Well, there's definitely something going on with the climate. We're one week from Halloween, and I've barely had any leaves fall. I distinctly remember a season 7 years ago (memorable for some reasons) where a couple days before Halloween, I was doing my second leaf pick up already and thinking that I have one more round left before all the leaves were down. Last year a lot of the leaves never fell and stayed on the trees. And this year, so far, a week off until November, barely 15-20% of the leaves have changed colors, and only a small percentage of those have fallen. At this rate, I'll be picking up and cleaning leaves on Thanksgiving ... assuming it isn't snowing by then. For about the past 5-6 years, we've had green Christmas. Last year I only had to pull out the snow shovel TWICE all Winter, whereas 5-6 years ago, I had to do a daily cleanup.
Whether these changes are being engineered or else natural, I don't know, but there are definite changes.
