Warmer Fall Leads to Duller Foliage in Ontario

Unseasonably warm temperatures have caused Ontario's fall colors to be less vibrant than usual, experts report.

Ontario experienced higher than normal temperatures in September, particularly impacting the Greater Toronto Area.
Experts indicate that optimal fall colors require a combination of sunny and cold weather, which was lacking this year.
Vibrant foliage typically results from a mix of chlorophyll, carotenoids, and anthocyanins in leaves, influenced by weather conditions.
Climate change is contributing to a trend of warmer falls, potentially leading to less colorful foliage in the future.
Recent cold snaps could still enhance colors in some areas, though the display is expected to be shorter than in previous years.
