Future ocean biomass losses may widen socioeconomic equity gaps.

ABSTRACT: Future climate impacts and their consequences are increasingly being explored using multi-model ensembles that average across individual model projections. Here we develop a statistical framework that integrates projections from coupled ecosystem and earth-system models to evaluate significance and uncertainty in marine animal biomass changes over the 21^st century in relation to socioeconomic indicators at national to global scales. Significant biomass changes are projected in 40%-57% of the global ocean, with 68%-84% of these areas exhibiting declining trends under low and high emission scenarios, respectively. Given unabated emissions, maritime nations with poor socioeconomic statuses such as low nutrition, wealth, and ocean health will experience the greatest projected losses
