UMD-Duluth researchers say Lake Superior among fastest-warming lakes in world.

DULUTH, MINN. – Researchers at the University of Minnesota-Duluth say Lake Superior is warming due to climate change.

Data from the Large Lakes Observatory shows the lake has warmed about one degree a year since the 1980s, making it one of the fastest-warming lakes in the world.

Researchers say that the warming trend leads to various problems, including large algae blooms spotted on the lake during the summer.

One U-M-D official said in a recent study that if greenhouse gas emissions continue at their current rate, Lake Superior will stop freezing during the winter sometime after 2060.
