Atmospheric temperature should be much higher to make continental glaciers melt, said the head of Science and Research Institute of Arctic and Antarctic Regions Ivan Frolov.
      
      “Many hundred years or 20-30 degree temperature rise would have made glaciers melt”, says the scientist. Today Greenland’s and Antarctic glaciers have the tendency to grow.
      
      Scientists have two opposite points of view concerning Earth’s climate – global warming and global cooling. Mr. Frolov says cooling and warming periods are common for our planet – temperature fluctuations amounted to 10-12 degrees. However, such fluctuations haven’t caused glaciers to melt. Thus, we shouldn’t be afraid they melt today.
