The Arctic may be ice-free during summer within the next 20 years, claims a new research.Now, ships will be able to sail through the ice-free Arctic in the summers. Ships traveling to Europe from the East would be able to save on journeying over 3000 miles to avoid the icy Arctic. The Arctic Ocean will warm rapidly due to the lack of ice to reflect sunlight, and the warm Arctic water will accelerate the melting of the Greenland ice, which will help the rising sea levels.
