archives/2008/04/moulins-calving-fronts-and-greenland-outlet-glacier-acceleration/#more-550 Summary, ice thins at termius, the terminus floats more, restraining pressure of bed and fjord walls is reduced, glacier speeds up, calves more, thins more, until the glacier reaches a new point where restraining forces balancing the calving forces a the glacier front. The Jakobshavns effect was coined by Terry Hughes at the U of Maine in the 1980's who was the advisor to Pfeffer and myself. This process has been demonstrated to be the real deal for acceleration of the ice sheet not the increased melt rate. As one of the glaciologists examining glacier flow in Greenland.

At least that will give the media a chance to get climate change back in the news. In the UK the bad news about the economy has pushed environmental issues right off the agenda.
