Evidence, causes, and consequences of declining nitrogen availability in terrestrial ecosystems
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 …

30 years of free‐air carbon dioxide enrichment (FACE): What have we learned about future crop productivity and its potential for adaptation?
Free‐air CO2 enrichment (FACE) allows open‐air elevation of [CO2] without altering the
microclimate. Its scale uniquely supports simultaneous study from physiology and yield to …

Impact of anthropogenic CO2 emissions on global human nutrition
Atmospheric CO2 is on pace to surpass 550 ppm in the next 30–80 years. Many food crops
grown under 550 ppm have protein, iron and zinc contents that are reduced by 3–17 …
