Prepare a brief speech on global warming, you have to deliver the speech in your class.

Global warming is one of the greatest challenges that our planet is facing as we have been facing the continuous rise in the average temperature of the Earth’s climate system.

It occurs as a result of an increased release of greenhouse gases in the atmosphere. These gases, like carbon dioxide, methane, and water vapor in the atmosphere, trap solar radiations released back by the Earth. 

There are many reasons for it. One of them is increase in population. Increase in the number of vehicles is also one of the causes. 

Pollution of air has also increased the global warming. Cutting trees, grazing the plants by animals increase the global warming.
