At a
global scale, increased CO2 concentrations could partially offset expected yield declines caused by lower soil
moisture and higher temperature, but recent models suggest a significantly smaller fertilization effect from CO2 than previously predicted (25).
Benjamin Sulman − a biologist
at Indiana University, but then of the Princeton University Environmental Institute in the US − and colleagues report in Nature Climate Change that they have developed a new computer model to examine what really happens, on a
global scale, when plants colonise the soil and start taking in
moisture and carbon from the atmosphere.
Despite the tremendous effort to collect and homogenize soil
moisture measurements
at global scales (Robock et al., 2000), discrepancies between large -
scale estimates of observed soil
moisture remain.
The researchers, most of them based
at Columbia University's Lamont - Doherty Earth Observatory, say it cements the theory that atmospheric
moisture, and thus dust, move in close step with temperature on a
global scale; the finding may in turn help inform current ideas to seed oceans with iron - rich dust in order to mitigate
global warming.
