Plant respiration contributes several times the amount of carbon emissions to the atmosphere as anthropogenic sources. Respiration also increases with temperature, leading to a positive feedback loop. However, plants can acclimatize to warmer temperatures and reduce their respiration rate. Using a model based on ecological-evolutionary optimality principles, we predicted the rate of respiration acclimation to warming driven by decreasing water viscosity within the plant. We then tested these predictions using a dataset of stem respiration measurements from 186 woody plant species collected in the field and laboratory. Incorporating thermal acclimation into emissions projections reduced the predicted terrestrial carbon emissions estimate by nearly one third.
