解释：

Physical and transition risks are often assessed separately but may need to be considered jointly due to the interdependence of certain climate-related hazards. Physical risks can be assessed using damage functions and transition risks can be estimated using models linking transition risk drivers to economic factors. Physical and transition risks cannot be assessed using the same methodology or that policymakers are unlikely to take decisive actions to mitigate physical risk impacts in the future.
