Negative impacts of green house effect

1. First, there is expansion of ocean water and increase in the ocean level due to the melting of ice caps.
2. Warming up of water means a higher rate of evaporation which results in greater amount of water vapor content in the atmosphere. Because the latent heat of condensation is the main energy source for the atmosphere’s circulation this leads to a more vigorous hydrological cycle.
3. In some areas, there may be heavy rainfall while in others there may be no rainfall. So, there is possibility of frequent and intense flood and droughts too.

Floods and droughts are the most devastating natural agents that may lead to death, misery and economic damage. It could be more devastating than any other impacts.
