The Arctic will be ice-free in summer within 20 years

"Ships will be able to sail in open water to the North Pole in the summer of 2020, according to a study that found a rapid acceleration in the loss of sea ice."
The Arctic will be ice-free in summer within 20 years, the study found, while the Earth will lose the white cap that can be seen in photographs taken from space.
“The North Pole will be exposed in ten years. You would be able to sail a Japanese car carrier across the North Pole and out into the Atlantic,” Professor Wadhams said.

This has several consequences, such as:
1. Without ice to reflect sunlight, the Arctic Ocean would warm more quickly, resulting in the release of greenhouse gases
2. The warming of the Arctic surface waters would accelerate the melting of the Greenland ice sheet, speeding up the sea level rise.
