Climate change

Attributed directly or indirectly to human activity that alters the composition of the global atmosphere and is in addition to natural climate variability over comparable time periods; often used to describe global warming with environmental implications including temperature and sea-level rises; changes in rainfall and the intensity and frequency of extreme weather events; groundwater, atmospheric, and ocean circulation patterns and locations; and displacement of ecosystems and commercial resources.
