Payne, A. E., M. F. Jansen, and T. W. Cronin (2015): Conceptual model analysis of the influence of temperature feedbacks on polar amplification, Geophys. (sites.uci.edu)
Because while adhering to procedure he allowed the Spencer and Braswell paper «On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance» to be published, as it should have been published. (globalclimatescam.com)
But the notion of «internal forcings» means that what we consider only as temperature feedbacks, as the clouds or the water vapour, might be differentiated from temperature and might depend from others parameters. (gfdl.noaa.gov)
