“You might be tempted to say, well that’s a bunch of baloney — global warming,” said Mr. Morse, drilling his first tap holes this season in mid-February, as snow hugged the maples and Vermont braced for a record snowfall. “But the way I feel, we get too much warm. How many winters are we going to go with Decembers turning into short-sleeve weather, before the maple trees say, ‘I don’t like it here any more?’
Seriously, the quote is taken from a New York Times article on how changing seasonal conditions are affecting the sugaring industry, and it doesn't look good:
“It appears to be a rather dire situation for the maple industry in the Northeast if conditions continue to go toward the predictions that have been made for global warming,” said Tim Perkins, director of the Proctor Maple Research Center at the University of Vermont.
“In the ’50s and ’60s, 80 percent of world’s maple syrup came from the U.S., and 20 percent came from Canada,” said Barrett N. Rock, a professor of natural resources at the University of New Hampshire. “Today it’s exactly the opposite. The climate that we used to have here in New England has moved north to the point where it’s now in Quebec.”
And, it's those sugar maples that produce the fall foliage, so global warming could wipe out two of Vermont and Maine's biggest money makers.
