while I appreciate the links, and undoubtable the information is relevent to the recording ability of local stations, it remains undeniable that the actual melt-rate of glaciers and arctic ice is much higher than during previous generations. whether or not you believe this is a result of humans or natural changes, the fact remains that a) sea levels are rising slowly over the next couple decades, and b) humans tossing more catalyst into the atmosphere isn't going to help that any.

bluntly, scientists don't like uncontrolled experiments, and the things humans do to the environment without a clue as to results are shortsighted and ill-planned.
