The Ups & Downs of the Great Lakes

Guest: Mark Torregrossa

Introduction:

    The Great Lakes account for 84% of North America’s surface freshwater, and millions of people across the region depend on these Lakes for water supplies, industry, travel, and recreation.  In recent years, these Lakes have seen a wide range of extremes from record high water levels to sudden, sharp declines, and it has been concerning local residents and officials.  Mark Terragrossa serves as the Chief Meteorologist for MLive.com in Michigan, and he’s been closely following the water levels in recent years.  We’ll discuss what factors may be at play here and how these changes could impact local communities and ecosystems.
