An international team of researchers reports evidence that a warmer ocean leads to decreases in fish size. In their study, published in the journal Science, the group analyzed a sediment sample from the ocean floor providing evidence of ocean life going back 130,000 years, to a time when the planet was significantly warmer. Moriaki Yasuhara and Curtis Deutsch, with the University of Hong Kong and Princeton University respectively, have published a Perspective piece in the same journal issue outlining the work done by the team.
