https://www.usatoday.com/story/news//2019/02/28/climate-change-shrinking-fish-population-worldwideFarewell, fish-and-chips? Atlantic cod, many other fish dwindling as globe warmsFish in the Northeast Atlantic – including cod, the prime ingredient in fish-and-chips – saw a dramatic drop of 34 percent in the past several decades as the Earth warmed.
And it's not only cod: many other species of fish are in hot water – literally.
Warming oceans from human-caused climate change has shrunk the populations of many fish species around the world, according to the study released Thursday.
Looking ahead, "future fisheries production may be at even greater risk considering that, owing to (human-caused) climate change, the oceans are continuing to warm even faster than originally predicted," said Australian scientist Éva Plagányi in a commentary that accompanied the study.
Additionally, the study only looked at how warming oceans affect fish and did not take into account other climate-driven impacts, such as ocean acidification, which can also lead to marine populations declines. The world's seas are becoming increasingly acidic because of the rising levels of atmospheric carbon dioxide.
The study was published in the peer-reviewed journal Science.
