Overall, most key risks and their severity and extent are strongly driven and determined by system exposure, vulnerability and adaptive capacity. In particular, the high vulnerability of large populations, infrastructure and service systems, such as health, food and energy production and supply, are important factors, along with high levels of inequality and poor governance, for creating and increasing key risks . Prevailing low levels of available information and understanding exacerbate the uncertainties surrounding key risks and so pose limitations to adaptation. An example is CA, with its high levels of vulnerability and exposure, but there is limited evidence and understanding on impacts and risks, making this region susceptible to inappropriate adaptation to expected future climate-change impacts.
