Since SROCC, coastal adaptation using NbS, like restoration of coastal vegetation, has advanced substantially . Field and modelling studies confirm that wetland restoration and preservation are key actions to restore coastal protection and reduce community vulnerability to flooding  , while maintaining coastal ecosystem services . Restoring coral reefs, oyster reefs and mangroves  and protecting macrophyte meadows dissipates wave energy , accretes sediment and elevate shorelines, which reduces exposure to waves and storm surges, and offsets erosional losses  . However, irreversible regime shifts in ocean ecosystems due to SLR and extreme events, such as MHWs, can limit or compromise restoration in the long term  . Under all warming scenarios, coastal wetlands will be impacted by warming and MHWs , while also being pressed inland by RSLR . Therefore, restoration and conservation are more successful when non-climate drivers are also minimised  .
