Title: The space-time continuum: climate change effects on trees and the importance of scaling

Abstract: To predict how forests will respond to rising temperatures and atmospheric CO2 concentrations, we need to understand how trees respond to both of these environmental factors. I'll discuss the importance of scaling, moving from leaf-level responses to those of the canopy, and from short-term to long-term responses of vegetation to climate change. While our knowledge of leaf-level, instantaneous responses of carbon and water fluxes to elevated CO2 and temperature is quite good, our ability to scale these responses up to larger spatial and temporal scales is less developed. Ignoring the spatial or temporal scale of a physiological process impedes our ability to predict how forest carbon and water fluxes will be altered in the future, and I'll also argue that we need to move beyond single factorial experiments whenever possible, combining both CO2 and temperature treatments in studies of tree performance.
