Sea level rising

The sea level rising which caused by global warming is now causing flood. The warming of the atmosphere caused by greenhouse gases melting the glaciers and rising the sea level.

Sea level is rising rapidly than what scientists are predicted. Warmer temperature is raising the sea level by expanding ocean water, melting mountain glaciers and melting parts of the Greenland ice sheet. Ice is melting worldwide, especially at the earth's pole which includes mountain glaciers and ice sheet.

It could causes flooding of low lying coastal areas and cities such as Egypt, the Netherlands and Bangladesh. Some countries might even disappear completely. Also the islands somewhere like Bahamas,Barbados and Barbuda are in danger because sea levels are raising fast and these islands are very flat. Therefore the flood could cover the island very fast.

Many cities have been destroyed already. In Bangladesh it is almost totally destroyed. Lots of people died and have been forced to move their places to other because of flooding. Sea level rising also can cause saltwater intrusion. It can intrudes into groundwater, drinking supplies and contaminates irrigation supplies. Also low lying coastal areas are very easy to become contamination of freshwater.
