An article in the New York Times is warning that extremes may be the new norm as Great Lakes water levels are poised to break records again this year. As global warming continues to cause extreme fluctuations in weather and water levels, local governments and lakeside business and property owners must develop a game plan to adapt to and mitigate all the potential impacts. This article lines up with GBA’s position on what to expect this year, and why it is possible that there will be even higher levels in future years. The watchword is “be prepared for extremes” both high and low water levels as climate change effects increase. Read the article here.
