A new study published in Nature Communications reveals that marine heatwaves significantly impact microscopic organisms in the ocean, altering food webs and the ecosystem's ability to combat climate change. These prolonged warming events are becoming more frequent, with record sea temperatures observed in places like Portugal and the Mediterranean. The research, focusing on the Gulf of Alaska, shows that heatwaves disrupt phytoplankton and the ocean's carbon cycle, increasing the risk of carbon returning to the atmosphere. The study highlights the need for enhanced ocean monitoring to understand these effects on ecosystems and climate. Teljes cikk (Euronews.com)
