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.
