ken: Maybe, maybe not. The planet naturally goes through warming and cooling cycles. We really don't know the extent to which human activity effects it.

Given that, I think we should take prudent steps to minimize our footprint. We shouldn't go overboard, though.

Uh, James, we do know why ice melts. Just turn the thermostat in your freezer to somewhere above 32 degrees and watch the ice melt. Scientists have been aware of the effect greenhouse gases have on our plantet for over a century. But it was the introduction of man made greenhouse gases that led to them predicting the melting of the ice caps. So far the scientists have been proved right.
