There are many impacts of a warming environment. Most are already happening, although not all are noticeable yet in your backyard. Take some time to watch/read the following so that we have a common background for some activities in August.

Climate Change, The Cost of Inaction (3:25) US EPA 

Watching Rising Seas from Space (1:58) NASA JPL 

In Climate Change: Evidence, Impacts, and Choices, read Part II: Warming, Climate Changes and Impacts in the 21st Century and Beyond

Also, read about impacts in your region in the National Climate Assessment. (Use the Menu in the upper left to select your region.)

If you have some extra time (or for future reference) Bloomberg put together an article on how changes in the climate may impact food resources.  Check out Climate Change Is Messing with Your Dinner.
