Contemporary changes in the area of glaciers in the western part of the Nordenskjold Land (Svalbard)
Climate warming in Svalbard, starting in the 1920s, caused a signifcant reduction in the mountain glaciation of the Nordenskjold Land. Te most extensive changes took place in the Western part of this territory due to the influence of the warm Spitsbergen current creating here the high temperature bac...
