By Phil McKenna Climate policies that rely on decarbonization alone are not enough to hold atmospheric warming below 2 degrees Celsius and, rather than curbing climate change, would fuel additional warming in the near term, a study published Monday in the Proceedings of the National Academy of Sciences concludes.
