Glaciers are formed when snow, compressed into large thickness of crystalline ice mass, develops an ability to move due to sheer mass. These glaciers together with snow and ice constitute the cryosphere which covers nearly 10 per cent of the surface of the earth (NSIDC, undated). The major part of ice and glaciers is found […]

Stratospheric ozone Arctic Ozone Depletion and Impact on Climate Change A study which examined the Arctic ozone depletion at eight stations in the Arctic stipulates that the Arctic stratospheric ozone recovery, predicted for the mid 2030s, might be significantly delayed (Pommereau, 2018). The study observed that the 2015-2016 ozone depletion is the third largest reported […]
