Researchers found that at sites in the eastern US, about 36% of annual carbon uptake occurred after wood growth stopped in late summer, with growth ceasing months before photosynthesis ended. Across 137 US sites, wood growth was restricted to periods of low aridity and temperature, while photosynthesis continued at a reduced rate during hot, dry conditions. The study, led by a Columbia University carbon cycle scientist, warns that Earth system models linking photosynthesis tightly to growth may overestimate future forest carbon sequestration.
