Introduction to global warming
Global Warming: Global warming refers to the increase in average temperature of the earth, particularly at the lower atmosphere due to the abundant increase of greenhouse gases. This is primarily due to the human's intervention and the lifestyle they have adapted in the recent years. Greenhouse gases in its natural content in the atmosphere are required, for it acts as a greenhouse around the earth. It allows the sun's rays to pass through the atmosphere but doesn't let it to escape and creates a surrounding suitable for life. Life cannot exist without green house gases like carbon dioxide, water vapor, methane etc but they should be existing in permissible quantities only. The problem of global warming arises when people started contributing abundant amount of green house gases which traps more heat in the atmosphere thus increasing the temperature. Global warming begins when sunlight reaches Earth. The clouds, atmospheric particles, reflective ground surfaces and ocea...
