Carbon isotopes of fossil plants and model simulations suggest that atmospheric carbon dioxide levels were variable during the period 200 to 60 million years ago. The large decreases in the partial pressure of CO2 coincide with glaciations, providing evidence against climate–CO2 decoupling during the Mesozoic. 
Convergent Cenozoic CO2 history
Reconstructions of atmospheric carbon dioxide concentrations over the past 65 million years are heading towards consensus. It is time for systematic testing of the proxies, against measurements and
Mesozoic climate: Liverworts and all
The relationship between carbon dioxide and climate over millions of years has been a source of controversy. Fossilized liverwort leaves can help illuminate both temperature and atmospheric carbon

TLDR
As exemplified by the Paleocene-Eocene thermal maximum (PETM) and earlier GHG and temperature spikes associated with major volcanic and asteroid impact events, the long-term residence time of CO2 in the atmosphere extends the signatures of abrupt warming events to within detection limits of multiple paleoproxies.
Geologic constraints on earth system sensitivity to CO 2 during the Cretaceous and early Paleogene
Abstract. Earth system sensitivity (ESS) is the long-term (>103 yr) equilibrium temperature response to doubled CO2. ESS has climate policy implications because global temperatures are not expected
Negative carbon isotope excursions: an interpretive framework
Numerous negative carbon isotope excursions (nCIEs) in the geologic record occurring over 104–105 years are interpreted as episodes of massive carbon release. nCIEs help to illuminate the connection
Atmospheric CO2 concentrations during ancient greenhouse climates were similar to those predicted for A.D. 2100
TLDR
It is reported that greenhouse [CO2]atm have been significantly overestimated because previously assumed soil CO2 concentrations during carbonate formation are too high.

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.

TLDR
The lack of an adequate ancient analogue for future climates means that climate models must be evaluated against modern observation and the authors' best geologic records of warm and cold climates of the past to be able to make reliable predictions of the Earth's response to the climate system.
