Climate change affects agricultural productivity. New systematic global agricultural yield projections of the major crops were conducted using ensembles of the latest generation of crop and climate models. Substantial shifts in global crop productivity due to climate change will occur within the next 20 years—several decades sooner than previous projections—highlighting the need for targeted food system adaptation and risk management in the coming decades.

In wildlife tagging, stress from capture and handling can alter post- release behavior and potentially study interpretations. This study of 42 mammal species shows that these effects diminish within 4–7 days, and quicker for animals in high human activity areas indicating adaptation to disturbance.

The genetic diversity of wild relatives of domesticated crops can be useful for developing more productive, nutritious and resilient crop varieties. A comparison of the modelled diversity of crop wild relatives with their representation in gene banks suggests that a systematic effort is needed to improve their conservation and availability for use in plant breeding.

This study shows that photosynthesis in the Arctic Ocean can occur at lower light levels than previously thought. This finding is based on unique measurements made on microalgae underneath sea ice in the high Arctic at the end of the polar night.

Responses of agriculture and fisheries to climate change are interlinked, yet rarely studied together. Here, the authors analyse more than 3000 households from 5 tropical countries and forecast mid-century climate change impacts, finding that communities with higher fishery dependence and lower socioeconomic status communities face greater losses.
