Missing News: Climate models disputed

ABC yet to cover another important paper. This ones shows Climate models can't hindcast reliably. This  doesn't leave much confidence in their forecasting capacity.
A comparison of local and aggregated climate model outputs with observed data Anagnostopoulos, G. G. , Koutsoyiannis, D. , Christofides, A. , Efstratiadis, A. and Mamassis, N. ‘A comparison of local and aggregated climate model outputs with observed data’,Hydrological Sciences Journal, 55:7, 1094 – 1110
Abstract
We compare the output of various climate models to temperature and precipitation observations at 55 points around the globe. We also spatially aggregate model output and observations over the contiguous USA using data from 70 stations, and we perform comparison at several temporal scales, including a climatic (30-year) scale. Besides confirming the findings of a previous assessment study that model projections at point scale are poor, results show that the spatially integrated projections are also poor.

    Labor media firm claims ABC is even handed in coverage of climate change proponents and sceptics.
