Last week, #CopernicusMarine attended #BrusselsClimateWeek, joining a side event to explore how the #OSR10 report reveals a changing #Ocean and #Climate.

The session, hosted by The Parliament Magazine, also explored how the report can bridge the gap between ocean observation and decision-making.
A panel of four individuals is seated on a stage during a fireside chat named "A decade of Copernicus Ocean State Reports: What the ocean is telling us about a changing climate." The setting includes a large screen displaying the event title and the Copernicus Marine Service logo. The panelists are engaged in a discussion.

A colorful infographic titled "Extreme Events in European Seas" shows various events in 2023-2024, using icons and arrows. In February 2024, storms in two Spanish ports cause high waves. Early spring 2024 sees a chlorophyll surge in the Northern Adriatic Sea, plus marine heatwaves in the Mediterranean and Black Seas, leading to record temperatures. Storms from 2023 to 2024 cause salinity drops in the Northern Adriatic Sea. In November 2024, a storm drops the Bothnian Bay to a record-low sea level.
