This document is a summary of the fourth issue of the Copernicus Marine Ocean State Report and highlights the current state, natural variations, and ongoing changes in the global ocean. It draws on the Copernicus Marine Ocean Monitoring Indicator (OMI) framework. It approaches the topic from several angles, presenting the state of key ocean variables, examining ongoing changes to the ocean in line with climate change, analysing natural variability and extreme events, and discussing the services that the ocean provides to humanity. Finally, new tools and success stories from the Copernicus Marine Service illustrate how accurate, timely information is key to understanding and adapting to the evolving ocean and seas. |
