Delamere, P. A. & Bagenal, F. Modeling variability of plasma conditions in the Io torus. (nature.com)
One of the draft AR5 figures (the one reworked due to baseline errors, mind you) showed HadCRUT4 variability for the 2 - sigma bounds around the model mean rather than model variability. (realclimate.org)
As often the observed and modelled variability is pointed out it doesn stop stupid remarks such as this citation stemming apparently from David Whitehouse. (realclimate.org)
