Impacts on Ecosystems and Organisms

 
 

• Because of climate change, limited habitat is expected to remain in Pennsylvania by the end of the century for northern hardwood tree species including black cherry, sugar maple, and yellow birch [30].

• Phenological changes may lead to mismatches between plants and pollinators and predators and prey with continued warming [31].

• The suitable range of some bird species is shifting. For instance, the range of black-capped chickadees is moving northward at approximately 1 mile per year in Pennsylvania [32].

• Warming temperatures are expected to negatively impact cold water fisheries. By the end of the century, Pennsylvania is projected to be unsuitable for cold water fish species such as brook trout if emissions continue at their current rate [33].
