North Pole is melting records in record history, even in winter

Recently, scientists have found ice at the north pole of the record levels recorded in the history of the thinnest. In fact, it occurs during the winter there, and even more surprising, when the winter cold is more than that recorded last year. However, the liquidity of ice was still higher than the rate freeze.

Prior to this, in the northern polar ice has melted at a high level in the summer to create a new inland route.







New water routes created by melting ice

According to Walt Meier of National Snow and Ice Data Center in Colorado, the total amount of ice at the North Pole has declined by 10% compared to that recorded in 2007. In fact, based on observations from NASA's 30 years ago also showed the trend of decreasing the amount of ice that is consistent. This once more proves that our planet to global warming.

However, Jay Zwally of NASA's Goddard Space Flight Center believes if a longer winter occurs as expected this year, a new layer of ice that will emerge and reach a thickness that can weather the coming summer. 'Ice of the Sea requires 7-8 years to reach a thickness of up to 5 meters.

However, if the trend decline in the amount of ice is going on, he predicted the North Pole will be ice-free zone in the summer by the year 2013.

What will happen when there is no ice at the north pole?

Ice sheet is very useful to the Earth because it works with the sun reflecting of heat into space while maintaining the temperature of sea water below the ice surface. Without the ice, ocean water is exposed to heat and thus raise the temperature of sea water.
