A clear example of how difficult the arctic waters are

As I wrote a month ago "Arctic waters are a hotspot for emerging risks. We have tough ice conditions, possible new transport routs, oil and gas reserves, unresolved regional disputes and military strategic areas. Each of these conditions has unique and new challenges difficult on their own".

Now (reported by several sources, see for example the Economist blog) the arctic challenges has hit Shell, and their operations in Alaska, so hard that they already now say that there will be drillings this year. They plan to be back next year.

The problems Shell are having is off course a very clear example of how difficult the arctic waters are and how little we still know about them.
