   Dear Dr Ogilvie,

   I am writing on behalf of the Director , Professor Philip Jones to say that The Climatic
   Research Unit would be very happy to collaborate on the project you propose:  Understanding
   Climate-Driven Phenological Change - Observations, Adaptations and Cultural Implications in
   Northeastern Siberia and Labrador/Nunatsiavut (PHENARC).
   This Unit, as you are well aware possesses large holdings of instrumental climate records
   at individual station locations and in wider gridded form , representing a range of spatial
   and temporal resolutions and covering all of the regions appropriate to your proposed
   research. We also have extensive experience in the interpretation and analysis of high (ie.
   annual) -resolution proxy climate data - with a relevant focus in this case, on the
   production of tree-ring and tree-ring-density records that provide strong indications of
   summer temperature variability in various regions of northern Eurasia , spanning time
   periods ranging up to several millennia.
    We have published various papers describing the nature of warming patterns , changing
   seasonality (particular in the characteristics of "growing season" changes), and the
   reconstruction and simulation of past and future warming characteristics in North America
   and Eurasia. I include a selection of relevant references below.
    I feel sure that our co-operation would result in profitable scientific advances in the
   analysis of the nature and consequences of climate changes in these northern areas. I wish
   you success with your application.
   sincerely
   Keith. R. Briffa
   Deputy Director,
   Climatic Research Unit
