Yes, environmental change is absolutely making search and rescues more common, and the actual execution of those searches more difficult. Again, changing ice conditions, changing conditions on the land and changing turning seasons, all of these have led to increases in the number of searches across Nunavut, but it's also other things. It's loss of land, safety knowledge and traditional knowledge that is having an impact here. More severe weather is also linked to environmental change. There's a lot going on in this space to drive up the number of searches, not the least of which, of course, is increased outside activity.
Calvin's search and rescue group in Cambridge Bay actually has been quite busy rescuing ecotourists who are skiing between Cambridge Bay and Gjoa Haven, which I think is a really good example of some of the new pressures that are put on the SAR system by increased outside activity.
