I do see something right now. The grass in my front yard is still bright green. In December. In Michigan.
Twenty years ago, the grass had all turned brown and had gone dormant by the first or second week of November. Now it doesn't happen until the middle of December.
Not just this year, but every year. Every year the grass stays greener just a bit longer.
Say what you want, think what you want, but my grass is still green in December.
Not what I'd call a "dire effect."
Your grass may be staying green longer and that may be due to some global climate change or to some regional climate change.
I recall when hurricanes took down most of the large, old willow trees in my then area of NYC. That was in the 1950s and 1960s. Hasn't recurred. And that obviously hadn't occurred for some time prior to that period for the fact of the trees being old. Change happens.
