How fast is the ice melting?

A new study from the University of Colorado at Boulder found that glaciers and ice caps are currently melting at a rate of 100 cubic miles a year. That's a volume nearly equal to that of Lake Erie. And the rate is increasing by three cubic miles per year.

The study estimates that this accelerated melting could raise sea levels an additional 4 to 9.5 inches globally by 2100 - not including the thermal expansion of warming ocean water, which could double those numbers. A 1-foot rise in sea level typically causes a shoreline retreat of 100 feet or more.

Is this what Bush means by "We're making progress"?
