Climate change is causing a significant decline in suitable habitats for non-targeted fish species in the Mediterranean Sea, according to a new study. Researchers used computer models to predict where these fish would thrive in the future, and found that 97% of the species would face habitat loss, particularly in areas with warmer waters and higher emissions. The study also found that some species are at high risk of extinction, and that the fish are likely to move to new areas as their habitats shrink. The Mediterranean Sea, which is already facing many environmental challenges, is particularly vulnerable to these changes, with some areas showing a high level of species turnover, or loss of biodiversity.
