Uncertainty can result from lack of information or from divergent opinions about what is or can be known. [3]

There may be many causes of uncertainty: faulty data, ambiguous concepts and terminology, or uncertainty about how people will behave. Uncertainty may be expressed in figures – for example where different climate models arrive at different forecasts about the rise in temperature. however, uncertainty may also be a qualitative statement by a team of experts.
