Read More The Impact of Elevated CO2 on Forest Arthropod Communities (5 Mar 2013) According to the authors of this study, “decreases in herbivorous arthropods and increases in predaceous arthropods ...

As more data become available, and as more researchers strive to decipher what those data imply, the search appears ever more futile... Read More The Net Effect of Simultaneous Increases in Air Temperature and CO2 Concentration on Plant Biomass Production (26 Feb 2013) How does it compare with the individual effects of ...

How would they likely compare with the region’s winter wheat yields of today? Based on the results of this study, the net effect of several warmth-induced changes induces a mean grain yield increase of 16.3%...
