Change in the climate of an area or of the whole world over an appreciable period of time.
It is the change in average weather conditions from one period of time (30–50 years) to the next.
Climate fluctuations are natural phenomena, but there is increasing evidence to suggest that human industrial activity affects the global climate, particularly in terms of global warming.

 Global Climate Change
Global climate change is a change in the long-term weather patterns that characterize the regions of the world.
Natural changes in climate usually occur over; that is to say they occur over such long periods of time that they are often not noticed within several human lifetimes.
This gradual nature of the changes in climate enables the plants, animals, and microorganisms on earth to evolve and adapt to the new temperatures, precipitation patterns, etc.

Climate change may also affect diseases spread by snails or by water, such as schistosomiasis and cholera, because changes in rainfall will have an impact on flow of rivers and levels of lakes; melting of polar ice may raise the sea level and inundate coastal and delta regions.
In order to survive global climate change (and some of these infectious agents will not survive) the agents will need to have reservoirs that will survive; they will probably survive by moving in a polar direction, north in the Northern Hemisphere, in order to find a temperature range that is ecologically permissive.
