If the tuna that Pacific Island communities have reliably fished for generations were to change their behavior — migrating to different areas of the ocean or in smaller numbers, for example — it could upend the marine food chain and the livelihoods of fishers across the Pacific.

A groundbreaking conference in Australia in February 2016 painted a fuller picture of mass species migration in response to climate change — and what it means for human well-being. The conference’s findings were published recently in a global review in Science.

Find out what could happen to species migrations if the patterns of climate change continue in the original post.
