Tree-ring chronologies that represent annual changes in the density of wood formed during the late summer can provide a proxy for local summertime air temperature. Here we undertake an examination of large-regional-scale wood-density/air-temperature relationships using measurements from hundreds of sites at high latitudes in the Northern Hemisphere. When averaged over large areas of northern America and Eurasia, tree-ring density series display a strong coherence with summer temperature… 

Mongolian tree-rings, temperature sensitivity and reconstructions of Northern Hemisphere temperature

Much of northern Asia is lacking in high-resolution palaeoclimatic data coverage. This vast region thus represents a sizeable gap in data sets used to reconstruct hemispheric-scale temperature trends

Trends in recent temperature and radial tree growth spanning 2000 years across northwest Eurasia

It is shown that the extent of recent widespread warming across northwest Eurasia, with respect to 100- to 200-year trends, is unprecedented in the last 2000 years, and an equivalent analysis of simulated temperatures using the HadCM3 model fails to show a similar increase in concordance as a consequence of anthropogenic forcing.

Increased temperature sensitivity and divergent growth trends in circumpolar boreal forests

Tree rings have been used to both reconstruct past climate, and to estimate and project carbon uptake of forest ecosystems. Here we show that large groups of trees of the dominant tree species within

Influence of snowfall and melt timing on tree growth in subarctic Eurasia

The causes of a reduced sensitivity of high-latitude tree growth to variations in summer temperature for recent decades,, compared to earlier this century, are unknown. This sensitivity change is

Climate change and the northern Russian treeline zone

Reconstruction of tree distributions during the HTM suggests that the future position of the treeline due to global warming may approximate its former Holocene maximum position, and an increased dominance of evergreen tree species in the northern Siberian forests may be an important difference between past and future conditions.

The 'Divergence Problem' in tree-ring research

Introduction Evidence for reduced sensitivity of tree growth to temperature has been reported from multiple forest sites along the mid to high northern latitudes and from some locations at higher

Spatial and temporal stability of the climatic signal in northern Fennoscandian pine tree‐ring width and maximum density

The spatial and temporal stability of the climatic signal in pine tree‐ring width and maximum density is examined using data from four sites in northern Sweden and Finland. Moving‐window multiple

Tree-ring width and maximum latewood density at the North American tree line: parameters of climatic change

In remote subarctic North America, instrumental records are very short and sparsely distributed. Yet a long-term understanding of subarctic climate is critical to studies of global change. Annual

Tree-Ring Density Networks for Climate Reconstruction

Conifers from regions with cool-moist summers (all mountains and the boreal conifer belt) are a suitable source of material for building a radiodensitometric tree-ring network in the northern
