Emiliania huxleyi shows identical responses to elevated pCO2 in TA and DIC manipulations (2011, methodology): “The dissociation constants of carbonic acid of Mehrbach et al. (1973) , refit by Dickson and Millero (1987) and the dissociation constants for H 2 SO 4 of Dickson (1990) were used for calculations.”
Where to find 1.5 million yr old ice for the IPICS "Oldest-Ice" ice core (2013, background): “Over this time both climate and greenhouse gases vary mainly in parallel (Loulergue et al., 2008; Petit et al., 1999; Lüthi et al., 2008), with CO2 leading the climate change in the Northern Hemisphere but being in phase (Parrenin et al.”
Sea-level rise due to polar ice-sheet mass loss during past warm periods (2015, background): “temperature [estimates range from slightly cooler than MIS 5e (see below) (36, 37) up to ~2°C warmer than preindustrial (38)] and atmospheric CO2 peaking at 286 ppm (similar to preindustrial values) (39).”
Climate change and ocean acidification effects on seagrasses and marine macroalgae (2013, background): “This [CO2] has not been seen in the atmosphere over the last 800 000 years (Petit et al., 1999; Pearson & Palmer, 2000; Siegenthaler et al., 2005; Lüthi et al., 2008), and the current rate of rise is unprecedented over the last millennium (Doney & Schimel, 2007).”
What caused Earths temperature variations during the last 800,000 years? Data-based evidences on radiative forcing and constraints on climate sensitivity (2009, methodology): “…are measured with a mean temporal resolution better than 1 kyr in ice cores over the last 800 kyr, but N2O exhibits large time windows with no or biased data sets (Petit et al., 1999; Monnin et al., 2001; Siegenthaler et al., 2005; Spahni et al., 2005; Loulergue et al., 2008; Lüthi et al., 2008).”
Orbital forcing and role of the latitudinal insolation/temperature gradient (2009, background): “This suggests models underestimate the role of the LIG in driving polar amplification of global mean temperature through the LTG, and therefore may overestimate the role of Greenhouse gases in driving high latitude warming through global mean temperature over orbital timescales (Lüthi et al. 2008).”
Deconstructing the Last Glacial termination: the role of millennial and orbital-scale forcings (2011, methodology): “The changes in atmospheric CO2 are obtained from the EPICA Dome C ice core, Antarctica (Monnin et al., 2001) on the EDC3 timescale (Lüthi et al., 2008).”
Interactive effects of acidification, hypoxia, and thermal stress on growth, respiration, and survival of four North Atlantic bivalves (2018, background): “Atmospheric CO2 levels have risen from preindustrial levels of ~280 ppm to over 410 ppm today, concentrations that have not been measured on this planet for over a million years (Lüthi et al. 2008, Doney et al. 2009).”
Biological and geophysical feedbacks with fire in the Earth system (2018, background): “Composite records of (a) CO2 and (b) CH4 concentration from Antarctic ice cores (Loulergue et al 2008, Lüthi et al 2008); (c) global biomass burning reconstruction (Daniau et al 2012) showing increasing fire when CO2 and CH4 increase during our present Holocene interglacial; (d) biomass burning…”
