WCRP Climate and Ocean Variability, Predictability and Change (CLIVAR)  is excited to announce the publication of a new paper "A Global Overview of Marine Heatwaves in a Changing Climate" by the Marine Heatwaves in the Global Ocean Research Foci Group. This comprehensive article provides a review of advances in understanding marine heatwaves (MHWs) and their increasing impacts on marine ecosystems worldwide. Marine heatwaves have become a major concern due to their profound effects on ocean ecosystems, fisheries, and coastal communities. The paper explores the three-dimensional structure and evolution of these extremes, their drivers, their connection with other extremes in the ocean and over land, future projections, and assessment of their predictability and current prediction skill.

The paper, published in Communications Earth & Environment, is available here.
