Climate Change Impacts on Flood Risk Uncertainty
Climate change drivers affect flooding risk, but the exact relationship between changes in these factors and future flood levels in specific areas remains uncertain, creating multiple potential future flood risk scenarios without clear consensus on likelihood.
The key challenge for flood risk management is that the effect of these drivers (and more specifically changes in these) on the risk of flooding is not certain, with no clear evidence linking changes in these factors to given changes in flooding levels in particular areas. As a result, there are many potential future levels of flood risk that could be realised, with no clear consensus over which levels of flood risk are more likely than others.
