Regardless of what we do, it's very likely that the next ice age will start within the next 2,000 years. In the mean time, it makes sense for mankind to continue to advance our technology. Right now, it makes sense to build a lot more nuclear reactors, and develop new energy sources. After all the oil, coal, and natural gas won't last forever.
Below are a couple of informative links. They summarize information collected by geologists and paleontologists. These kinds of scientists have the advantage of looking at hundreds of millions of years of physical history, while our alarmist climatologists are simply extrapolating from insufficient data.
Granted, the past isn't the future, but having a better grasp of what went on in the past can give great perspective about what's likely to occur in the future.

The second of your two links makes WVa look like a paradise; and if we accept that the earth rotates slower when more mass is located at the equator, the current trend would lead one to think that we are slowly but steadily speeding up as the mass moves toward the poles thereby creating the depressed Artic sea levels discussed here earlier.
