SCOT2K: Reconstructing 2000 years of Scottish climate from tree-rings

Lead Research Organisation: University of St Andrews
Department Name: Earth and Environmental Sciences

Abstract

The SCOT2K project aims to reconstruct summer temperatures in the Scottish Highlands for the last 2000 years using tree-ring data. Such a climate reconstruction for Northern Britain, along with similar tree-ring data-sets being developed in Scandinavia, will not only provide important information on medieval climate, the transition into the Little Ice Age (~1300 AD) and current regional climate change, but will also help ascertain the influence of the North Atlantic on the climate of the NW European region.

Trees respond to a variety of environmental factors. By understanding how these organisms respond to such factors, it is possible to use tree-ring measurements to not only reconstruct past climate but also assess how management practises may have influenced tree-growth in the past. In the Scottish Highlands, Scots pine trees rarely attain ages greater than ~200-300 years. Therefore, to study past environmental change prior to ~1700, living pine chronologies need to be extended back in time using preserved local woody material. There are potentially two sources of material; historic timbers from buildings and sub-fossil material preserved in peat/lake sediments. This project will utilise both sources of preserved pine material to extend the living chronologies back in time.

In general, trees of the same species respond in a similar way to environmental conditions over relatively large areas. There is therefore a certain degree of common growth variability between all trees of the same species from the same region. This common variability results in a shared pattern of wide and narrow rings (i.e. like a bar code) that can be matched between samples allowing between sample dating. This synchronising or pattern matching process is termed "crossdating". Through crossdating, historical or sub-fossil woody material can be calendar dated, so long as there is reasonable overlap (~80 years) with an already dated reference chronology.

Initial results indicate that a 2000 year chronology is a feasible and realistic objective within the timeframe of the proposed SCOT2K project and that an ~8000 year long chronology, an albeit more challenging long term aim, is theoretically possible in the future.

This project proposes to sample preserved pine material from both historic structures and lakes in the Scottish Highlands, crossdate the samples and derive a 2000-year long climatically sensitive tree-ring chronology for the region. As well as ring-width (RW) data, maximum density (MXD) and minimum blue intensity (BI) data will also be measured from the samples. MXD and BI are both measures of lignin content in the latewood of a tree-ring, the amount of which is strongly controlled by summer temperatures. Using RW, MXD and BI, a robust, strongly calibrated summer temperature reconstruction can be developed for the Scottish Highlands. The data obtained from the SCOT2K project will not only provide important information of past temperatures over the last two millennia for northern Britain, but will also provide key information on North Atlantic variability which controls decadal and longer term climate variability over the British Isles. The importance of this work will be greatly enhanced by interaction with research groups (other tree-ring scientists and climate modellers) undertaking similar research across Scandinavia. A synthesis workshop is proposed for Year 3 of the project to facilitate this important collaboration.

Planned Impact

There are three main User groups who would benefit from this research:

a. The palaeoclimate community:
A 2000 year tree-ring based summer temperature record for Scotland, as well as similar records from Scandinavia, will provide important information on the influence of the Atlantic Ocean (and related internal models of variability, e.g. North Atlantic Oscillation) on NW European terrestrial climate, especially for the Medieval and Little Ice Age periods. A workshop is planned for year 3 of the project to bring together dendrochronologists from the UK and Scandinavia to undertake a regional synthesis of available millennial length tree-ring reconstructions for the NW European sector.

Project Partners Moberg and Zorita will also be invited to this workshop to provide important input from the modelling community. Although there is no specific modelling element proposed within this project, the tree-ring based reconstruction will have utility for proxy/climate model synthesis and attribution studies that are currently being undertaken by these two groups. As well the project partners, the reconstruction from this project will be made available through appropriate NOAA and NERC data archives for other climate modelling and palaeoclimate user groups. The data will also be particularly relevant for the PAGES2K Network initiative (http://www.pages-igbp.org/workinggroups/2k-network).

b. Scottish archaeologists:
Dendrochronology provides a powerful method of dating historic material. However, for dendro-methods to be successful, a valid exactly dated reference chronology is required. At this time, the pine chronology for Rothiemurchus is not replicated enough to allow robust dating prior to ~1650 AD. The SCOT2K project will improve the replication in the Scots pine chronology greatly. The University of St Andrews tree-ring laboratory is already collaborating with archaeologists (Project Partner Anne Crone and proposed PDRA Dr. Coralie Mills) and the development of a long pine ring-width (and Blue Intensity) composite chronology will enable the robust dating of many structures that currently remain undated.

c. Land owners and the local community:
There is great local (individuals and landowners) interest in archaeology, landscape history, woodland change and climate change and through freely available reports (via the project website), public presentations and a proposed community outreach workshop the main results of the SCOT2K project will be communicated to the public. This is potentially very important as interaction with the public may facilitate the further identification of both relevant historic buildings and lakes with sub-fossil pine material that can be targeted for sampling.

Description We have further developed the Blue Intensity parameter for Dendrochronology.
We have also derived a new method to identify and detect for human disturbance in forest to facilitate tree-ring reconstruction of past climate.
Summer temperatures in Scotland for the last decade are NOT unique when compared to the last 800 years.
Exploitation Route The new Scottish data have already been used in a new Northern Hemisphere reconstruction. Part I was published in 2016 and Part II in 2017.
