less than previous estimates for this event.

warmer than previous estimates derived from empirical proxies (Ballantyne et al., 2006; Elias and Matthews, 2002) and climate model simulations (Haywood et al., 2009), despite estimates of Pliocene atmospheric CO2 levels that are comparable to today (Pagani et al., 2010).
