Global Warming

INTRODUCTION


Global Warming has been described as the biggest environmental threat facing homoity. People fear potentially ruinous consequences but there has been a lack of understanding well-nigh the global warming and what can be done about it.
Global warming happens when the acress temperature increases, even by a small amount, that happens naturally which is also contributed by human activity. In 1961 a British scientist did an experiment showing that the degree centigrade in the air was absorbing some of the suns radiation. Afterward a Swedish scientist, Suante Arrhenius, found out if the radiation of the sun was pin down in the carbon dioxide the temperature of the earth would increase by 1-2 degrees. In 1988 James Hanson, a respected scientist, told the U.S. Congress the greenhouse entrap is occurring now and its changing global climate. It was the industrial revolution and overpopulation of domain that was the cause of the environmental problems that we have today (Koral 1989).

BODY (GREENHOUSE EFFECT)

greenhouse force-out sees that both natural and manmade gases which ar released into the earths aureole, subsequently causes the planet to heat up, thus increasing the temperature.



First, the sun that shines on the Earths surface is absorbed and then radiates back into the atmosphere as heat. So, now some of these gases are trapped in the greenhouse, while the rest of the gases escape back into the space. The study heat trapping gases found in the atmosphere are; carbon-dioxide and water vapor, which are found in large quantity. Ozone, methane and azotic oxide, which are better heat trappers but found in smaller quantity, CFCs and PFCs, which are very(prenominal) potent and destroy ozone (Christopher Spence 2005). This is the global warming problem
Therefore, the more(prenominal) gases in the atmosphere, the more heat get trapped. Now what keeps the earth in a livable climate is the greenhouse effect says Joseph Fourier (1824):...If you want to get a full essay, order it on our website: Ordercustompaper.com
