Climate change has been partially mitigated by an increasing net land carbon sink in the
terrestrial biosphere; understanding the processes that drive this sink is thus essential for …

Vegetation greenness has been increasing globally since at least 1981, when satellite
technology enabled large-scale vegetation monitoring. The greening phenomenon, together …

2 Chapter 2 assesses observed large-scale changes in climate system drivers, key climate
indicators and 3 principal modes of variability. Chapter 3 considers model performance and …

The AR5 concluded that human influence on the climate system is clear, evident from
increasing greenhouse gas concentrations in the atmosphere, positive radiative forcing …

Plant phenology, the annually recurring sequence of plant developmental stages, is
important for plant functioning and ecosystem services and their biophysical and …

Fossil fuel combustion, land use change and other human activities have increased the
atmospheric carbon dioxide (CO2) abundance by about 50% since the beginning of the …

Several lines of evidence point to an increase in the activity of the terrestrial biosphere over
recent decades, impacting the global net land carbon sink (NLS) and its control on the …

Chinese forests, characterized by relatively young stand age, represent a significant
biomass carbon (C) sink over the past several decades. Nevertheless, it is unclear how …

Human activities result in a wide array of pollutants being released to the atmosphere. A
number of these pollutants have direct effects on plants, including carbon dioxide (CO 2) …

Global climate change is influencing the seasonal cycle amplitude of atmospheric CO2
(SCA), with the strongest increases at northern high latitudes (NHL;> 45° N). In this Review …
