Increases in Great Lake winds and extreme events facilitate interbasin coupling and reduce water quality in Lake Erie

Abstract Climate change affects physical and biogeochemical processes in lakes. We show significant increases in surface-water temperature (~ 0.5 °C decade−1; > 0.2% year−1) and wave power (> 1% year−1; the transport of energy by waves) associated with atmospheric phenomena (Atlantic Multideca...
