Changing Planet: Warming Lakes
Satellite observations of lake temperatures at many lakes around the world show that lakes are warming worldwide. These satellite observations are in agreement with measurements taken in many lakes, large and small, which show increasing temperatures and changes in lake ecosystems. Because lakes play such an important role in society, as a source of food, water, and recreation, these changes can have a significant impact on many aspects of our lives. Scientists are just starting to study and understand the implications of rising temperatures on lake ecosystems.Watch the NBC Learn video - Changing Planet: Warming Lakes to find out more.
