   the tree-ring stuff will all be collated in 1.1. I would suggest ice core data and varves
   would be better in 1.2  but would like Valerie to comment - in the meantime assume they are
   in 1.2.   1.4 does include peat and rhizopods. The CO2 from stomatal density does not fit
   in the project  - we will get this information from the ice cores.
   Valerie , please comment when you can.  Keith

     Dear Keith,

     Slowly I am getting an overview over Task 1.2
     Yet there are still some points that need clarification from your part:

     -          Does 1.1 include ice-core data, varves and tree rings? I assume so. This
     would then also signify that 1.1 would be responsible to collate long time series of
     tree-ring and varve data in relation to Holocene climate reconstruction
     -          Does 1.4 include peat records and rhizopods? Seeing Dan Charman as one of the
     taskleader I assume so, which would also mean that 1.4 collates these data
     -          What about CO2 reconstructions for the Holocene that do not derive from
     ice-cores? I am thinking of stomatal density derived CO2 records. They would fit into
     1.5 but I am not sure whether the ice-core lobby will be happy to deal with them as they
     tend to show somewhat different results.

     Could you let me have a quick answer?

     Many thanks,

     Andy
