Tree-ring evidence of climate change in northern eurasia during the last 2000 years

Obiettivo

To describe the natural variability of climate, both temperature
and precipitation (or precipitation-related) variables, over
various parts of northern Eurasia for periods up to 2000 years
before present.


The emphasis will be on relatively high-resolution (annual or
seasonal) analyses. Instrumental records will be examined but
the principal focus is the collection and exploration of
tree-ring-related evidence to reconstruct local, regional-mean
and large-scale patterns of climate change and to explore
statistical links with various potential forcings such as solar
variability, volcanism and other internally-driven processes such
as the North Atlantic thermohaline circulation.

The overall project will bring together evidence from three major
sub-projects, each with a particular emphasis on a different
tree-ring variable.

A 'northern' project will assemble and analyze a network of
mainly densitometric chronologies in northern Fennoscandia and
Siberia. Through the development of statistical multivate
transfer functions, these largely temperature sensitive data will
yield reconstructions of spatial patterns of temperature
variability for periods ranging from hundreds to thousands of
years across a wide longitudinal range.

A 'central' project will assemble and reprocess existing
ring-width data, mainly on oak (of living, historical and
sub-fossil origin) principally from sites in Great Britain,
Denmark, Germany and Poland. These data will be used to document
changes in the natural variability of temperature and moisture
conditions during the last two millennia.

The third sub-project will undertake a preliminary systematic
investigation of the potential for interpreting stable isotope
composition (carbon and oxygen) in wood cellulose from individual
tree rings. Isotopic measurements will be made on replicate oak
trees at each of two contrasting sites from three west European
regions. This sub-project will be constrained by the length of
available climate records against which these data must be
compared and will concentrate on the last 100 years.
