DESCRIPTION:The mid-Pliocene Warm Period (mPWP\, 3.264 to 3.025 Myr ago) h
 as been extensively studied through the use of general circulation models 
 (GCMs). Whilst the output from these simulations replicates closely many o
 f the patterns of the climate of the interval indicated by proxy data\, at
  northern high latitudes the reconstructed proxy data temperatures exceed 
 the model temperatures by over 15ºC for some sites.\n\nThis data-model di
 screpancy highlights the importance of focusing on model representation of
  processes that strongly affect the northern high latitude climates\, such
  as sea. Results are presented from simulations of the mPWP with the GCM H
 adCM3 focusing on the climatic effects of changes to the parameterisation 
 of sea ice albedo\, in isolation and in combination with orbital and atmos
 pheric CO2 uncertainties.\n\nSimulated Arctic sea ice outputs from eight d
 ifferent GCMs as part of the Pliocene Modelling Intercomparison Project (P
 lioMIP) are presented\, to demonstrate model dependency on past Arctic sea
  ice simulation.
