This is the third and final installment of a three-part series on climate change. Slight changes in climate may cause abrupt changes in ecosystems that are not easily reversible. Some of these responses, including insect outbreaks, wildfire, and forest dieback, may adversely affect people as well as ecosystems and their plants and animals. USGS scientist Colleen Charles discusses a new report on the impacts of a warming world on ecosystems.
