Absolutely. As I said in my opening remarks, it was not unexpected by the scientists. Knowing what happened in Antarctica, they anticipated that this was possible in the Arctic. This past winter was the first time it was verified with scientific evidence that we had a hole. It was a very sizable hole. When you have a hole, more UV radiation makes it to Earth, which is a concern for all of us. The hole in the Antarctic is predicted to resolve, and so is the hole in the Arctic, but you always want your monitoring to confirm what you're predicting.
