I am a scientist, and people mistake the issues here constantly. The problem is not that the earth is warming. The problem is that we have too many people; we are dangerously close to the carrying capacity of the Earth, and any change in the temperature, warmer or colder, could be disasterous.
It is true that the earth goes through natural cycles. But just because they are natural, doesn't mean you shouldn't worry about them. This is something to be terribly, terribly worried about; it's far more scary than the prospect of, say, giant meteorite impacts. There is evidence that at points in the past, the entire planet was covered in ice. Think our civilization could survive that?
The earth's climate is a delicate system, and we don't know what controls it. If you don't know how your life-support system works, it's probably a bad idea to start messing with it. Right now, we are dumping huge amounts of CO2 into the atmosphere. We don't know what it will do in the long term. This is a dumb thing to do.
