I tend to agree. Global warming is the culprit only if it means we will consistently get much higher rainfall in the Great Lakes area than we have normally gotten. 

One year (this year) is much too short a time frame to determine if "the climate" has changed to being much wetter. 

Maybe standing on the shore of Lake Ontario, politicians are inclined to think of it as an 'ocean' rather than a 'lake' ?? ;)
