Global warming may or may not be a fact, but our modern media and politicians have blown it out of proportion because it is the flavour of the month, much as healthcare in Canada was before it, terrorism before that and 9/11 before that. Global warming is not the apocalypse that many are making it out to be, it is part of natural cycles that have occurred on earth for millions of years, which any anthroplogist will be able to tell you. I don't deny that humans are exacerbating the situation with the methodologies that we use, but living species on the planet will adapt to changing circumstances as they have done so for millions of years also...or perish. Darwin called it.
