Excerpt:Â (The following remarks were authored by my son, Michael Y. Harward. He had presented me the authority to publish and/or reproduce this commentary.) Mr. Gore, I do not believe there is such a thing as man-made global warming. I do not think globe warming is provable, being that we only have data for a fraction of the time the earth has been in existence. Furthermore, I do not think anyone knows the optimal climate for any part of our globe. Maybe the earth is too cool and needs to correct itself.
