Slow and subtle changes in ecosystem composition and distribution are determined by a number of factors such as: seasonal temperatures, precipitation patterns, soil moisture patterns, severity of extreme storm events and natural disturbances, and the abundance of pests and diseases. As these factors change, the habitat required for species may shift. Species you find on your waterfront property today may not be there in the future. Fish populations that are not adapted to the warmer temperatures may begin to disappear while those who prefer warmer temperatures will expand their ranges. Warmer water temperatures provide more favourable conditions for toxic algal blooms which could make water undrinkable and/or un-swimmable.12 Shifting species distribution 12.

In both seasons the potential to shift northwards in a warming climate is significant. While the loon may be able to keep pace with the rapidly changing climate, it looks all but certain that we will lose the iconic loons in summer by the end of the 21st century. 44% of summer 2000 range is stable. 9% increase in summer 2080 from 2000 range. 25% of winter 2000 range is stable. 12% decrease in winter 2080 from 2000 range.
