Applauds experiment, but points out not germane

A letter concerning melting glaciers (Feb. 15/16) described a scientific experiment related to melting icebergs and sea level rise. I was heartened to see the author using science. Unfortunately, he chose an iceberg experiment, not a glacier experiment. It’s true that icebergs, which are already in the ocean, do not raise sea level because they are not adding water. Glaciers, however, are on land and, like a water faucet, add water to the ocean when they melt. Adding water to the ocean raises sea level. Opening a melting land glacier water faucet over your full ice water pitcher will definitely cause your pitcher to overflow. Nice experiment, but not germane to glaciers.
