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 tip** 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 …

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