From NOAA GLERL:
Water level extremes and climate change
Based on the General Circulation Model, climatologists have determined that the climate of the Great Lakes basin will increase by 2 to 4 degrees Celsius. Warmer air temperatures affect lake levels by reducing runoff and increasing evaporation from the lake surface. Commercial navigation, recreational boating, and hydropower are impacted by extremes in water levels. In 1997-1998 El Nino was responsible for causing drastic changes in lake levels because of the low snow cover. Studies have shown that the predicted increase in temperature will drop lake levels by half a meter to two meters (Government of Canada / U.S. EPA Great Lakes Atlas).But that was then. This is now. Waters in the Great Lakes have risen.
And via the Weather Channel, this is how the agency spins the data:
“The levels of the Great Lakes go up and down all the time, that’s a given,” Anne Clites, a scientist with the National Oceanic and Atmospheric Adminitration’s Great Lakes Environmental Research Laboratory, told weather.com. “They go up for a few years, they go down for a few years. They have not, in the 155 years we have records for, stayed that far below their long-term mean. That was kind of an unusual event. That’s why we’d like to look at more about what’s causing it.”They said climate change would dry up the lakes. When it didn't, they changed their story.
Why do we employ these liars? Disband the agency. Obviously it is staffed with anti-scientific liars who bend data to fit a political agenda
