Global warming has led to increase in mean earth surface temperature and thus melting of polar ice. There are frequent melt down of glaciers that result in floods and other natural calamities. The melting of ice at the poles had led the mean sea level. And further increase in temperature may further melt the ice and lead to further increase in mean sea level, which will engulf low lying countries.
The effect of global warming is very evident on the animal kingdom also. Some animals have become extinct due to loss of their natural habitat or their inability to evolve to the rapid changes in the climate. Also there is a change in their life style because of the changes in the seasons. The migrating birds have changed their time of travel and also their place of migration.
The effect of global warming can be felt on seasons too. There is shift in season cycle, as the summers are getting longer than the winters. This has affected the animals and made them to change their lifestyle accordingly, and those who failed to do so have perished or on the verge of extinction. Global warming is also responsible for the introduction of some new diseases. The bacteria are more effective and multiply much faster in warmer
temperatures compared to cold temperatures. The increase in temperature has led to increase in the microbes that cause diseases. Global warming is also effecting the crop production, as the crops are getting destroyed by the sudden change in temperatures or sudden on set of rains. Also the flash floods and other natural calamities affect the crop.
The earth's atmosphere is getting more unpredictable with heavy rains in the areas, which have scanty rainfall or drought in the areas, which received good annual rainfall. The schedule of rainfall months has also been affected.
