Caribbean sardine collapse linked to climate change

The collapse of sardine fisheries in the southern Caribbean Sea during the past decade may have been driven by global climate change, according to a study in which researchers from the United States and Venezuela linked ecological measurements in the southern Caribbean Sea with global climate change indicators.
These indices were revealed to correlate to changes in regional wind and seawater circulation patterns, which may have dire socioeconomic consequences for Caribbean countries — such as the collapse of valuable sardine fisheries. The conclusions are based on monthly measurements taken over a period of 14 years in the Cariaco Basin, off the northern coast of Venezuela. They were published in Proceedings of the National Academies of Science (PNAS), last month (15 October).
