DESCRIPTION:The West Antarctic Ice Sheet (WAIS) is thinning at an accelera
 ting rate\, and several numerical models suggest that full ice sheet colla
 pse could be underway. Two of the region’s largest ice streams\, Thwaite
 s Glacier (aka Doomsday Glacier) and neighbouring Pine Island Glacier\, ha
 ve long been considered the weak underbelly of WAIS\, and should they coll
 apse\, would raise global sea level by over 1 m. However\, with only a few
  decades of observational data\, it remains uncertain whether the changes 
 we are seeing are irreversible\, or whether the ice sheet has a propensity
  to self-stabilise and possibly readvance. In this talk I will present res
 ults of palaeo studies from the Amundsen Sea sector of WAIS which help to 
 put these recent changes into a longer-term context. While the palaeo reco
 rd reveals a range of dynamical behaviour(s) – some similar to the prese
 nt day - it also serves to highlight that the current phase of anthropogen
 ic warming is driving large scale\, and potentially\, irreversible ice she
 et retreat.
