For example, atmospheric GCM simulations driven by reconstructed SSTs from the Pliocene Research Interpretations and Synoptic Mapping Group (Dowsett et al., 1996; Dowsett et al., 2005)
produced winter surface air temperature warming of 10 °C to 20 °C at
high northern latitudes with 5 °C to 10 °C increases over the
northern North Atlantic (~ 60 ° N), whereas there was essentially no tropical surface air temperature change (or even slight cooling)(Chandler et al., 1994; Sloan et al., 1996; Haywood et al., 2000, Jiang et al., 2005).
