Georgian Bayers may have dodged a bullet for now. Ice cover, a significant determinant of lake levels (as well as summer water temperatures and spring plankton blooms) should reach 57-62% across the Great Lakes by February say GLERL scientists (Great Lakes Environmental Research Laboratories.) This is slightly above the long-term average. Last year ice cover came in at 38.4%.
The U.S. Army Corps of Engineers predicts all the Great Lakes except Huron-Michigan will reach their average water levels or exceed them this summer, but a wide swath of uncertainty still remains.
The turn around poses special problems for shoreline communities. They’re now up against the reality that water levels go up as well as down and this can happen fast. (Of course fluctuations are a given, we know this, but much of the lobbying for doing something about low water levels has focused on low and lower water levels.)
Sadly, the upswing this year, doesn’t change the fundamentals of climate change; the Great Lakes are evaporating at a greater rate than we would like.
Shoreline communities around the world are the hardest hit as people and critters have always chosen homesteading on the edges of waterways. Entire mini societies and species face complete annihilation. That is not true of communities on the Great Lakes, but a radically refashioned shoreline is pitting nature against us for prime and shifting real estate.
The up-and-downness of it all poses serious dilemmas for higher levels of government considering bailouts for these communities. What’s normal? Are 100-year storms going to show up every couple of years? Given the extent of climate change, who should be compensated and who should fend for themselves? It will take the wisdom of Solomon to thread our way through short-term thinking and dodge the loudest screamers and false prophets to figure out where to slap down our billions. (I’m hoping the long-anticipated Council of Great Lakes Region’s economic study will throw some light on this.)
And don’t think for a second that the restoration of water levels/St. Clair River project that the International Joint Commission recommended to the Canadian and U.S. governments will address the fallout from climate change. It is meant to compensate for what drained away via dredging in the ’60s.
In an excellent report by UNESCO on learning to live with climate change, the authors warned against such boutique projects. “Avoid skewing financing to specialty projects that might be easily labeled adaptation but do not necessarily maximize net benefits.” Let’s hope the federal governments who are expected to come up with a response to the recommendations of the International Joint Commission keep their sights firmly on climate change.
The big questions are, what is the quality of our environment, our economy, our water supply, and how can we fix what’s ailing. Through the prism of adapting to climate change, we can address questions we should have asked ages ago, infrastructure questions as well as local questions such as, is it possible for a dock to coexist with an encroaching wetland—seeing as the old wetland is now a meadow?
Governments and think tanks are jumping into adaptive management but their attempts seem soporifically bureaucratic. It’s still early days. Success will depend on innovation and big thinking, but just as importantly it will come from ordinary folks figuring out how to run their lives and businesses in a testier world. This could be a job creator. Yes we badly need engineers and lots of money, but also small, incremental, artisanal, locally made solutions, and millions of cut-and-paste proposals.
