John just published a paper in New Phytologist with five collaborators. They used a carbon isotopic pulse-chase experiment to label the photosynthate of six trees on a single afternoon, and then they "chased" that label as it was transported and respired by each tree over the following month.
The results indicate that trees have substantial ability to adjust their physiology in response to climate warming. Because of the way trees acclimate their physiology to warming, warming actually does not strongly impact how trees take up, distribute, or respire carbon dioxide. These results indicate that at least some trees can cope with warmer temperatures without negative consequences on their growth or physiology. You can find the paper on "early view" here. Note that this link will probably be broken in a few months. In the longer-term, you can access the paper here.
