The data gathered so far from modern/pre modern temperature records seems to be supporting this prediction of the GWT's, and thats not something even the deniers can hide from. Its happening now.

I doubt that there is any "serious" loss of ice at the poles. Certainly for the Antartica, there is no evidence of ice loss. In fact sea ice last winter was at it greatest extend.
This can be seen in the temperature records here:

We are a hardy species!

Our civilisation has much to fear from a new ice age. Glaciers covering northern Europe and North America would be devastating.
In contrast, a few degrees rise in termperatures will have a minor effect, despite what some would like you to believe.
