Sea surface warming faster than expected

www.esa.int

Satellite observations show that sea-surface temperatures over the past four decades have been getting warmer at an accelerated pace.

Between 1985 and 1989, a warming of 0.06 C per decade was observed, while from 2019 to 2023, the sea-surface temperature rose by 0.27 C per decade. This suggests that sea surface temperatures are rising 4.5 times faster since 2019 than they were at the end of the 1980s.

The study calculated monthly global mean sea-surface temperature using global satellite data records generated through ESA’s Climate Change Initiative (CCI). The dataset used observations from 20 infrared radiometers on board satellites including ESA’s ERS-1, ERS-2, Envisat, Copernicus Sentinel-3 and two microwave radiometers from 1980 to 2023 to provide a globally accurate temperature trend.
