Projected Changes in Great Lakes Levels under Higher Emissions Scenario

Projected Changes in Great Lakes Levels under Higher Emissions Scenario

Average Great Lakes levels depend on the balance between precipitation (and corresponding runoff) in the Great Lakes Basin on one hand, and evaporation and outflow on the other. As a result, lower emissions scenarios1 with less warming show less reduction in lake levels than higher emissions scenarios.1 Projected changes in lake levels are based on simulations by the NOAA Great Lakes model for projected climate changes under a higher emissions scenario.1  Image Reference: Hayhoe et al.2
