TLDR
In this article, the authors analyzed interannual relationships in boreal forest greening and climate over the last three decades using newly available satellite vegetation data and found that due to continued summer warming in the absence of sustained increases in precipitation, a turning point has been reached around the mid-1990s that shifted western central Eurasian boreal forests into a warmer and drier regime.Abstract:
Terrestrial ecosystems in the northern high latitudes are currently experiencing drastic warming, and recent studies suggest that boreal forests may be increasingly vulnerable to warming-related factors, including temperature-induced drought stress as well as shifts in fire regimes and insect outbreaks. Here we analyze interannual relationships in boreal forest greening and climate over the last three decades using newly available satellite vegetation data. Our results suggest that due to continued summer warming in the absence of sustained increases in precipitation, a turning point has been reached around the mid-1990s that shifted western central Eurasian boreal forests into a warmer and drier regime. This may be the leading cause for the emergence of large-scale negative correlations between summer temperatures and forest greenness. If such a regime shift would be sustained, the dieback of the boreal forest induced by heat and drought stress as predicted by vegetation models may proceed more rapidly than anticipated.read more

Understanding Forest Health with Remote Sensing -Part I—A Review of Spectral Traits, Processes and Remote-Sensing Characteristics
TL;DR: An overview of the definitions of FH is provided, discussing the drivers, processes, stress and adaptation mechanisms of forest plants, and how to observe FH with RS, and the concept of spectral traits (ST) and spectral trait variations (STV) in the context ofFH monitoring is introduced.

Variability and evolution of global land surface phenology over the past three decades (1982–2012)
TL;DR: The variability and evolution of satellite-derived growing season length globally and over the past three decades is reviewed and the relative contribution of SOS and EOS to the overall changes are examined, finding that EOS trends were generally stronger and more prevalent than SOS trends.

Seasonal vegetation response to climate change in the Northern Hemisphere (1982–2013)
TL;DR: In this paper, the authors investigated vegetation response to climate change exhibited by temperature, soil moisture, and solar radiation at Northern Hemisphere (NH) scale during the growing season and seasonal periods by analyzing satellite observations of vegetation activity and climatic data.

Trend shifts in satellite-derived vegetation growth in Central Eurasia, 1982-2013.
TL;DR: A persistent increase in the growing season NDVI over Central Eurasia during 1982-1994, whereas this greening trend has stalled since the mid-1990s in response to increased water deficit, which was largely attributed by summer and autumn NDVI changes.

TL;DR: The results indicate that DGVMs may overestimate future wood net primary productivity (NPP) in continental dry regions such as these; this seems to be common feature of current DGV Ms.

A Multiscalar Drought Index Sensitive to Global Warming: The Standardized Precipitation Evapotranspiration Index
TL;DR: In this article, a new climatic drought index, the standardized precipitation evapotranspiration index (SPEI), is proposed, which combines multiscalar character with the capacity to include the effects of temperature variability on drought assessment.

TL;DR: The total forest sink estimate is equivalent in magnitude to the terrestrial sink deduced from fossil fuel emissions and land-use change sources minus ocean and atmospheric sinks, with tropical estimates having the largest uncertainties.

Increased plant growth in the northern high latitudes from 1981 to 1991
TL;DR: In this paper, the authors present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner that is suggestive of an increase in plant growth associated with a lengthening of the active growing season.
