A brief period of warming 55.9 Myr ago has been attributed to the release of massive amounts of carbon. Geochemical and model data suggest the peak rate of carbon emission during this interval was relatively slow, and significantly lower than present-day levels of carbon emissions to the atmosphere. 
Two massive, rapid releases of carbon during the onset of the Palaeocene–Eocene thermal maximum
The release of massive amounts of carbon led to abrupt warming 55.5 million years ago. An analysis of soil carbonates shows two distinct carbon injections at the event onset, each releasing over 0.9
Carbon sequestration during the Palaeocene-Eocene Thermal Maximum by an efficient biological pump
Globally increased temperatures and a perturbation of the carbon cycle and biosphere characterized the Palaeocene–Eocene Thermal Maximum about 55.9 million years ago, but its effect on ocean

A period of rapid warming about 55.5 million years ago was triggered by a massive release of carbon. The carbon isotope composition of soil nodules provides evidence for a smaller, but still
Constraints on hyperthermals
The abrupt warming event 56 million years ago, known as the Palaeocene–Eocene Thermal Maximum (PETM), was associated with the large scale release of 13C-depleted carbon into the ocean–atmosphere
Palaeocene–Eocene Thermal Maximum prolonged by fossil carbon oxidation
A hallmark of the rapid and massive release of carbon during the Palaeocene–Eocene Thermal Maximum is the global negative carbon isotope excursion. The delayed recovery of the carbon isotope
A middle Eocene carbon cycle conundrum
A 500,000-year-long period of warmth in the middle Eocene was marked by high atmospheric carbon dioxide concentrations and prolonged dissolution of carbonate in the deep oceans. Numerical simulations
Palaeoclimate: Volcanism caused ancient global warming
A study confirms that volcanism set off one of Earth's fastest global-warming events. But the release of greenhouse gases was slow enough for negative feedbacks to mitigate impacts such as ocean
A multi-proxy study of the Palaeocene - Eocene Thermal Maximum in northern Spain
The Palaeocene – Eocene Thermal Maximum (PETM), a hyperthermal event that occurred ca. 56 Ma, has been attributed to the release of substantial amounts of carbon, affecting the atmosphere, biosphere
Tertiary Hyperthermal Events: Precursors of the Current Situation?
The focus of this study is based on a detailed analysis of the hyperthermal events of the Paleocene / Eocene limit of 56 Ma and the lower Eocene (for the 54-52 Ma interval, Figure 1). This example

Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene
TLDR
Stable carbon isotopic values of di-unsaturated alkenones extracted from deep sea cores are used to reconstruct pCO2 from the middle Eocene to the late Oligocene and demonstrate that it ranged between 1000 to 1500 parts per million by volume in the middle to late Eocene, then decreased in several steps during theOligocene, and reached modern levels by the latest Oligaen.

TLDR
