• Arctic greening from warming promotes declines in caribou populations 

      Fauchald, Per; Park, Taejin; Tømmervik, Hans; Myneni, Ranga B.; Hausner, Vera Helene (Journal article; Peer reviewed, 2017)
      Themigratory tundra caribou herds in North America follow decadal population cycles, and browsing from abundant caribou could be expected to counteract the current climate-driven expansion of shrubs in the circumpolar ...
    • Changes in growing season duration and productivity of northern vegetation inferred from long-term remote sensing data 

      Park, Taejin; Ganguly, Sangram; Tømmervik, Hans; Euskirchen, Eugénie S.; Høgda, Kjell Arild; Karlsen, Stein Rune; Brovkin, Victor; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2016)
      Monitoring and understanding climate-induced changes in the boreal and arctic vegetation is critical to aid in prognosticating their future.Weused a 33 year (1982–2014) long record of satellite observations to robustly ...
    • Changes in timing of seasonal peak photosynthetic activity in northern ecosystems 

      Park, Taejin; Chen, Chi; Macias-Fauria, Marc; Tømmervik, Hans; Choi, Sungho; Winkler, Alexander; Bhatt, Uma S.; Walker, Donald A.; Piao, Shilong; Brovkin, Victor; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2019)
      Seasonality in photosynthetic activity is a critical component of seasonal carbon, water and energy cycles in the Earth system. This characteristic is a consequence of plant’s adaptive evolutionary processes to a given set ...

    • China and India lead in greening of the world through land-use management 

      Chen, Chi; Park, Taejin; Wang, Xuhui; Piao, Shilong; Xu, Baodong; Chaturvedi, Rajiv K.; Fuchs, Richard; Brovkin, Victor; Ciais, Philippe; Fensholt, Rasmus; Tømmervik, Hans; Bala, Govindasamy; Zhu, Zaichun; Nemani, Ramakrishna R.; Myneni, Ranga B. (Journal article; Peer reviewed, 2019)
      Satellite data show increasing leaf area of vegetation due to direct factors (human land-use management) and indirect factors (such as climate change, CO2 fertilization, nitrogen deposition and recovery from natural ...
    • Legacies of Historical Exploitation of Natural Resources Are More Important Than Summer Warming for Recent Biomass Increases in a Boreal–Arctic Transition Region 

      Tømmervik, Hans; Bjerke, Jarle W.; Park, Taejin; Hanssen, Frank Ole; Myneni, Ranga B. (Peer reviewed, 2019)
      Eurasian forest cover at high northern latitudes (> 67 N) has increased in recent decades due to stimulatory effects of global warming, but other factors may be important. The objective of this study is to compare the ...
