The Arctic probably is the fastest warming region on this planet. It never was as apparent as this winter. Several heat waves had struck the High Arctic and temperatures rose up to 5°C above the 30-year average. This and the fact that less sea ice had been formed last year as well had led to a new record low of Arctic sea ice extent in winter. Only 14.4 million square meters of the Arctic Ocean had been covered with sea ice. The unusual warming period als has led to strange weather phenomenas on the entire northern hemisphere this winter.
