Global warming has become perhaps the most complicated issue facing world leaders. On the one hand, warnings from the scientific community are becoming louder, as an increasing body of science points to rising dangers from the ongoing build-up of human-related greenhouse gases — produced mainly by the burning of fossil fuels and forests. On the other, the technological, economic and political issues that have to be resolved before a concerted worldwide effort to reduce emissions can begin have gotten no simpler, particularly in the face of a global economic slowdown.
Greenhouse gases are “include water vapour, carbon dioxide, methane, nitrous oxide, and ozone components of the atmosphere that contribute to the greenhouse effect. Some greenhouse gases occur naturally in the atmosphere, while others result from human activities
In the United States, on Jan. 2, 2011, the Environmental Protection Agency imposed its first regulations related to greenhouse gas emissions. The immediate effect on utilities, refiners and major manufacturers will be small, with the new rules applying only to those planning to build large new facilities or make major modifications to existing plants. Over the next decade, however, the agency plans to regulate virtually all sources of greenhouse gases, imposing efficiency and emissions requirements on nearly every industry and every region.
President Obama vowed as a candidate that he would put the United States on a path to addressing climate change by reducing emissions of carbon dioxide and other greenhouse gas pollutants but still thinking.....
India is one of the most vulnerable countries when it comes to effects of global warming The Himalayan glaciers have started to melt and the average rate of retreat is almost twice (34 metres) per year as compared to the 1971 levels of 19 metres. The melting glaciers will cause temperatures and sea-levels to rise and there will be a cascading effect on the crops and the monsoons. Worse – whole islands are expected to vanish! In fact two have already gone under – two islands in the Sunder bans (an area which India shares with Bangladesh). Temperatures in the group of islands has already gone up by one degree centigradestal line and the rising sea levels caused by global warming will cause an ecological disaster.
In fact, as far back as 1993 a study to evaluate the impact of rising sea levels on India was carried out by JNU (Jawaharlal Nehru University). They calculated what would happen if the sea-levels rose by just 1 metre…and they found that as many as 7 million people would be displaced and 5,764 sq km of lain September 2002, scientists at the National Centre for Agricultural Economics and Policy Research conducted a people’s perception survey on climate-induced natural disasters in the Kendrapara-district of Orissa. The results showed that the frequency and intensity of droughts have increased and so have the incidents of flooding. Also, the intensity of cyclones has increased and people believed that the sea-water had become warmer.
These poor villagers do not know why this is happening .!!!!!!!!!
Global Warming. Ironically these poor villages hardly contribute to global warming…they hardly emit any greenhouse gassing and 4,200 km of roads would be lost! And not roads every time lives are more important than roads...for sure and it is something to be seriously considered.
As of these increasing disaster every human is to rise for the prevention material as for now if this is just some interesting record, later would be something predestine that turn over his future.
