Oceans darkened 21% globally since 2003, study shows

A recent study reveals that over 20% of the global ocean has darkened in the last two decades, potentially impacting marine life and ecosystems. The University of Plymouth research indicates that 21% of the world's oceans have experienced reduced sunlight penetration, a phenomenon termed "ocean darkening," between 2003 and 2022. This is attributed to factors like shifting algal blooms and sea surface temperatures. Scientists are concerned about the implications of these changes, as they could affect marine species and ecosystem services, including the air we breathe and the ocean's ability to combat climate change.
