Historically, the earth has worked in cycles of hot and cold. When the dinosaurs lived on earth, it was much hotter and muggier. Then there was the most recent ice age. We are currently still warming from that ice age. Many scientists believe that. They believe that man-made climate change is ridiculous.
I guess you'll need to slap some cuffs on me if you really want that law passed, because I honestly don't believe in man-made global warming.
While we're at it, Holocaust denial is a myth too. No one actually DENIES the entire Holocaust. They QUESTION bits and pieces of the official story of what happened during the Halocaust. No one denies that the Jewish people and others were treated horrifically during that time. They deny certain practices that, in their opinion, didn't happen. If you start thinking for yourself rather than being a sheep, you can see their argument. Agreeing with it is your own decision, but the world would be a better place if we were more open to other viewpoints and more willing to question what we're told. Do I agree with it? Not necessarily, but it is a good argument backed up by pretty reasonable evidence, conclusions, theories, and so on.
However, as I step off my soap box, I do believe that we need to treat the planet better, not because of climate change, but because of the damage to the ecosystem. The earth has proven it has ability to correct the wrongs that happen to it. Nature adapts or it dies. We really don't want to incur that sort of wrath.
