Mr. Speaker, Canadians are concerned. They are certainly concerned about climate change. In terms of the 2° warming, we have to look carefully at the data and there is reason for some debate. We thought spring had arrived a couple of months ago and it has not. We are seeing climate variability for sure. We are seeing instability and that is typical when climate is changing, as it has changed in the past. We go through periods of instability. We are seeing later springs and winters are not quite as cold. We have a very cold spring, for example. As we experience climate change, we are seeing all kinds of variabilities.
When we deal with complex models, multiple variables and incomplete data, our understanding of these processes will be advanced as more data becomes available.
