One of the biggest effects of global warming is the rising of the sea level. The reason for this is the melting of the polar ice caps, causing the rise of the sea level, and threatening the low lying coastal areas and cities causing them to flood. Those countries include Egypt, the Netherlands, and Bangladesh. Moreover, some other countries may even disappear completely out of the face of the earth. Scientists assumed that the warmer the temperature in the sea, the higher it rises. However, the heat causes the water to expand and when the ocean expands more space is taken up. An instance of the melting is the entire coast of Florida. The coast is threatened by rising seas and stronger surges during storms.
