Ice meltdown in North Pole

September 3rd, 2009

We all know that Arctic is the cold icy region around the North Pole. During the last few years, many headlines have appeared in various newspapers, journals, magazines and reports that the North Pole is warming up, as a result of which, the ice over the Arctic region is melting down continuously. In the year 2005, Arctic received the least amount of ice reported in the last century. The satellite images taken recently show big openings in the perennial cover of ice. This is also considered to be a major consequence of global warming. Global warming refers to the increase in the average temperature of the entire earth.

Condition of the native animals
Because of the Ice meltdown in North Pole, the native animals of that region including the polar bears are encountering potential threat for existence. This is because these animals depend upon the sea ice for their survival and in the event of ice melting down, they do not get the cold temperature that they need for living. Polar bears use to travel across this ice for hunting the seals and with less ice on the sea, polar bears face difficulty in finding their food and thus their survival is quite tough. Researchers sway that if the sea ice continues to disappear, the animals that depend upon ice will face greater risks of extinction.

What causes the ice meltdown in the Arctic region?
The thick perennial ice of the sea typically survives the warm summer months and last throughout the year. But the recent satellite images show that up to 10% of the ice has been cracked due to the summer storms. This surprising change involves a region bigger than the British Isles. According to the scientists, humans being are only responsible for global warming, which is the major cause of ice meltdown in the Arctic. We drive cars, use electricity and burn fossil fuels like natural gas, oil and coal.

Effects of ice meltdown
Burning of the fossil fuels gives out gases, which trap the heat from sun. This causes a significant increase in the temperature all across the world. Unlike Antarctica, which is a completely ice-covered continent, ice on the North Pole rests on the top of an ocean and that is why it is susceptible to even a small level of global warming.
Soot that is emitted from incompletely burned fuel in factories and car engines is also a major accelerator of the Arctic ice meltdown. Ozone, dark carbon and methane are the major perpetrators of ice meltdown in North Pole and according to the researchers; these accelerate the melting down more than global heating and sunlight.
Some studies also state that ice meltdown in North Pole is not only the result of global warming and soot, but it is also part of some natural phenomena.

Things at the North Pole are changing very fast and the entire world is going to be affected. Some scientists say that the Arctic Ocean may become ice-free during summers within a period of 10-20 years and this may pose a tough challenge for our existence in the next 50-100 years.
