Termination of global warmth at the Palaeocene/Eocene boundary through productivity feedback
Article Abstract:
Research is presented concerning the response of the Earth to global warming at the boundary of the Palaeocene/Eocene periods. The occurrence of enhanced deposition of organic matter to the deep sea and the subsequent cooling of the climate is discussed.

Abrupt reversal in ocean overturning during the Palaeocene/Eocene warm period
Article Abstract:
The evidence for an abrupt shift in deep-ocean circulation is presented using carbon isotope records from fourteen sites. These records indicates that deep-ocean circulation patterns changed from Southern Hemisphere overturning to Northern Hemisphere overturning at the start of the Palaeocenc/Locene Thermal Maximum.

Carbon cycling and chronology of climate warming during the Palaeocene/Eocene transition
Article Abstract:
Chemical, physical and spectral analysis of a sediment core from the North Atlantic indicates that 66% of the carbon-isotope anomaly took place within just a few thousand years. This means that carbon was emitted into the atmosphere and the ocean catastrophically. It would appear that the global carbon cycle suffered natural disturbances at similar rates to those for which human activity has been responsible in recent times.
