Northwest Passage fully navigable

Thanks to Global Warming, Northwest Passage (The most direct shipping route from Europe to Asia) is fully navigable now. In just over a year the ice cover has dropped by about 386,000 square miles. Quoting BBC:

"We have seen the ice-covered area drop to just around 3m sq km (1.2m sq miles)," Leif Toudal Pedersen of the Danish National Space Centre said.

He said it was "about 1m sq km (386,000 sq miles) less than the previous minima of 2005 and 2006".

"There has been a reduction of the ice cover over the last 10 years of about 100, 000 sq km (38,600 sq miles) per year on average, so a drop of 1m sq km (386,000 sq miles) in just one year is extreme," Mr Pedersen said.
