Now all I hear about is how we are headed for another 100,000 year Ice Age. So which is it? Ice Age or GW?

Its hard to tell, we know that the Earth has been much much warmer before and that Carbon levels were 2-4times hiogher before because of natural causes. They can discern this by fossil records, since Ice Cores and anything else used for scientific measurement can only go back about 650,000 years, which is about (.25%) of 25% of the Earths existence.
