 ===== Group description =====
-Climate variability and its relation to the mean state
+The primary focus of PMIP efforts so far has been to look at changes in the mean climate and how these are modelled. However, GCMs also simulate internal variability about that mean state. Its study requires both high resolution proxy data and the storing of larger model datasets - which has been developing through the PMIP iterations.
+The purpose of this working group is to encourage and facilitate the study of past climate variability: either amongst models or between models and data.
+Historical footnote: group initiated at the PMIP3 2012 Crewe meeting.
+===== Actions =====
+=== Establishing the present cutting edge of PalaeoENSO research ===
+  * Status: Complete
+  * Contact: Pascale Braconnot, Sandy Harrison, Chris Brierley
+Before identifying where the working group should focus its efforts, it was necessary to map the current research landscape. We therefore invited the leading PalaeoENSO researchers to contribute pieces to a collection. This collections appears in the August 2013 issue of the [[http://www.pages-igbp.org/products/pages-news/1360-21-2-el-niño-southern-oscillation|PAGES newsletter]].
+=== Investigation into the methodology of model-data comparisons for PalaeoENSO ===
+   * Status: Publication in preparation
+   * Contact: Julien Emile-Geay
+How should one combine and contrast the different sources of information on past ENSO variability? How should one marry simulations with observations across different periods?

+=== Do simulations show additional modes of variability in the past? ===
+  * Status: Being contemplated
+  * Contact: Chris Brierley
-===== More =====
+A great advantage of palaeoclimate observations has been the discovery of unforeseen climate transitions and variability. One example of this is the discovery of millenial scale variability in glacial conditions. Currently no systematic tool exists to look for new modes of variability across palaeoclimate simulations. How could we address this?
