Leaf-peeping season is underway, but extreme weather and a strong El Niño could impact the vibrancy of fall foliage. While leaves always change color due to reduced sunlight, factors like drought, heavy rain, and heat can alter the timing and intensity of this change. Trees stop photosynthesizing in fall, conserving nutrients by absorbing chlorophyll, which reveals yellow hues. Some trees, like maples, produce red pigments for protection. Climate change can extend growing seasons, leading to less vibrant colors. Different tree species react differently to weather; for instance, sugar maples are sensitive to temperature changes, while oaks are more resilient. Scientists are still exploring how temperature, sunlight, and wildfires affect foliage and what this reveals about tree health and ecosystems.
QUESTION: How might changing climate patterns affect the future of fall foliage and the traditions surrounding it?
