The fact is, the planet is warming. That's very true. It's done this before, but it's doing it again, only more quickly than in previous cases. What's also clear and true is that the pollution cars emit doesn't help with the situation either; it makes it worse. CFC emissions are also damaging to the ozone, contributing to the situation.
What's also clear and true is that the planet goes through natural cycles of these things. Why? I really don't know. It just does. Whatever the reason, the one thing we can be sure of is that man is partially to blame as is the environment. People outright denying its existence entirely, though, really don't know what they're talking about. It exists, but it's not totally man's fault and it's not totally the environment's fault. It's both.
