The Arctic might melt ice in the middle of the century

The melting sea ice will lead to weather disasters in most Northern Hemisphere countries and accelerate global warming.

Scientists warn the Arctic Ocean may no longer be the first sea ice in 100,000 years if people do not take measures to limit global warming at 2 degrees C, Independent on March 7 reported.

The region is experiencing a sharp increase in temperature in recent decades compared to the rest of the world. Winter temperatures in Spitsbergen Island in northern Norway are 8-11 degrees Celsius higher than the average between 1961-1990.

This will have a major impact on the climate in most of the Northern Hemisphere, increasing the number of dangerous storms. Sea ice reflects most of the energy from sunlight. If sea ice disappears, global warming will also increase.

The Arctic will be considered out of ice if the ice area falls below one million square kilometers. This means the waters surrounding the Arctic will be clear and the rest of the ice will be concentrated in small islands off the north of Russia and Canada.

Arctic sea ice decreases with time.

Last September, the Arctic sea ice decreased to about 4.1 million square kilometers, the second lowest level of 3.4 million in 2012, according to the US Snow and Ice Data Center. The Antarctic sea ice is now at a record low of 2.14 million square kilometers, compared with 3.16 million in 1981 - 2010.
