研究显示新西兰周边海洋热浪加剧

Core Viewpoint - New Zealand's surrounding marine waters are experiencing rising temperatures and increasing frequency of marine heatwaves, which may significantly impact fisheries and marine ecosystems [1] Summary by Relevant Categories Temperature Changes - From 1982 to 2022, the surface sea temperature in New Zealand's nearby waters has increased by 0.2 to 0.3 degrees Celsius every decade, while the bottom temperature has risen by approximately 0.1 degrees Celsius per decade [1] Marine Heatwaves - Marine heatwaves, defined as abnormal sea temperature increases lasting five days or more, have become more frequent and intense in recent years [1] - Under high greenhouse gas emission scenarios, the intensity of marine heatwaves is expected to potentially double by the end of this century [1] Impact on Fisheries and Ecosystems - The research indicates that while areas most affected by heatwaves have been identified, more data is needed to better predict the specific responses of ecosystems and potential risks [1] - The findings can assist New Zealand's fisheries and related sectors in adapting to climate change [1]
