Just 12 MIles to Go

That is all the distance that remains between a huge crack in the Larsen C ice shelf and the open Southern Ocean. [photo: MIDAS project] When the crack reaches the edge, an ice berg the size of Delaware will float into the ocean.  The Larsen already floats on the ocean, but it is buttress against land-based glacial flows entering the sea that will further elevate sea levels. Globally sea levels have risen about eight inches since 1901.  Antarctica, which holds 90% of the Earth's fresh water, is losing 92 billion tons of ice per year, and the rate of loss has doubled from 2003 to 2014.

Mr. Trump, the future of planet Earth is now. The seventy mile crack grew another eleven miles in December alone [photo, right].  The rapid growth of the crack in a short period of time convinces scientists a calving event is near.  The Larsen C already produced a huge collapse in 2002 of over 1200 square miles, but this even will release an incredible 3100 square miles of ice cap.  The shelf has been deteriorating since the early sixties when photographic record-keeping began.
