Will the Great Lakes rise due to climate change?
Will the Great Lakes rise due to climate change?
The Great Lakes region includes parts of eight states in the U.S. and Ontario in Canada. Great Lakes observers have amassed ample evidence that climate change is causing the lakes’ high water cycles to get higher and low cycles to get lower, and predict that these cycles could happen more rapidly.
How will climate change affect the Great Lakes region?
Areas within the Great Lakes Basin will see an increase of 17 to 40 extremely warm days as annual average temperatures continue to rise. Meanwhile, in states surrounding the Great Lakes, the number of extremely cold days (with temperature less than 32°F) will decrease significantly.
Why are water levels dropping in the Great Lakes?
The drop in water levels could be because of the world’s changing climate and the resulting change in temperatures and precipitation. The amount of evaporation taking place on the lakes has changed, while precipitation has, too.
What is causing the high water levels in the Great Lakes?
Why are the Great Lakes water levels so high? Water levels in the Great Lakes are influenced by precipitation, runoff, and evaporation: The lakes have had record ice cover during several past winters resulting in less water evaporating from the lakes during the winter.
Will Great Lakes water levels continue to rise?
The Great Lakes are in a period of the year when their water levels usually rise. But all of the Great Lakes are not rising or just barely rising. This is a continued sign that for the current time, the Great Lakes water levels are receding quickly from the record high levels over the past few years.
What controls water level in Great Lakes?
The Iroquois Dam, Moses-Saunders Power Dam, Long Sault Dam and the Eisenhower and Snell Navigation Locks contribute to the control of lake levels. The main control structure, Moses- Saunders Powers Dam, has the capacity to discharge 333,000 cfs of water from Lake Ontario in the St. Lawrence River.
Can the Great Lakes water level be controlled?
Controls exist to manage Great Lakes water levels, but the GLC contends that they are not efficiently utilized. The natural factors that affect water levels are precipitation, evaporation, and run off. Structures have been designed and engineered to control the flow of water through the Great Lakes system.
Are the Great Lakes warming?
Climate change impacts All the Great Lakes are warming, but Lake Superior stands out. Still the coldest lake, its summer surface water temperatures increased 2.5 C between 1979 and 2006, even faster than air temperatures. Even the deep waters of Lake Michigan are warming at a rate of 0.5 C per decade.
Are Great lake water levels controlled?
The Great Lakes water levels currently are controlled by several factors, including the Soo Locks, which regulate the outflow from Lake Superior, and five diversions that transfer water in and out of the Great Lakes basin, including the Welland Canal, which connects lakes Erie and Ontario.
