Climate Change Messes With Fish

Climate change is leading to bigger fish in shallow water. But it's also making littler fish in deeper water, reports The Mercury, in Hobart, Tasmania. The study involved scientists examining 555 fish earbones aged two to 128 years, which show similar characteristics to tree-growth rings. These data were correlated with water temperature records taken over 60 years from the waters around Tasmania. The findings prove that water temperature has been a primary factor in determining juvenile growth rates in the species examined. --Julia Whitty
