Global warming or climate change has become a worldwide concern. It is gradually developing into an unprecedented environmental crisis evident in melting glaciers, changing weather patterns, rising sea levels, floods, cyclones and droughts. Global warming implies an increase in the average temperature of the Earth due to entrapment of greenhouse gases in the earth’s atmosphere.
There is a crying need to raise awareness about global warming if we have to save the world from disaster. Here we are providing you some useful articles on global warming under various categories according to varying words limits.
Life sustains on Earth by depending on the energy coming from the sun. About 60 percent of the energy and light reaching the Earth surface passes through the air and vapors where the harmful gases get segregated and absorbed. These gases are radiated upwards in the form of infrared radiation. About 90-92 percent of this infrared radiation is then received by the greenhouse gases and reflected back to the earth’s surface. Due to the ozone layer depletion and global warming, the greenhouse effect has become the primary reason for which the Earth surface now radiates more heat than it usually should.
