“…The start time for this analysis, 226,408 years before 1950 (yb1950), is the oldest for which the sampling resolution of the Vostok temperature-proxy record is sufficient to detect centennial-scale events in compliance with the Nyquist-Shannon sampling-frequency criterion of two samples per cycle (SM). Oxygen and hydrogen isotope ratios are used widely and interchangeably as paleoclimate temperature proxies [43][44][45][46][47], although the former contains a proxy component of ice volume and other environmental signals not present in the latter [43,48]. We use both proxies in this study as is conventional.…”

“…Since the establishment of the phosphate δ 18 O thermometer , several revisions of the phosphate-water fractionation and temperature calibration have been published and no consensus has been reached (Pucéat et al, 2010;Lécuyer et al, 2013;Chang and Blake, 2015). Calculation of seawater temperatures in deep time is subject to some uncertainties.…”

“…O seawater is constant at −1‰ (VSMOW), comparisons between calculated temperatures using three different equations Pucéat et al, 2010;Lécuyer et al, 2013) suggest offsets up to 4°C (Supplementary Database S2). But since the δ…”

“…(Lécuyer et al, 2003(Lécuyer et al, , 2013. Together with the fact that these very high SSTs are beyond the mortality limit for diverse marine life (van Geldern et al, 2006) even for high bare-soil albedo values, the effect of a decreasing albedo caused by the evolution of land plants is not strong enough to counteract the cooling effect of the decreasing CO 2 as suggested by Le Hir et al (2011).…”
