Red Sea is Warming Faster Than Global Average

“The global rate of ocean warming has many consequences for life on this planet. Now we are learning that the Red Sea is warming even faster than the global average,” says KAUST PhD student of marine science, Veronica Chaidez.

“The global rate of ocean warming has many consequences for life on this planet. Now we are learning that the Red Sea is warming even faster than the global average,” says KAUST PhD student of marine science, Veronica Chaidez.

The analyses, conducted by a multidisciplinary team spanning all three divisions at KAUST, provide vital data that could help predict the future of the Red Sea’s marine biodiversity when supplemented by evidence to be gathered on the thermal limits of local organisms.

Analyses of satellite sensing data from 1982 to 2015 show that the Red Sea’s maximum surface temperatures have increased at a rate of 0.17 ± 0.07°C per decade, exceeding the global ocean warming rate of 0.11°C per decade. Maximum sea-surface temperatures were found to increase from north to south along the Red Sea basin, with the coolest temperatures located in the gulfs of Suez and Aqaba in the far North. These two gulfs, however, are showing the highest rates of change compared to the rest of the basin at 0.40–0.45°C per decade; four times faster than the mean global ocean warming rate. 

The Northern Red Sea experiences maximum temperatures throughout July, while the Southern Red Sea is warmest from late July to mid-August. Interestingly, sea-surface temperatures reached their maximum in an area on the Eastern coast of the Red Sea, about 200km south of Jeddah, from mid-August to early September. This anomaly may be caused by the unique wind patterns in this region.
