The ability to adapt to current coastal impacts, to cope with future coastal risks and to prevent further acceleration of SLR beyond 2050 depends on immediate mitigation and adaptation actions . The most urgent adaptation challenge is chronic flooding at high tide . Reducing the acceleration of SLR beyond 2050 will only be achieved with fast and profound mitigation of climate change . Until 2050, adaptation planning and implementation needs are projected to increase significantly in most inhabited coastal regions . For SSP1-2.6 and more strongly forced scenarios, SLR rates continue to increase , and so do the scale and frequency of adaptation interventions needed in coastal zones .
