Technical Abstract: Atmospheric CO2 enrichment tends to lower stomatal conductances of non-woody plants. This response, in turn, reduces plant transpiration rates, resulting in increases in foliage temperatures. It logically follows, therefore, that plants whose stomates are most responsive to CO2 should exhibit the greatest increase in temperature as the CO2 content of the air is raised, just as Idso has demonstrated that such plants exhibit the smallest CO2-induced increase in net photosynthesis. In the absence of a demonstration of such a relationship for a multiplicity of species, it is the purpose of this article to provide an initial quantitative assessment of this phenomenon.
