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 …

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

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 …

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 …

Climate policy has thus far focused solely on carbon stocks and sequestration to evaluate
the potential of forests to mitigate global warming. These factors are used to assess the …

Executive summary Land and climate interact in complex ways through changes in forcing
and multiple biophysical and biogeochemical feedbacks across different spatial and …

In the context of a recent massive increase in research on plant root functions and their
impact on the environment, root ecologists currently face many important challenges to keep …

Abstract The Community Land Model (CLM) is the land component of the Community Earth
System Model (CESM) and is used in several global and regional modeling systems. In this …

Abstract Elevated CO2 (eCO2) experiments provide critical information to quantify the effects
of rising CO2 on vegetation,,,,–. Many eCO2 experiments suggest that nutrient limitations …

Because of human action, the Earth has entered an era where profound changes in the
global environment are creating novel conditions that will be discernable far into the future …
