SUMMARY:Paleocene–Eocene climate and carbon cycle: tales from the 'borin
 g background' - Kate Littler\, University of Exeter

DESCRIPTION:The Paleocene and Eocene Epochs (~66–34 Ma) were important g
 reenhouse periods\, characterised by high frequency orbitally-paced events
  (e.g.\, hyperthermals) superimposed on long term changes in climate and t
 he carbon cycle. Major changes in the marine and terrestrial biosphere als
 o occurred at this time\, synchronous with both high frequency and long-te
 rm changes in climate. While many detailed palaeoclimate records have been
  generated for the enigmatic hyperthermals\, such as the Paleocene Eocene 
 Thermal Maximum (PETM)\, the general background climate of this period has
  only been reconstructed at a much lower resolution. This poorly character
 ised 'boring background' hampers our understanding both of the overall cli
 mate state of this greenhouse world and the hyperthermals themselves. Here
  I'll talk through some new data from the ancient Atlantic and Indian Ocea
 ns which help to better characterise background climate and carbon-cycle o
 f the Palaeocene–Eocene.\n\nThree supporting papers:\n\nhttps://agupubs.
