Time - There’s no one-size-fits-all answer for how climate change is impacting the natural phenomenon. Impacts vary depending on the type of tree and the region it lives in.
One thing’s for certain, which is that the color change that we see in the autumn is caused by a chemical process—and that isn’t likely to be impacted by climate change....
However, trees need cold temperatures to produce the vibrant hues we’re used to seeing. If the leaves in your area are a disappointing brown, it could be that the temperatures didn’t drop low enough to produce bright colors...
Rain and drought can also impact the leaves, with too much leading to fungus and too little leading to “drought scorch.” ... After a summer of drought and erratic rainfall, experts predict that New England’s famous fall foliage, which brings an estimated $8 billion to local economies, will be “bright, brief and early” this year.
