Global warming will have both negative and positive effects. A new study suggests that global warming will open up a first time chance to cruise through the Northwest Passage. Estimates say traversing the North Pole by ship could be done in just over 14 days. NOAA is so confident of open sea water during the late summer months by mid century, that plans are being made to issue new navigation maps. The above photo shows the present day shipping channel controlled by Russia. The map below shows proposed new open routes by the year 2040 or 2050.
No part of the world has seen as much dramatic warming in recent decades as the Arctic. Since the 1980s, average temperatures in the region have risen faster than the global average. Last September, sea ice extent has seen by satellite reached the minimum since such records began in 1979.
