Uptake Of CO2 By Trees May Be Substantially Overstated; Study Found Growth Stopped Months Before Photosynthesis Did

1. That's crazy

I watch my trees sometimes closely, when pruning. Growth in bark swells well into the fall, when the leaves have been drying for 2-1/2 months. In spring the sap goes up and makes leaves, which then collect sunlight. Then the leaves stop growing, and the sap returns to the roots. The new wood growth in several species is light brown or even orange.
