NASA FINDS EARTH'S LAKES ARE WARMING

In the first comprehensive global survey of temperature trends in major lakes ( reported on ScienceDaily )NASA researchers have found that Earth's largest lakes have warmed during the past 25 years in response to climate-change. Satellite data was used to measure the surface temperatures of 167 large lakes, which showed an average warming-rate of 0.45 degrees Celsius per decade, with some lakes warming as much as 1 degree Celsius per decade. The trend was global; the greatest increases were in the mid- to high-latitudes of the Northern Hemisphere.

The results have implications for lake ecosystems, which can be adversely affected by even small water temperature changes.
