Even though movies like The Day After Tomorrow scare us about a pending ice age that can strike in weeks, the scientist believe it will not happen for at least another 1,500 years and should take two to three years to set in.  Learn more in the Next ice age not likely before 1,500 years: study at Reuters.

The big question is: how can global warming cause an ice age?  It does not make sense – heat does not cause cold.  But, the complexity of earth’s environment provides a way for it to happen.  The theory is that global warming will melt Arctic ice and the resulting fresh water will disrupt the ocean’s Gulf Stream, which warms the northern Atlantic.  Find out more at How Global Warming May Cause the Next Ice Age at Common Dreams.
