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 …

The productivity of ecosystems and their capacity to support life depends on access to
reactive nitrogen (N). Over the past century, humans have more than doubled the global …

Climate tipping points occur when change in a part of the climate system becomes self-
perpetuating beyond a warming threshold, leading to substantial Earth system impacts …

It is unequivocal that the increases in atmospheric carbon dioxide (CO2), methane (CH4)
and nitrous oxide (N2O) since the pre-industrial period are caused by human activities. The …

The enhanced vegetation productivity driven by increased concentrations of carbon dioxide
(CO2)[ie, the CO2 fertilization effect (CFE)] sustains an important negative feedback on …

Terrestrial ecosystems remove about 30 per cent of the carbon dioxide (CO2) emitted by
human activities each year, yet the persistence of this carbon sink depends partly on how …

The ratio of carbon assimilation to water evapotranspiration (ET) of an ecosystem, referred to
as ecosystem water use efficiency (WUEeco), is widely expected to increase because of the …

The visual deficiency symptoms developing on plants constitute the ultimate manifestation of
suboptimal nutrient supply. In classical plant nutrition, these symptoms have been …

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

Atmospheric carbon dioxide concentration ([CO2]) is increasing, which increases leaf‐scale
photosynthesis and intrinsic water‐use efficiency. These direct responses have the potential …
