Arctic sea ice dips to record low for winter
Giving a strong signal of a global warming, the Colorado-based National Snow & Ice Data Center has announced that extent of floating ice in the Arctic region hit a new low for winter.
Arctic Sea ice hit this year a record low wintertime maximum extent of 5.57 million square miles. That is nearly 35,000 square miles below 2015’s record low.
Sea ice floating around Antarctica also slipped to its lowest extent at the end of summer in the Southern Hemisphere. In February 2017, the combined sea ice extent in the two regions was at its record low since 1979.
Satellite images suggested that total polar sea ice covered nearly 16.21 million square kilometers, which is 2 million sq. km. less than the average global minimum extent recorded between 1981 and 2010.
Sea ice scientist Walt Meier of NASA’s Goddard Space Flight Center, said, “It is tempting to say that the record low we are seeing this year is global warming finally catching up with Antarctica.”
Most scientists say increasing carbon emissions are responsible for the global warming that is being blamed for melting ice at the poles. However, President Donald Trump and other Republicans don’t believe so.
