The 20th century was a pivotal period at high northern latitudes as it marked the onset of rapid climatic warming brought on by major anthropogenic changes in global atmospheric composition. In parallel, Arctic sea ice extent has been decreasing over the period of available satellite data records. Here, we document how these changes influenced vegetation productivity in adjacent eastern boreal North America. To do this, we used normalized difference vegetation index (NDVI) data, model…

Monitoring Climate Sensitivity Shifts in Tree-Rings of Eastern Boreal North America Using Model-Data Comparison

The growth of high-latitude temperature-limited boreal forest ecosystems is projected to become more constrained by soil water availability with continued warming. The purpose of this study was to

Sea-ice induced growth decline in Arctic shrubs

An autoregressive plant growth model integrating effects of biological and climatic conditions for analysing individual ring-width growth time series is introduced, finding an overall negative effect of the retreating June sea-ice extent was found on the annual growth.

No growth stimulation of Canada’s boreal forest under half-century of combined warming and CO2 fertilization

An enhanced dependence of forest growth on soil moisture during the late-20th century coincides with a rapid rise in summer temperatures and occurs despite potential compensating effects from increased atmospheric CO2 concentration, emphasizing the ecological sensitivity to regime shifts in the hydrological cycle.

Decadal Variations in Eastern Canada’s Taiga Wood Biomass Production Forced by Ocean-Atmosphere Interactions

It is argued that 20–30 years periodicities in Sea Surface Temperatures as part of the Atlantic Multi-decadal Oscillation (AMO) directly influence heat transfers to adjacent lands, and winter atmospheric conditions associated with the North Atlantic Oscillations might also impact EC’s taiga forests, albeit indirectly, through its effect on SSTs and sea ice conditions in surrounding seas.

Growth dynamics of black spruce (Picea mariana) in a rapidly thawing discontinuous permafrost peatland

High‐latitude warming has led to radical changes in abiotic conditions influencing forest growth. In the North American boreal forest, widespread declines in forest productivity (particularly in



Tundra burning in Alaska: Linkages to climatic change and sea ice retreat

[1] Recent climatic warming has resulted in pronounced environmental changes in the Arctic, including shrub cover expansion and sea ice shrinkage. These changes foreshadow more dramatic impacts that

Circumpolar Arctic Tundra Vegetation Change Is Linked to Sea Ice Decline

Abstract Linkages between diminishing Arctic sea ice and changes in Arctic terrestrial ecosystems have not been previously demonstrated. Here, the authors use a newly available Arctic Normalized

Changes in forest productivity across Alaska consistent with biome shift.

Global vegetation models predict that boreal forests are particularly sensitive to a biome shift during the 21st century. This shift would manifest itself first at the biome's margins, with evergreen

Changes in growth of pristine boreal North American forests from 1950 to 2005 driven by landscape demographics and species traits

Abstract. In spite of the many factors that are occurring and known for positively affecting the growth of forests, some boreal forests across North America have recently felt the adverse impacts of

Temperature‐growth divergence in white spruce forests of Old Crow Flats, Yukon Territory, and adjacent regions of northwestern North America

We present a new 23‐site network of white spruce ring‐width chronologies near boreal treeline in Old Crow Flats, Yukon Territory, Canada. Most chronologies span the last 300 years and some reach the

A synthesis of decadally resolved proxy temperature records from poleward of 60°N covering the past 2000 years indicates that a pervasive cooling in progress 2000 years ago continued through the Middle Ages and into the Little Ice Age.
