Old simulations still have uses.  A new study titled “Are estimates of anthropogenic and natural influences on Australia’s extreme 2010-2012 rainfall model-dependent?” has just been published in the journal Climate Dynamics.  It uses data from simulations of the CAM5.1-2degree model that were conducted by CASCADE researchers as a pilot project of the international C20C+ Detection and Attribution effort, which CASCADE is managing and to which it has contributed simulations of a higher resolution version of that model.  The study concludes that it is important to assess the role of greenhouse gas emissions using a number of different modelling tools, emphasising the importance of activities like the C20C+ Detection and Attribution project.
