Climate Change’s Potential Effects on Lake Ontario and Saint Lawrence River, Canada and USA43.6N 78.1W
Snow dusts the landscape of part of the northeastern USA and Canada, framing the shores of the Saint Lawrence River. The river traverses the Canadian provinces of Quebec and Ontario and forms part of the international boundary between Ontario and New York in the United States. It is the primary drainage conveyor of the Great Lakes Basin, and in this image can be seen connected to Lake Ontario.
In the opinion of some experts, a temperature increase of 2 to 4°C could lower the average flow from Lake Ontario by 24%. Lake Ontario is the major source for the St. Lawrence River, and a decrease in flow of this magnitude could result in a 1-metre drop in water levels in some areas of the St. Lawrence.
