Scientists anticipate that during this century, the surface temperature of the earth would probably rise by 1.1 to 6.4 degree Celsius. It is estimated that global warming would have far reaching effects across many more centuries in the future owing to the heat capacity of the oceans and large lifespan of carbon dioxide in the atmosphere. The climatic adversities related to global warming include rise in sea levels, alteration in the pattern of rain, increase in subtropical deserts, withdrawing of glaciers, extinction of various species and transition in crop production.
