Global Warming

Introduction

Man is atrociously burning carbon reserves , causing carbon dioxide concentration in the atmosphere that has risen by 30 per cent since the Industrial Revolution . The earth has not experienced such concentrations for the last 750 ,000 years , according to scientists . A NASA study states that Greenland Ice Sheet was retreating by one meter in 2001 now the rate is 10 meters a year . If the Greenland Ice melts , the sea level will rise by six to seven meters . The effects of climate change should

be considered as great a threat to biodiversity as the "Big Three " - habitat destruction , invasions by alien species and over exploitation by humans . The broad conclusions are very solid , and very sound , and very alarming . The 2002 abnormally heavy rains and devastating floods that cost Europe 16 billion loss and many deaths are attributed to climate change so also the damage to 10 ,000 properties involving one billion Pound Sterling in insurance claims and 30 ,000 deaths in 2003 during the heat wave in Europe

Climate is the average pattern of weather over the long term . For millions of years the Earth 's climate has cooled or warmed . The phenomenon is not new but our knowledge that human activity affects the Earth 's climate is new . Scientists , environmentalist , even filmmakers and fiction warn us that the global climate is warming threateningly .Several animal and plant species will not survive the climatic changes . Up to 37 per cent of them would disappear by mid-21st century . Scientific assessment of Arctic climatic impacts shows that Arctic temperatures have risen by nearly twice the global average over the past fifty years and will rise 4 ?C to 7 ?C by 2100 . The rise in Arctic temperatures is dangerously impacting on human and wild life From Russia to Canada , buildings collapsed due to subsidence caused by thawing of permafrost , Polar bears and seal fell victim to this climatic disaster . These two countries belatedly ratified the Kyoto Protocol under this climatic threat

The Treat

Over the past century the global temperature increased by 0 .6 ?C to 0 .7 ?C . The 1990s were the hottest and 1998 the hottest year since the records began in 1861 . Eight hottest years since 1861 belonged to the 1990s . Glaciers everywhere are receding and sea levels rising . The 20th century recorded 10 cm to 20 cm rise in sea levels snow cover diminished by 10 per cent . Carbon dioxide levels , currently the highest are rising . Environmentalists do not believe that geographical phenomenon like the , El Nino caused this baneful increase . They blame human activity

Report of IPCC

There can be no room any more for skepticism on global warming "The warming of the climate system is unequivocal , as is now evident from increases in global average air and ocean temperatures , widespread melting of snow and ice , and rising global mean sea level " says a report of the Intergovernmental Panel on Climate Change (IPCC ) released on February 02 , 2007...
