Royer et al. (2004) introduce a seawater pH correction to the Phanerozoic temperature reconstruction based on δO variations in marine fossils. Although this correction is a novel idea and it is likely to have played some role in offsetting the δO record, we show that (a) The correction cannot be as large as claimed by Royer et al. (b) Irrespective of the size of the correction, a CO2 signature cannot possibly be seen in the data. (c) Even though the CO2 signature cannot be seen, the pH…

Siberian glaciation as a constraint on Permian–Carboniferous CO2 levels
Reconstructions of Phanerozoic CO2 levels have generally relied on geochemical modeling or proxy data. Because the uncertainty inherent in such reconstructions is large enough to be climatically
On the absence of solar evolution‐driven warming through the Phanerozoic
Reconstructed temperatures through the Phanerozoic indicate a gradual cooling or, at best, no significant temperature trend, despite a 4.4% increase in solar heating. It is possible that an
Geologic constraints on the glacial amplification of Phanerozoic climate sensitivity
The long-term carbon cycle depends on many feedbacks. Silicate weathering consumes atmospheric CO2, but is also enhanced by the increased temperatures brought about by this important greenhouse gas.

Herold et al. (2009) consider factors underlying the midMiocene climate optimum (MMCO), comparing atmospheric paleo-CO2 levels [Pagani et al. 1999 (pre-10 Ma: 5300 ppm CO2); Royer et al. 2001 (18–14
Isotopic evidence for long term warmth in the Mesozoic
TLDR
The results are consistent with a warm climate mode for the Jurassic and Cretaceous and hence support the view that changes in atmospheric CO2 concentrations are linked with changes in global temperatures.
A mechanism for brief glacial episodes in the Mesozoic greenhouse
[1] The Mesozoic, perhaps the longest period of warmth during the Phanerozoic Earth history, has been repeatedly affected by short-lived cold interludes lasting about one million years. While the
Simulating the Climate Response to Atmospheric Oxygen Variability in the Phanerozoic
Abstract. The amount of dioxygen (O2) in the atmosphere may have varied from as little as 10 % to as high as 35 % during the Phanerozoic eon (541 Ma–Present). These changes in the amount of O2 are
Simulating the climate response to atmospheric oxygen variability in the Phanerozoic: a focus on the Holocene, Cretaceous and Permian
Abstract. The amount of dioxygen (O2) in the atmosphere may have varied from as little as 5 % to as much as 35 % during the Phanerozoic eon (54 Ma–present). These changes in the amount of O2 are

Celestial driver of Phanerozoic climate
Atmospheric levels of CO2 are commonly assumed to be a main driver of global climate. Independent empirical evidence suggests that the galactic cosmic ray flux (CRF) is linked to climate variability.

Evidence for decoupling of atmospheric CO2 and global climate during the Phanerozoic eon
TLDR
A reconstruction of tropical sea surface temperatures throughout the Phanerozoic eon (the past ∼550 Myr) from the database of oxygen isotopes in calcite and aragonite shells indicates large oscillations of tropicalSea surface temperatures in phase with the cold–warm cycles, thus favouring the idea of climate variability as a global phenomenon.
