Nature article: Forcing, feedback and internal variability in global temperature trends

Rather than the increase in Global-Mean Surface Temperature (GMST) simulated by climate models, recent observations suggest a warming hiatus.

In this latest paper, Forcing, feedback and internal variability in global temperature trends, published in Nature, authors Piers Forster (IAGP Principal Investigator)
and Jochem Marotzke, MPI, compared climate observations with simulated 15-year trends over the period 1900-2012. They noted that the differences between simulated and observed 15-year trends in GMST are dominated by internal variability and due largely to coincidence. The research concluded that the claim that climate models systematically overestimate the response to radiative forcing from increasing greenhouse gas concentrations seems unfounded.
