What I can say, certainly, is that this is one of those circumstances where what Dr. Tarasick had published was about the ozone hole in the Arctic. It was very clear from a lot of media questions that the questions were going to be about ozone monitoring and what we're doing, which it is not the responsibility of Dr. Tarasick to respond to. When we had the media say they were going to stick to the science of the paper, Dr. Tarasick did do a media interview. When the question strayed into the policy realm, Dr. Tarasick appropriately didn't respond.
