"Oceanic Transformation: Climate Change Turns Blue Seas Green"

Satellite measurements over the past two decades have revealed that the color of the ocean surface is shifting from blue to green, indicating changes in the ecosystem beneath. Researchers have found that 56% of the global sea surface has undergone a significant change in color, with much of the change stemming from the ocean turning more green. This shift confirms a trend expected under climate change and suggests changes to ecosystems within the global ocean. The color changes are likely due to different assemblages of plankton and a more stratified ocean caused by surface waters absorbing excess heat from climate change. NASA's upcoming PACE satellite will provide finer color resolution data to further study ocean ecology.
