The Antarctic Wilkins Ice Shelf hangs by a thread. Its thinnest point is now reported at 500 metres wide and it could go at any time according to David Vaughan, a glaciologist with the British Antarctic Survey. This will be the tenth shelf lost because of a warmer planet. Look folks, the 'debate' on climate change is over and we cannot afford to sit idly by while 'observing the effects' (an analogy to Nero comes to mind). In the name of national security, it's past time to move beyond lip service by making plans to adapt and prepare ourselves.
