On 12 December 2015 the signatory countries to the United Nations Framework Convention on Climate Change (UNFCCC) reached a historic agreement. Five years on from the Paris Agreement the progress and prospects are not equal to the signatories ambitions. The Ocean and Climate Platform (OCP), speaking for some 100 member organizations dedicated to the sea from across the world, is raising awareness of the urgent need to drastically reduce greenhouse gas emissions and reinforce efforts to adapt coastal regions to the rising sea level. Of particular concern are coastal cities that are experiencing considerable population growth. The human and economic impacts expected in the short term are colossal. In addition to the vital goal of attaining carbon neutrality, we are facing a new race against time which requires the reinforcing of adaptation measures at COP26.
