Global warming has become a important issue today..and more of a worry.! Lot of scientist across the world.. is searching for all the information regarding the global warming. 
The North Pole and the predictions regarding the north pole.. is a big worry for the scientist and as well as for the people around the world.
It seems our worst fears may come true. For the first time in the human history, ice is on course to disappear entirely from the North Pole this year.
Its expected that “North Pole may be ice free for the first time this summer”.
Firsthand, observations and satellite images show that the immediate area around the geographic North Pole is now mostly annual, or first-year, ice—thin new ice that forms each year during the winter freeze.
Such ice is much more tends to melt during the summer month, in comparison to perennial, thick and dense ice, that has lasted through multiple cycles of thawing and freezing.
IF it happens, it raises the prospect of the Arctic nations being able to exploit the valuable oil and mineral deposits below these a bed which have until now been impossible to extract because of the thick sea ice above.
The normally think ice formed over many years at the pole has been blown away and replaced by huge swathes of thinner ice formed over a single year. The rate of melting is faster than last year, when there was an all time record loss of summer sea ice at Arctic.
Scientists are particularly interested in the North and South Poles because they are expected to show the most dramatic effects of global warming.
Models predict that the regions will see temperature increases roughly three times as quickly as the rest of the globe because of an effect known as ice albedo feedback, which occurs when highly reflective ice gives way to dark water.
The water absorbs much more of the sun’s energy, increasing temperatures and causing further ice melting.
Each summer the sea ice melts. But the last year, the loss of sea ice was so extensive that much of the Arctic Ocean became open water, with the water ice boundary coming just 1126.5 km away from the North Pole.
This means that about 70% of the sea ice present this spring was single year ice formed over last winter. Scientists predicts that much of the ice will melt this summer causing a global warming.
Here’s where the extent of sea ice in the Arctic stands now in relation to the average tracked between 1979 and 2000, and the remarkable ice loss in 2007:
Thus, all the data’s clearly figure out the extending ice on the poles.. and the knocking of global warming with the meting of ice on these poles. This clearly results, in the temperature change and thus effecting the climatic conditions as well..!!!!
well.. lets wait and see when we can go through the clear image of this warming. Its expected not to reach by before 2013 to 2030.!
Thus, the global warming is not so far. And this can be easily visible in these , videos describing all the aspects of global warming and the melting of ice… on the North Pole.
