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

Changes in growing season duration and productivity of northern vegetation inferred from long-term remote sensing data
Monitoring and understanding climate-induced changes in the boreal and arctic vegetation is critical to aid in prognosticating their future.We used a 33 year (1982–2014) long record of satelliteExpand

Arctic greening from warming promotes declines in caribou populations
A greener Arctic does not benefit caribou; the shift in tundra vegetation due to warming is associated with declining caribou herds. The migratory tundra caribou herds in North America follow decadalExpand
