In any normal year, north Texas Autumn
leaves develop in late November. During the Autumn of 2006, the leaves
did not change colors at all. One tree which has always had the most
deeply colored leaves in the Fall, failed to change
colors in Autumn 2006. Nor did it drop the leaves. There was no sudden
cold snap... in fact it was warm most of that winter. Nor were there any lack of
water or nutrients. This is very rich farming soil. There was no drought that
year. During Mid-winter, the leaves eventually turned brown, but
still failed to fall from the tree. Only when the trees began to bud in early
February 2007,
did the old leaves finally drop off. While this was odd behavior for
that particular tree, by itself, it would not have been substantial
reason to suspect the angle of the sun was abnormal.
The photos below are mostly Sweet
gum trees which normally develop the most bright orange and red colors every
fall as shown in the first 2 photos. This problem was not limited to just my
trees. It was widespread over this area but I used my trees as an example since
I know their specific normal behavior patterns.
In May, 2007, the trees started
changing to Autumn colors. Within a month, June 07, all of the
sweet gum & oak trees started changing to
Fall colors. (See additional photos below)
This was a substantial
indication that something was wrong. The
trees had gone into photoprotective modes due to the abnormality of the
sunlight they received during these months. This is a significant sign
that the position of the sun has changed.
