The adaptive capacity of ecosystems and human systems is expected to encounter hard limits due to the interacting, cumulative and cascading effects of droughts, heat waves, sea level rise, ocean warming and acidification . Coastal protection can reduce risks from sea level rise in some regions, but the costs of such interventions and their consequences for coastal ecosystems are high .  There is low confidence in the feasibility of adaptation options to sea level rise beyond 2100 or for large Antarctic ice melting.
