-- a note from kt75 A number of recent studies on the towing of arctic sea-ice report new all-time lows of ice coverage [ 1 ]- [ 4 ]. Similar effects have been reported previously for glaciers, e.g. in the Swiss Alps [ 5 ], [ 6 ]. The global warming (climate change) has been identified as one of the primary reasons for the reduction in ice-coverage with obvious consequences, e.g. for regional and local weather conditions. In addition to this economic implications are expected as well [ 7 ]-[ 9 ]. Further readings: [ 1 ], [ 2 ], [ 3 ], [ 4 ], [ 5 ], [ 6 ], [ 7 ], [ 8 ], [ 9 ] kt75 : http://kt-75.blogspot.ch/
