Many people in the maritime transport industry is thinking about the possibilities of using the shorter northern passage to go and come from Asia. Even the north pole could be reachable by 2050 with a small icebreaker. This can be considered a positive consequence? I think so, as it will make easier, shorter, cheaper and less carbon intensive to transport many goods in the northern hemisphere.For climate change itself the negative impact is much bigger than the positive as the albedo, or reflectiveness of the ice is greater so more sun energy will be absorbed.
But above all, in my opinion, it is agreat prove that something really important is changing in our planet in spite of all skeptics comments, because the ice shells are a first order displays of the heat content in our planet surface. The averages of the temperatures measured in many weather stations over the world are not so easy to see but a clear ocean in the north pole is something very very expressive. What will skeptics invent then? Will they still be skeptics then?
