Skeptics can be skeptical of their own skepticism

“Melting of glaciers cause rising sea levels?” (Letters, Feb. 15/16) points to the fact that water contracts as it goes from frozen to liquid. If the writer really wants a fitting experiment, he’ll fill a large glass with all the ice it can hold. Then he pours water into the glass until it reaches half full (or even 3/4 full). Then he sets the glass in room temperature. He’ll see the liquid water level rise as the ice melts.

Skeptics sometimes need to be skeptical of their own skepticism.
