and other economic analyses that incorporate damage estimates are expanding for adaptation decision making , especially for technical options in areas with high exposure such as coastal areas in Mexico  and Alaskan infrastructure . Cost-benefit analysis has also been applied to coordinating planning across jurisdictions in North America for SLR and flood control . Adaptation costs in the USA are lower on RCP4.5 compared with RCP8.5 emission pathways . Adaptation, however, cannot be based solely on the cost-benefit analysis due to the high level of uncertainty related to climate risks .
