State the effects of greenhouse gases on the atmosphere.

Effects of the greenhouse gases on the atmosphere are :

1. Greenhouse gases are crucial for the evolution of life on earth. Without them, solar heat would escape, leaving the planet cold and barren like the moon.
2. They are necessary for evaporation of water and formation of clouds, leading to rain.
3. The increase of greenhouse gases above an optimum level is causing global warming by increasing the earth's temperature.
4. Global warming due to greenhouse gases will lead to rise in sea level, change in rainfall pattern and destruction of forests and wildlife.
