Marine heatwave: UK sea temperatures soar after exceptionally warm Spring

Marine heatwave: UK sea temperatures soar after exceptionally warm Spring

Georgina Rannard, a climate and science reporter, brings attention to the rising sea temperatures in the UK and Ireland over the past week. These elevated temperatures are now 4 degrees Celsius warmer than usual, raising concerns for marine life and people engaging in swimming activities. Notably, the most significant impact of this heatwave is observed off the west coast of Ireland and certain areas near Cornwall and Devon, as reported by experts from the National Oceanography Centre and the Met Office.

In April and the first half of May, sea temperatures reached record highs, marking the warmest temperatures during these months in the last 45 years of monitoring. The escalation of marine heatwaves, such as the current situation, is linked to climate change, which is causing oceans to warm globally. With the upcoming predictions for 2025 suggesting it to be one of the hottest years on record for air temperatures, the urgency to address these environmental shifts is pressing.

Dr. Ségolène Berthou of the Met Office remarks on the intensity of the current marine heatwave, while Dr. Zoe Jacobs from the National Oceanography Centre notes its inception in the North Sea and Celtic Sea during the winter and spring. The surge in temperatures has persisted longer than expected, with the west coast of Ireland experiencing particularly high temperatures. These sustained heatwaves are expected to increase in frequency and strength, potentially disrupting marine life and ecosystems in unpredictable ways.

While scientists are still unraveling the full extent of the impacts, signs suggest that the marine heatwave might disrupt breeding patterns of species and attract jellyfish blooms in the warmer waters. The influx of warm-water fish like bluefin tuna into UK waters could also result from these elevated sea temperatures. As research and observations continue to unfold, it becomes evident that urgent action is needed to mitigate the long-term consequences of these changes on marine habitats and coastal communities
