Great Lakes fishery managers and stakeholders have little information regarding how climate change could affect the management of recreationally and commercially important fisheries, which have been valued at more than $7 billion annually. Our research has focused on how climate change could influence fish habitat (including water temperature, ice cover, and water levels), phytoplankton production, and ultimately fish production. Focusing on lakes Michigan and Huron, this webinar provids information about: whether we can detect climate signals in long-term data on fisheries and phytoplankton preliminary climate (e.g., water temperature, ice cover) forecasts for 2043-2065 how future climate could influence growth...

Projections of regional climate, net basin supply (NBS), and water levels are developed for the mid- and late twenty-first century across the Laurentian Great Lakes basin. Two state-of-the-art global climate models (GCMs) are dynamically downscaled using a regional climate model (RCM) interactively coupled to a one-dimensional lake model, and then a hydrologic routing model is forced with time series of perturbed NBS. The dynamical downscaling and coupling with a lake model to represent the Great Lakes create added value beyond the parent GCM in terms of simulated seasonal cycles of temperature, precipitation, and surface fluxes. However, limitations related to this rudimentary treatment of the Great Lakes result...
