TL;DR: An integrated global ocean assessment of climate change impacts using an ensemble of multiple climate and ecosystem models reveals that global marine animal biomass will decline under all emission scenarios, driven by increasing temperature and decreasing primary production.

TL;DR: The Fish-MIP protocol as mentioned in this paper is designed to allow these heterogeneous models to be forced with common Earth System Model (ESM) CMIP5 outputs under prescribed scenarios for historic (from 1950s) and future (to 2100) time periods; it will be adapted to CMIP6 in future iterations.

TL;DR: In this paper, the authors developed a method that applies generalised additive models to catch-at-length data from trawl surveys and a commercial catch and discard monitoring program in the North Sea to estimate catch-ratios.

TL;DR: A new analytical method that uses carbon (C) and sulphur (S) natural abundance stable isotope data to assess the relative contribution of pelagic and benthic pathways to fish consumer production demonstrates that a substantial proportion of fish biomass in the northern North Sea is supported by production that has passed through transformations on the seabed.

TL;DR: The authors' ensemble projections provide the most comprehensive outlook on potential climate-driven ecological changes in the ocean to date, with good model agreement on the direction of change but variable magnitude.
