Composition and Structure of the Atmosphere — Question 12

The gradual increase in average temperature of the Earth and change in climate pattern is called Global warming. It occurs due to greenhouse effect of gases like carbon dioxide, methane and CFCs.

The consequences of 'Global Warming' are:

1. Melting of ice caps and Glaciers.
2. Increasing sea temperature is wiping out coral reefs. These are breeding ground for many marine species and they protect coastlines from storms.
3. It may pose serious threat to the ecological balance.
4. Higher wildlife extinction rates.
5. Higher sea levels.
6. Global warming is increasing the frequency and severity of many types of disasters, including storms, heat waves, floods, and droughts.
