'GLOBE' - WARMING FASTER
'GLOBE' - WARMING FASTER
Scientist have warned that the North Pole could be ice-free by 2013 instead of 60 years as predicted earlier. The matter was based on computer studies of satellite images that reveal that ice at North Pole melted at an unprecedented rate very recently. The scientist have observed that the ice is clearly not building up enough over winter to restore cover. A SOS call has come from the marooning Pacific Island nations to take immediate actions to cope with the impact of climate change in the region. The island countries are already being effected by increasing extreme weather events such as cyclones and loss of fresh water supplies because of pollution by sea water. Now is the time for concrete action over climate change. United Nations are establishing an Inter-Agency Climate Change centre with Pacific country of Samoa to combat the impact of global warming in their region.
- Global warming has resulted in a increase of the average surface temperature, a decrease in snow cover and ice extent and a rise of the sea level.
- Birds have been shifting towards the North due to change in the climate. According to a study in Britain, 42 rare bird species from Southern Europe, like the Dartford warbler, Cirl bunting, little egret or Cetti's warbler had become more common in Britain from 1980-2004. According to Britain Huntley of Durham University and the Royal Society for the Protection of Birds, the species, mentioned above, are almost responding to the climatic change. The study tried to filter out other factors that would affect the counts of the rare birds, including public interest in bird-watching. Shifts in farming, pollution, expansion of cities have all affected wildlife. Birds and butterflies are among the first to adapt to the change in climate because they can fly far-off distances in search of cooler habitat.
- Chunk of ice separated from the Ward Hunt Ice Shelf off the north coast of Ellesmere Island in Canada's far north. According to the Canadian officials, there is a chunk of ice about seven square miles (18 square kilometers) in size broke off from the largest remaining ice shelf. In a development consisting the climate change theory, the enormous icy plain broke free and began slowly drifting into the Artic Ocean. This icy piece was a part of the shelf for 3,000 years. A small crack in the shelf was first spotted in 2000. The crack-riddled section of ice was like a jig-saw puzzle. Ellesmere Island was once entirely ringed by a single enormous ice shelf that broke up in the early 90's.
- Draining of wetlands hasten climate change. Draining of wet and marshy lands for farming purposes could be contributing to climatic changes. Wetlands such as marshes, swamps, mangroves, peat bogs and river floodplains covers six (6) percent of the earth's land surface, and store up to twenty (20) percent of terrestrial carbon in the form of slowly decaying organic matter.
- Extreme Whether events, a cause for global warming cannot be denied. Extreme whether events such as Hurricane Katrina, East Asian dust storm, Drought in Australia, floods in lowa and China, etc. We are experiencing the effects of a more unstable climate : altered drought and rainfall patterns, more intense storm, more temperature extremes and so on.
