The world’s oceans are warming at an alarming rate, with 2023 marking a critical milestone. For the first time, global ocean temperatures surpassed 1\u00b0C above pre-industrial levels, triggering marine heatwave events across both hemispheres.<\/h2>\n
These extreme temperature spikes were seen from Japan and South America to the North Atlantic. As the climate crisis worsens, marine heatwaves are becoming more frequent and intense, posing a serious threat to marine ecosystems, economies, and coastal communities worldwide.<\/p>\n
What are marine heatwaves?<\/h3>\n
Marine heatwaves are periods of unusually high sea surface temperatures lasting at least five days. These heat events can vary in size from localised hotspots to vast stretches of ocean basins.<\/p>\n
While many last for weeks, some have persisted for months or even years in extreme cases. These prolonged temperature spikes disrupt marine environments, often leading to catastrophic consequences for marine biodiversity and coastal industries.<\/p>\n
Global impact on ecosystems and economies<\/h3>\n
The impact of marine heatwaves extends far beyond the ocean. In tropical regions, coral reefs\u2014critical to marine life and coastal economies\u2014have experienced widespread bleaching.<\/p>\n
This coral loss significantly harms tourism. Additionally, many fisheries around the world have been devastated, with mass fish die-offs or migrations disrupting local economies and food supplies.<\/p>\n
