Ocean Warming to Shrink Marine Mollusks by 2100

A study led by Isaac Trindade-Santos and Craig McClain projects that ocean warming could cause most marine mollusks to reduce their body size by 2100. The research, published in the Proceedings of the National Academy of Sciences, analyzed over 23,000 species in different ocean basins and projected changes under high and low greenhouse gas emission scenarios. The study challenges the widely held idea that ocean warming would simply reduce marine life. It found that some groups could shrink significantly, while others could experience size increases in certain areas, depending on the biology of each group and the conditions of each marine region.
