Blog Post Image: Fall foliage season may be later, but longer on warmer Earth

The researchers also found that the timing of leaf change is more sensitive to temperature in warmer areas than in colder regions — the more southern the region, the more likely there is to be a delay in leaf coloration. In addition, the nearly 20 species the study reviewed respond differently to the sustained summer conditions projected to occur with climate change. For instance, the particularly sensitive paper birch could change color one to three weeks later by the end of the century, the researchers found.
