The following are the major risks in Asia apprehended from climate change:
There is some evidence of increase in the intensity or frequency of some of extreme weather events like heat waves, extratropical and tropical cyclones, prolonged dry spells, intense rainfall, tornadoes, snow avalanches, thunder storms, dust storms etc on regional scales in widely separated areas of Asia throughout the 20th century.
Arid and Semi-arid Asia
Possible changes in area-averaged surface air temperature over Asia and its sub-regions as a result of future increases in greenhouse gases. Numbers in parenthesis are area-averaged changes when direct effects of sulphate aerosols are included.
