A study with erroneous claims about the impacts of global warming has finally been corrected

A journal article claiming that moderate amounts of global warming have overall positive benefits has been quietly corrected after Bob Ward pointed out a number of errors. The updated analysis now claims “impacts are always negative”, but the erroneous findings have been used to inform a recent report by the IPCC which still needs to be corrected. This episode underlines the need for greater transparency at academic journals and by researchers.
