Description
As the temperatures dip and the days grow shorter, the trees around us are putting on one of nature’s most spectacular shows — the changing colours of fall. But what exactly triggers those reds, oranges, and yellows, and how are climate change and extreme weather events influencing what we see year to year?

He spoke to Andrew Carter.
