Overestimated global warming over the past 20 years (2013)

What this document is

This is a short commentary titled ‘Overestimated global warming over the past 20 years’, written by John C. Fyfe, Nathan P. Gillett and Francis W. Zwiers. It appeared in the opinion and comment section of the journal Nature Climate Change, volume 3, September 2013.

The commentary observes that recent observed global warming was slower than that simulated by the climate models participating in Phase 5 of the Coupled Model Intercomparison Project (CMIP5), and suggests this difference might be explained by some combination of errors in external forcing, model response and internal climate variability.
