The assessment synthesises global and regional evidence across regional and thematic report chapters along a continuum from observed to projected impacts and risks, the spectrum of incremental and transformational adaptation, and finally any evidence on soft and hard limits. We present regional evidence for two types of salient natural and human systems and RKRs: RKR-B , where we assess risks from marine heatwaves to coral reefs; and RKR- E . Both RKRs and systems are facing substantial  risk, characterised by adaptation limits and sharing heatwaves as the hazard, for which climate change has been considered the major driver of increasing intensity and frequency  . The assessment synthesises evidence on transformation as reported in the chapters as well as categorises identified adaptation options
