Low-Frequency Signals in Long Tree-Ring Chronologies for Reconstructing Past Temperature Variability
- J. Esper, E. Cook, F. Schweingruber
- Environmental ScienceScience

TLDR
Influence of volcanic eruptions on Northern Hemisphere summer temperature over the past 600 years
- K. Briffa, P. Jones, F. Schweingruber, T. Osborn
- Environmental ScienceNature
- 4 June 1998
A network of temperature-sensitive tree-ring-density chronologies provides circum-hemisphere information on year-by-year changes in summer warmth in different regions of the northern boreal forest.…
Fennoscandian summers from ad 500: temperature changes on short and long timescales
Quantitative estimates of 1480 years of summer temperatures in northern Fennoscandia have previously been derived from continuous treering records from northern Sweden. Here we show the results of…
Tree Rings: Basics and Applications of Dendrochronology
- F. Schweingruber
- Environmental Science
- 31 January 1988
I Origin of the materials.- II Analysis of the materials.- III Tree-ring growth and the site.- IV Applied dendrochronology.- V History of dendrochronology.- General Index.
Low-frequency temperature variations from a northern tree ring density
- K. Briffa, T. Osborn, E. Vaganov
- Environmental Science
- 16 February 2001
We describe new reconstructions of northern extratropical summer temperatures for nine subcontinental-scale regions and a composite series representing quasi “Northern Hemisphere” temperature change…
Carbon isotope discrimination indicates improving water‐use efficiency of trees in northern Eurasia over the last 100 years
- M. Saurer, R. Siegwolf, F. Schweingruber
- Environmental Science
- 1 December 2004
We investigated the response of conifer trees in northern Eurasia to climate change and increasing CO2 over the last century by measuring the carbon isotope ratio in tree rings. Samples from Larix,…
Reduced sensitivity of recent tree-growth to temperature at high northern latitudes
- K. Briffa, F. Schweingruber, P. Jones, T. Osborn, S. Shiyatov, E. Vaganov
- Environmental ScienceNature
- 12 February 1998
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…
Influence of snowfall and melt timing on tree growth in subarctic Eurasia
- E. A. Vaganov, M. Hughes, A. Kirdyanov, F. Schweingruber, P. Silkin
- Environmental ScienceNature
- 8 July 1999
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…
A 1,400-year tree-ring record of summer temperatures in Fennoscandia
- K. Briffa, T. Bartholin, P. Zetterberg
- Environmental ScienceNature
- 1 August 1990
Tree-ring data have been used to reconstruct the mean summer (April-August) temperature of northern Fennoscandia for each year from AD 500 to the present. Summer temperatures have fluctuated markedly…
