Mr. Speaker, the comments that have been presented are interesting. Yes, a lot of those facts are well known. When we study the history of climate, the history of this continent of ours and the history of the world, we can find isolated incidents such as the heat waves in the 1930s and the dust bowls in central North America such as those that occurred in the United States and in the Prairie provinces. There is no doubt that we can isolate those kind of events.
However, this is not what I am concerned about. I am concerned about the overall and overwhelming evidence of a consistent, ongoing, consecutive pattern that is emerging now on a more frequent basis than ever in the history of the globe. Those concerns, plus all the other factors regarding those forms of behaviour, the machinery, the agricultural practices and a host of other causes that help to create the kind of atmosphere which we have to cope with at the present time, raise the level of concern among the intelligent people of the world who know that something has to be done. We cannot put our heads in the sand and bury ourselves there because there was a heat wave in 1935.
