I think what you're trying to say is that with the advent of climate change, and perhaps the temperature rise, two degrees would be substantial. I think probably in the last 30 or 40 years, there's been an increase of about one degree, or three-quarters of one degree, on surface water.
This is an area we intend to focus on in stage two of our LEEP, our Lake Erie plan. We'll be assessing that and we'll be focusing on that very question.
