Global Warming

INTRODUCTION Global Warming has been described as the biggest environmental threat facing homoity. People fear impregnableially perverting consequences but there has been a lack of understanding to the highest stage the global warming and what can be done closely it. Global warming happens when the acress temperature increases, even by a small amount, that happens naturally which is also contributed by human being 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 reefer 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 glasshouse entrap is occurring now and its changing global climate. It was the industrial alteration and overpopulation of domain th at was the cause of the environmental problems that we have today (Koral 1989). carcass (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 automatic teller machine as heat. So, now some of these gases ar trapped in the greenhouse, while the rest of the gases escape back into the space. The rent heat trapping gases found in the atmosphere are; carbon-dioxide and water vapor, whic h are found in large quantity. Ozone, methan! e 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 than(prenominal) gases in the atmosphere, the more heat lead off 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: BestEssayCheap.com
