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… Expand
Post-1980 shifts in the sensitivity of boreal tree growth to North Atlantic Ocean dynamics and seasonal climate
Abstract The mid-20th century changes in North Atlantic Ocean dynamics, e.g. slow-down of the Atlantic meridional overturning thermohaline circulation (AMOC), have been considered as early signs ofExpand
Winter precipitation effect in a mid-latitude temperature-limited environment : the case of common juniper at high elevation in the Alps
The area covered by boreal forests accounts for∼16%of the global and 22%of theNorthern Hemisphere landmass. Changes in the productivity and functioning of this circumpolar biome not only have strongExpand
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. Expand
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 toExpand
Rapid 21st century climate change projected to shift composition and growth of Canada’s Acadian Forest Region
Abstract The impact of climate change on forests is expected to vary globally and regionally. Canada’s Acadian Forest Region lies in the transition between the North American boreal and temperateExpand
Recent rising temperatures drive younger and southern Korean pine growth decline.
Results showed a significant decline in BAI in most sites coinciding with an increase of temperature in the growing season and a decrease in precipitation since the 1980s, and found that temperature-induced growth decline was significantly related to tree age. Expand
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.

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 inExpand
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.

Abstract Stress from water scarcity as a result of rising temperatures associated with climate change has a profound impact on forest ecosystems around the world. However, few studies have assessedExpand


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 thatExpand
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 NormalizedExpand
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 evergreenExpand
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 ofExpand
Impact of Future Climate on Radial Growth of Four Major Boreal Tree Species in the Eastern Canadian Boreal Forest
The modeling approach provides a template to predict tree growth response to climate warming at mid-high latitudes of the Northern Hemisphere. Expand

Massive mortality of aspen following severe drought along the southern edge of the Canadian boreal forest
Drought-induced, regional-scale dieback of forests has emerged as a global concern that is expected to escalate under model projections of climate change. Since 2000, drought of unusual severity,Expand
Spring temperature change and its implication in the change of vegetation growth in North America from 1982 to 2006
Using observed climate data and satellite-derived Normalized Difference Vegetation Index (NDVI) data from 1982 to 2006, changes in spring (April–May) temperature trends and their impact on vegetation growth in NA are investigated. Expand

Recent Warming Reverses Long-Term Arctic Cooling
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. Expand
