However, as Mr. Tyson has said, we're going to see more and more extremes of weather. When it's cold, it'll be colder, and snowier. When it's hot and dry, it'll be hotter and dryer. Slowly over time, a steady change is bad, and is happening.
We don't panic at the heating/cooling cycle that occurs in one year because we've been through several cycles. But we DO go totally nuts over the 50 year and 200 year solar cycles that have an effect on weather and climate. If there IS a global climate change, that doesn't mean it's Manmade.
It it used to be called global warming. We are entering a miniature Ice Age. Look it up. They had to change it from global warming, because no one would believe in something called global warming. The entire concept of climate change, is that pollutants and stuff create a greenhouse effect, and make the globe hotter. So no, I don't believe in global warming.
First off I do believe in climate change, second this happens without climate changes help, to be a desert it doesn't have to have no precipitation at all it just has to have less than a certain amount of precipitation, so snow on a cold deserts night is kinda normal
Without penguins.
