The direct effects of warming on ecosystems will also be more complex than the direct effects of increased CO2 because temperature impacts virtually all chemical and biological processes, whereas the direct influence of CO2 is almost entirely limited to leaves (photosynthesis, stomatal aperture, and perhaps respiration; Koch and Mooney 1996).
