Climate change is quickly warming lakes around the world… threatening freshwater supplies and ecosystems… according to a new NASA and National Science Foundation study published in Geophysical Research Letters and announced yesterday at the American Geophysical Union meeting in San Francisco.
Using more than 25 years of satellite temperature data and ground measurements of lakes on six continents… this study found lakes are warming an average of 0.61 F each decade.
The scientists say this is greater than the warming rate of either the ocean or the atmosphere.
The researchers said various climate factors are associated with the warming trend. In northern climates… lakes are losing their ice cover earlier in the spring and many areas of the world have less cloud cover… exposing their waters more to the sun’s warming rays.
