WHY THE ARCTIC BEING IS WATCHED UNDER A MICROSCOPE?
The Arctic has become the global warming’s victim. This region is found to be very sensitive and maximum affected by global warming. This has turned the attention of most scientists towards it. The scientists are analyzing the various effects of global warming on Arctic region.

2. WHAT ARE THE EFFECTS THAT THE ARCTIC IS UNDERGOING NOW?
Compared to the various places in this globe, the average temperature in the Arctic region is doubling up. Due to this drastic temperature rise the Arctic ice is getting melted & becoming thin day by day. For instance, the largest single block of ice in the Arctic, the Ward Hunt Ice Shelf, has been unaffected for around 3,000 years before it started cracking in 2000. Less than 2 years it got spited, now it started even to break down into pieces.
The total polar ice cap is contracting. From the images sent by satellites it’s crystal clear that the solid ice in Arctic region is melting at the rate of 9 percent per decade. If the same trend is maintained, by the end of the century one won’t be able to find ice in the Arctic region.
3. HOW WILL THE DRASTIC ICE MELT AFFECT THE ARCTIC?
The native people, wildlife and plants are already being affected this drastic melting of ice. When the Ward Hunt Ice Shelf broke, the extraordinary freshwater lake which was enclosed in it & its sole ecosystem drained into the ocean. Polar bears, whales, walrus and seals are altering their feeding and relocation patterns, thereby making it difficult for native people to hunt them. If this continues then the entire villages along Arctic coastlines has to be uprooted. This is due to the fear of getting flooded. Also the native people of the Arctic feel global warming as a greatest threat to their civilization and their survival.
4. WILL ARCTIC ICE MELT EFFECT BE FELT AWAY FROM THE POLAR REGION?
Yes -- the reduction in the Arctic ice cap is increasing global warming. Normally a shielding layer is formed over the Arctic region. This shielding layer is made up of snow and ice. When that shielding layer melts, there’s greater amount of sunlight absorbed by the earth there by becoming hotter.

Tremendous increase in the temperature has already affected the Alaska forest by increasing the growth of pests. These pests grow faster in warmer conditions. It was found that these pests have fed around 3.4 million acres of forest in one decade from 1993 to 2003.
Melting glaciers and land-based ice sheets has contributed to increment in the sea levels, bullying low-lying areas around the earth with beach erosion, coastal flooding, and contamination of freshwater supplies. Mainly the island nations are at greatest threat as more than half of their population lies in the region which is just 6 feet above the sea level, e.g. Maldives. Even few key cities like Shanghai and Lagos are likely to face similar problems.

5. Can anything be done to halt global warming?
Yes. To generate electricity and power our vehicles, we gut fossil fuels like oil, coal and gas. This in turn produces the green house gases that cause global warming. The more we burn, the faster will be the rate of global warming. From this it’s clear that all we have to do is to conserve energy.
And we can do it. Technologies has improved allot today that make cars that run and burn less gas, generate electricity from wind and sun, modernize power plants, and build refrigerators, air conditioners and the buildings that utilizes less power. This all can be more effective if every individual contributes his level in saving energy and thereby halting global warming.
