(Presumably the work was started around 2004 and it took some time for the paper to be published). The paper made claims about the “skill” of the model, for example “Having established the predictive skill of DePreSys…

  • There would be 0.3°C warming over the decade 2004-2014
  • At least half of the years after 2009 would be warmer than the record year of 1998.
