The climate is always changing. Minor swings are entirely normal. In the 70's, they were warning of an upcoming ice age. Now? Global warming. The fact is this: this planet, and the entire universe, are not static. There is nothing that we can do to prevent climate change. The climate change scare mongers make a fortune off of their movies and books. It's a very profitable business. If you want to believe a meteorologist that can predict the weather correctly 60% of the time, go for it.
