First of all, I think that global warming is climate change in that the climate is simply changing to a state where the planet is warmer on average.

I think your real question should be is the apparent warming trend that we are viewing a part of a natural cycle that the climate goes through over the eons or is this a deviation from the norm that is the result of our increasing use of carbon fuels?

Personally, I think that this is a natural and not a man-made change. The world is becoming warmer just as it did after the last ice age. If I remember my science correctly there was more than one ice age and back in the age of the dinosaurs the world was warmer than it is now. So I think that what we are observing now is a natural change in the climate cycle. Also, given that there have been major changes such as the ice age and minor changes such as the cooling cycle that began about 1,000 years, this could be no more than the climate warming back up to what it was 1,000 years ago when the French used to import wine from the British rather than vice versa.
