  13. 13. Date Name of Meeting 13 Certain Types of Extreme Events Show Important Trends – Heat waves are generally increasing; will likely become longer and more severe. – Cold waves are decreasing. – More precipitation coming as larger events. – Increasing risk of floods in some regions (NE, MW). – Droughts increasing in some regions (SW, SE). – Increasing intensity of Atlantic hurricanes is likely. These trends are likely to continue.

  26. 26. Date Name of Meeting 26 The Great Lakes Climate change will exacerbate a range of risks to the Great Lakes, including changes in the range and distribution of certain fish species, increased invasive species and harmful blooms of algae, and declining beach health. Ice cover declines will lengthen the commercial navigation season.
