Risk is defined here as the combination of the likelihood of an occurrence of an event and the severity of the impact that can be caused by the event.

In detail

Understanding the risks and thresholds, including uncertainties, associated with climate change is one principle of good adaptation.

Previous UK climate projections allowed climatic impacts to be identified and quantified, but they provided limited information about the likelihood of their occurrence.

In part as a response to this, UKCP09 provides probabilistic projections. The shape of the probabilistic distributions provides more detailed information about the relative likelihood of different amounts of projected change. You can use Probabilistic climate projection to develop formal risk assessments.
