Scientific Conference Report The 11th Worlddendro Conference–Beyond Boundaries
The 11th WorldDendro Conference was convened from 28 July to 1 August 2025 at Avani Victoria Falls Resort, Livingstone, Zambia. Organized by the Tree-Ring Society and hosted by the Copperbelt University, this historic edition marked the first WorldDendro meeting held on the African continent. The hybrid conference attracted more than 100 participants from 37 countries representing academia, government, industry, and civil society. Scientific sess…
The Little Ice Age
First coined in the 1930s, with reference to glaciation in North America, the concept of the “Little Ice Age” has undergone continuous revisions. It has traveled academically from glaciology to climatology, archeology, history, and, most recently, climate communication. Over time, it has grown into one of the most discussed topics in the field of climate history and attracts both considerable scholarly interest and public attention. The term “Lit…
Old Wood in a New Light
The Old Wood in a New Light database project focuses on the digitization and accessibility of the results of dendrochronological samples analyzed and archived at four Swedish university-based tree-ring laboratories at Lund University, Stockholm University, University of Gothenburg, and the Swedish University of Agricultural Sciences. Collaboration with the Environmental Archaeology Laboratory and Humlab at Umeå University enables long-term open a…
Impacts of Drought on Maize and Soybean Production in Northeast China During the Past Five Decades
Climate change has a distinct impact on agriculture in China, particularly in the northeast, a key agriculture area sensitive to extreme hydroclimate events. Using monthly climate and agriculture data, the influence of drought on maize and soybean yields-two of the main crops in the region-in northeast China since 1961 to 2017 were investigated. The results showed that the temperature in the growing season increased by 1.0 °C from the period 1998…
Agricultural Adaptation to Global Warming in the Tibetan Plateau
The Tibetan plateau is one of the most sensitive areas in China and has been significantly affected by global warming. From 1961 to 2017, the annual air temperature increased by 0.32 °C/decade over the Tibetan Plateau, which is the highest in the whole of China. Furthermore, this is a trend that is projected to continue by 0.30 °C/decade from 2018 to 2050 due to global warming using the Regional Climate Model version 4 (RegCM4). The increased tem…
A 970-year-long summer temperature reconstruction from Rogen, west-central Sweden, based on blue intensity from tree rings
To assess past climate variability in west-central Scandinavia, a new 972-year-long temperature reconstruction, based on adjusted delta blue intensity (ΔBI adj ), was created. Presently, it is the longest blue intensity chronology in Fennoscandia and the third longest in the northern hemisphere. Measurements were obtained from 119 tree line Scots pine ( Pinus sylvestris L.) samples from Rogen, in the central Scandinavian Mountains, Sweden. Early …

Old World megadroughts and pluvials during the Common Era
An atlas of megadroughts in Europe and in the Mediterranean Basin during the Common Era provides insights into climate variability.
Intensified Arctic warming under greenhouse warming by vegetation–atmosphere–sea ice interaction
Observations and modeling studies indicate that enhanced vegetation activities over highlatitudes under an elevated CO2 concentration accelerate surface warming by reducing thesurface albedo. In this study, we suggest that vegetation-atmosphere-sea ice interactions overhigh latitudes can induce an additional amplification of Arctic warming. Our hypothesis is testedby a series of coupled vegetation-climate model simulations under 2xCO2 environment…
Using adjusted Blue Intensity data to attain high-quality summer temperature information
The inexpensive Blue Intensity proxy has been considered a complement or surrogate to maximum latewood density (MXD), but is associated with biases from differential staining between sapwood and heartwood and also between deadwood samples and living-wood samples that compromise centennial-scale information. Here, we show that, with some minor adjustments, ΔBlue Intensity (ΔBI) is comparable with MXD or ΔDensity (Δ = the difference or contrast bet…

Reconstructions of surface ocean conditions from the northeast Atlantic and Nordic seas during the last millennium
We undertake the first comprehensive effort to integrate North Atlantic marine climate records for the last millennium, highlighting some key components common within this system at a range of temporal and spatial scales. In such an approach, careful consideration needs to be given to the complexities inherent to the marine system. Composites therefore need to be hydrographically constrained and sensitive to both surface water mass variability an…
A 1200-year multiproxy record of tree growth and summer temperature at the northern pine forest limit of Europe
Combining nine tree growth proxies from four sites, from the west coast of Norway to the Kola Peninsula of NW Russia, provides a well replicated (> 100 annual measurements per year) mean index of tree growth over the last 1200 years that represents the growth of much of the northern pine timberline forests of northern Fennoscandia. The simple mean of the nine series, z-scored over their common period, correlates strongly with mean June to August …
Rain-season trends in precipitation and their effect in different climate regions of China during 1961–2008
Using high-quality precipitation data from 524 stations, the trends of a set of precipitation variables during the main rain season (May-September) from 1961 to 2008 for different climate regions in China were analysed. However, different characteristics were displayed in different regions of China. In most temperate monsoon regions (north-eastern China), total rain-season precipitation and precipitation days showed decreasing trends; positive te…
Reconstruction of a regional drought index in southern Sweden since AD 1750
We used a network of eight pedunculate oak ( Quercus robur L.) sites ( n trees = 70) and one Scots pine ( Pinus sylvestris L.) site ( n trees = 53) to develop drought-sensitive master chronologies for the two areas in southern Scandinavia: a SW-area centred on 57°N 12.7°E and a NE-area centred on 58.8°N 18.2°E. The ratio of actual to equilibrium evapotranspiration (AET/EET) was used as a measure of drought during the growing season defined as the…
A high-resolution reconstruction of Storglaciären mass balance back to 1780/81 using tree-ring data and circulation indices
Storglaciären in northernmost Sweden has the world's longest ongoing continuous mass-balance record, starting in 1946. To extend this mass-balance record, we have reconstructed summer ( b S ) and winter ( b W ) mass balances separately back to the mass balance year 1780/81 with annual resolution. We used tree-ring data for b S and a set of circulation indices, based on the sea-level pressure, for b W . Both proxies have correlation coefficients w…
Comparison of high-resolution climate proxies from the Tibetan Plateau and Scandinavia during the last millennium
Tree-ring records from central Fennoscandia
Nine Scots pine tree-ring-width chronologies were compared regarding growth variability and response to climate along a gradient of oceanicity–continentality at 62–64°N in central Fennoscandia. The study revealed higher growth variance and stronger response to climate in the oceanic area west of the Scandi navian Mountains, compared to the more continental areas further east. However, there was a gradual change in radial tree growth and response …
Low-frequency summer temperature variation in central Sweden since the tenth century inferred from tree rings
Living and subfossil Scots pine ( Pinus sylvestris L.) sampled close to the present tree-line in the central Scandinavian Mountains were used to build a continuous 1091-year long tree-ring-width chronology, spanning from ad 909 to 1998. Summer temperatures of the growth year had the highest influence on annual growth. The Håckren chronology represent a record of summer temperatures, where periods of low growth and poor regeneration of pine repres…
