It's taken awhile this fall for the trees to turn colour. Another sign of climate change? Perhaps.
But the sun has begun to shine through the changing leave, giving back some of the light that that the leaves stored during the warm season.
Oh, you say, it doesn't work that way. It's just that the trees have stopped making chlorophyl and the underlying pigments in the leaves are now visible.
Maybe, but you can't deny that trees in their marvelous way have taken the energy from light and used it to make all those leaves, once so brilliantly green and now flashing gold and crimson.
