I would like to ask one more question on the Arctic.
Last summer or the previous one, I went to Prudhoe Bay, in Alaska, where there is a huge oil complex. We realized how significant climate change really is.
How do you see things with respect to how long we have to act? What effect will climate change have on managing the Arctic? Is this an emergency or do we still have a lot of time to act? Is the gradual disappearance of permafrost a risk for facilities like that in Prudhoe Bay, that may not be in a position to operate for as long as we had expected?
