Global warming is a matter of serious concern today as it strongly influences weather and environment. It is caused by water vapor, carbon dioxide and other air pollutants which envelop the atmosphere of the Earth and capture the heat of the Sun. This results in the excessive warming up of Earth.

The sources of carbon dioxide which is responsible for global warming are:

• Power plants which consume coal. It is the greatest source.
• Automobiles which produce about 1.5 billion tons of carbon dioxide in a year. Global Warming Facts:
• In the last 50 years it is estimated that global temperatures have increased at an alarming rate. In fact the rate is accelerating.
• Global warming may transform hurricanes into dangerous and violent catastrophes. This happens as the oceans become very energetic because of the extra warming.
• This century can end with a high increase in temperature.

Harmful Effects of Global Warming:

Global warming is actually affecting the world in many ways. The serious ones are:

Over the ages greenhouse effect has triggered at an alarming rate because of the following reasons:

• Glaciers are melting very fast.
• Oceans are getting warmer, the sea level is gradually rising and there are floods in coastal areas.
• There are periods of very warm weather and strong heat waves.
• The warming of Arctic and Antarctic areas

Continued Global Warming can result in:

• The early arrival of spring.
• Changes in population and shifts in the range of animals and plants.
• Heavy floods, snowfalls and downpours.
• Bleaching of coral reefs.
• Fires and droughts.

Today new technologies are used, to cut down gases that are responsible for global warming.
