Ocean productivity has been declining globally for the past three decades, with repercussions for fisheries, marine biodiversity, and the planet’s climate regulation systems.

Ocean productivity refers to how much food and energy the ocean produces to support marine life.

According to a new study led by the Council for Scientific and Industrial Research (CSIR), analysing 26 years of satellite data, climate models underestimate the global decline in the productivity of the oceans resulting from ocean warming.
