PASADENA, Calif.—Water temperature in major lakes around the world have been steadily increasing over the past 25 years as a result of global climate change, according to a study released today by researchers at NASA's Jet Propulsion Laboratory in Pasadena.
According to the study, the Earth's major lakes have warmed by an average of 0.81 degrees per decade, with some warming as much as 1.8 degrees.
Although the warming trend is global, the greatest increases are in the mid-to high-latitudes of the Northern Hemisphere, the study found.
