CLIMATE CHANGE AND DYNAMICS OF THE PERMAFROST ON SVALBARD
According to the meteorological station Barentsburg the average positive temperature of air on West Spitsbergen for the period of 1985–2011 years grows by 0,02 °C/year, and for the period of 2002–2011 it is reduced on 0,03 °C/year. The average negative temperature of air for these periods grows with...
