Description:"This report provides background on earlier Great Lakes climate change impact studies, describes the Great Lakes and their climate, presents hydrological models used in assessing climate change, and summarizes results. Detailed time series of net basin supplies to all of the Great Lakes are available for an unchanged climate scenario and four GCM-generated changed-climate scenarios. The higher air temperatures under the changed-climate scenarios lead to higher over-land evapotranspiration and lower runoff to the lakes with earlier runoff peaks since snow pack is reduced and the snow season is greatly reduced. This also results in a reduction in available soil moisture. Water temperatures increase and peak earlier; heat resident in the deep lakes increases throughout the year. Mixing of the water column diminishes, as most of the lakes become mostly monomictic, and lake evaporation increases. Ice formation is greatly reduced over winter on the deep Great Lakes, and lake evaporation increases; average net supplies drop most where precipitation increases are modest"--from Abstract.
