A large part of the Canadian ice shelf has separated from the mainland, but remained trapped in offshore ice. Apparently, it splintered away to become an ice island last August, but one fear is that it will float into oil fields. I had always imagined some threats from this kind of event, such as the ice melting and making sea level rise. The idea of the danger presented to both shipping lanes and to fixed oil platforms had not crossed my mind directly. I don't think such things are easy to control, and truly hope we don't add oil spills and further contamination of the sea to the damage we're doing it by changing the climate. The sea is already reported as sick, and it doesn't need new ailments added.
