The Great Lakes Go Dry: How One-Fifth Of The World’s Fresh Water Is Dwindling Away – ThinkProgress
"...Increasingly, scientists believe that climate change is driving the warming waters and setting up a new regime in the Great Lakes that may lead to lower lake levels and a permanently altered shoreline.
Ever since the 1990s, Lake Michigan has been predominantly below its long-term water level average, and trending downwards.
...“The 1998 El Niño gave us a taste of what we can expect to see on the Great Lakes in a changing climate,” said Don Scavia, Co-Director of the Great Lakes Integrated Sciences and Assessments (GLISA).
...In other words, last winter’s record low lake levels are a glimpse of what a warmer climate in the region would do to the lakes — a glimpse that so far has lasted 15 years, set off by one hot summer.
...“The general consensus right now, looking at a broad range of models that have been developed for the Great Lakes, is that there is a big range of variability, but there appears to be a decreasing trend in water levels over the next century,” said Gronewold.
