- Climate change is rapidly affecting the marine ecosystem. Fisheries are seeing the impact of rapid warming, marine heat waves, and extreme events. Changing water temperatures impacts fish distribution with warm water species appearing in what were more temperate waters. More frequent storms reduce the time that fishers can spend at sea.
Stakeholders want to know not only how climate change will impact their industry but how they can adapt. How can fishers and scientists work together to adapt to future challenges?

How can ICES provide credible climate-informed advice?

The Great Barrier Reef's coral cover reached the greatest extent ever recorded in 2022, 2023 and 2024 (AIMS) despite reports of supposed repeated bleaching. If you look at the Global Coral Reef Monitoring Network (GCRMN) data, the WIO (West Indian Ocean) shows 26% hard coral cover in 1985 upto 30% in 2020. South Asia reefs shows a decline around 2000 to below 25% then a regrowth to around 40% (2010) and a decline to 25% (2020). The Red Sea shows no change at around 25% (1995-2020). So the pattern in these three areas show no relationship to each other or to a changing climate. The Caribbean region reefs have a cover of around 0.15 ± 0.02. There is no evidence of a major reduction in coral cover in the Caribbean over the last two decades.
GCRMN data for the most important coral bioregion, the East Asia Seas, with 30% of the world’s coral reefs, and containing the most diverse coral of the ‘Coral Triangle’, show no statistically significant net coral loss since records began. The East Asia region has the biggest human population living in close proximity to reefs, and is located in the Indo-Pacific Warm Pool - the hottest major water mass on earth.
Life is most diverse in the warmest parts of the world’s oceans. This has been shown across 13 major taxonomic groups from zooplankton to marine mammals. Warmer water = more biodiversity. This is a scare story about things you cannot see.
We can but won't protect our 'resources'.
