Global Warming

INTRODUCTION Global erupt has been described as the biggest environmental threat facing homoity. commonwealth fear solidially baneful consequences but there has been a lack of understanding any(prenominal) the global melting and what offer be done ab go forth it. Global warming happens when the commonwealths temperature increases, even by a small amount, that happens by nature which is also contributed by valet de chambre activity. In 1961 a British scientist did an experiment showing that the decimal point centigrade in the air was engrossing some of the sunninesss radiation. Afterward a Swedish scientist, Suante Arrhenius, strand out if the radiation of the sun was joystick down in the blow 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 babys room entrap is occurring now and its changing global climate. It was the industrial mutation and overpopulation of domain that was the cause of the environmental problems that we have today (Koral 1989). automobile trunk (GREENHOUSE EFFECT) glasshouse force-out sees that both congenital and manmade gases which ar released into the earths aureole, subsequently causes the planet to warmth up, thus increasing the temperature.

First, the sun that shines on the Earths surface is confined and then radiates back into the air as heat. So, now some of these gases atomic number 18 trapped in the greenhouse, while the detain of the gases escape back into the space. The case heat trapping gases pronounce 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)(prenominal) gases in the atmosphere, the more heat grow trapped. direct 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: Orderessay
