Global Warming is one of those disasters created by man which can destroy our world within a strick.

It is very dangerous situation for us now . Due to our modernization and technology development this problem has created.

We will experience a great change in our climate , topography because of this . We will have to face famines . Because it is said that our glaciers are melting die to its effect. Our tropical areas will suffer from Flood problems. The deserts will be more dry . We all have to suffer for our life .


There is no solution at this instance. We are going for our slow extinction. But humans are very curious and innovative creatures . We must thought out of ideas how we could stop it .

If we are the best creatures on Earth , we have to prove it by solving this great problem. Now it's challenge for all of us .

HEYA FRIEND....

Good morning friends...Today i am here to tell something about global warming...hope u all listen it carefully and enjoy it...

Global Warming is when the earth heats up (the temperature rises). It happens when greenhouse gases (carbon dioxide, water vapor, nitrous oxide, and methane) trap heat and light from the sun in the earth’s atmosphere, which increases the temperature. This hurts many people, animals, and plants. Many cannot take the change, so they die.

Many reasons may be there for the Global Warming, Primary and main cause is considered to be the Green House Effect. This effect is mainly caused by Carbon Dioxide, Methane, Chlorofluoro Carbon, Nitrous oxides etc gases. These gases form a cover in the atmosphere around the Earth through which hot rays of the Sun can enter to the Earth but cannot exit. So, the heat of the Sun remains in the lower circle of the Earth making the temperature rise.

It is feared that the world may experience rise in temperature of about 4° to 5°C by 2050. The average temperature of the Earth has risen by about 1°C in last five centuries and of this half of the warming is caused in Twentieth Century alone. The Global Warming is increasing at an alarming rate.

Global warming is affecting many parts of the world. Global warming makes the sea rise, and when the sea rises, the water covers many low land islands. This is a big problem for many of the plants, animals, and people on islands.
