Daily Kos: Confirmed: Ocean circulation patterns changing.:
"The Greenland ice cap is melting so quickly that it is triggering earthquakes as pieces of ice several cubic kilometres in size break off. ... Robert Correll, chairman of the Arctic Climate Impact Assessment, said in Ilulissat today: 'We have seen a massive acceleration of the speed with which these glaciers are moving into the sea. The ice is moving at two metres an hour on a front 5km [3 miles] long and 1,500 metres deep.
That means that this one glacier puts enough fresh water into the sea in one year to provide drinking water for a city the size of London for a year.' ... He had flown over the Ilulissat glacier and 'seen gigantic holes in it through which swirling masses of melt water were falling. I first looked at this glacier in the 1960s and there were no holes. These so-called moulins, 10 to 15 metres across, have opened up all over the place. There are hundreds of them.'"
