Global annual mean temperature variation of the Earth through time last 400 million

Global annual mean temperature variation of the Earth through time (last 400 million years) predicted by the Hadley Centre Coupled Climate Model version 3 (HadCM3), compared with geologically derived estimates of temperature variability over the same period [the Royer et al. 2004 temperature record, the Zachos et al. 2008; Lisiecki and Raymo 2005 benthic oxygen isotope stack, as well as the EPICA and NGRIP ice core records; Jouzel et al. 2007 and NGRIP Members 2004. Geological epochs include the Devonian (D), Carbon Figure from Haywood, AM & Valdes, Paul & Aze, T & Barlow, N & Burke, Ariane & Dolan, Aisling & Heydt, Anna S. & Hill, Daniel & Jamieson, SSR & Otto-Bliesner, BL & Salzmann, U & Saupe, Erin & Voss, J.
