Sue Long posted a letter (May 3 Reader’s Write) asking readers to conduct their own experiment that "refutes" the "false premise" of the "theory" that melting glaciers, as a result of man-made global warming, will cause sea levels to rise. By placing ice in a glass and filling it with water, we are to correctly observe that the water level does not rise as the ice melts.

A more correct experiment would be to fill a glass with water and then add more water from a nearby bowl of melted ice to see if the level in the glass rises. Of course it does. This observation is not a "theory" or conspiracy symptomatic of "radical green environm...
