Global Eutrophication Process and Its Peculiarities in Arctic Lakes as a Result of Climate Warming

The problem of eutrophication of water objects as a global process is analyzed. The volumes of increasing planetary use of N and P, the dispersion of which together with climate warming leads to an increase in the nutrient content of lakes and rivers, are shown. The results of original studies of remote lakes of the Arctic zone are provided. The tendency toward an increase in the contents of N and P, as well as organic matter in water lakes even in case of the absence of anthropogenic impact, is revealed. It is proved that the climate warming mostly affects the increase in the nutrient content and the trophic status of lakes.
