The National Oceanic and Atmospheric Administration (NOAA) revealed water hundreds of feet below the surface of Lake Michigan is warming. Experts have long known that Lake Michigan temperatures are rising and ice cover is dwindling as a result of human activity. Researchers have been investigating Lake Michigan since 1990, using a string of thermometers floating vertically in southern Lake Michigan to gather measurements.

Lakes can serve as 'climate change sentinels,' the study says, and deep water measurements can be particularly important because they provide a 'climate memory.'
