“By the twenty-fifth of September, the Red Maples generally are beginning to be ripe,” Henry David Thoreau wrote in his 1862 essay “Autumnal Tints. “Some large ones have been conspicuously changing for a week, and some single trees are now very brilliant.” He goes on to say that sugar maples, whose change generally follows red maples, “are most brilliant” about the second of October. But if you’ve been to New England lately, you know that most trees, including the maples, are still bottle green on those dates. And if you’ve been north, to Nova Scotia, you know that by October the hills are still as nubbly with color as an aunt’s embroidered pillow. A century ago, the flaming fall #foliage of that Canadian province would have long faded by now. What’s going on? #Climatechange, scientists say. As the seasonal change creeps later into the year, the glorious colors will last longer across the Canada and the United States— a rare instance where global warming is giving us something to look forward to. On October 12, @ianwillms photographed #fallcolors beginning to show in Cape Breton, Nova Scotia.
