Does global warming exist?

In my opinion global warming is a big crock. Sure there is a certain amount of truth to green house gasses adding to the effect but honestly I feel that the Earth has always been warming up and that will continue to occur. There are natural cooling and heating cycles that the Earth has gone through and it will continue to go through. Well that's just what I think. How do you feel?

I have to disagree, global warming does exist and we need to do something about it whilst it's just starting to affect the the earth. Just do little things like saving electricity. You save money and help save the environment.

Global Warming is happening; and no one truly knows what will happen, maybe its too late to turn back. Are we all going to die?

Yes my friend there are natural warming and cooling process on the planet similar to day-night process, but it's also true that the Global Warming is happening that too on a huge scale.
As per normal temperature change cycle the global temperature changes approximately .1 degree C in a millenium, but we have witnessed the change of nearly 3-5 degree C in past one century... That's how global warming is effecting the planet's natural temperature cycle.

Around 1998 the world heated up about 1 degree C. In the past few years the world has cooled down to the point where it is back at levels before 1998. They used to rant about global cooling several decades ago. I will have to say....fraud.
