URL of this page: http://www.nlm.nih.gov/medlineplus/climatechange.html

Weather can be hot or cold, dry or wet, calm or stormy, clear or cloudy. Climate is the average weather in a place over a long period of time. Changes in climate may be due to natural forces or from human activities. Today climate changes are happening at an increasingly rapid rate.

Climate change is altering weather and climate patterns that previously have been relatively stable. Climate experts think that climate change will bring increasingly frequent and severe heat waves and extreme weather events, as well as a rise in sea levels. These changes have the potential to affect human health in direct and indirect ways.
