Lakes Around The World Are Heating Up

Not surprisingly, measurements show the world's lakes are warming as the climate changes. Interestingly, they are not warming at the same rate. I would expect small ones to warm faster than big ones simply due to thermal dynamics of a large body of water versus a small one. But, that isn't always true. Sometimes, the larger lakes, such as Lake Superior, are warming the fastest. And, some lakes are even cooling.

There was an interesting article (Lakes worldwide feel the heat from climate change, Vol. 191 No. 9, May 13, 2017, p. 18) in Science News about the subject. Here is a graphic showing the trends for 235 lakes worldwide.
