All Tapped Out

The Daily Climate writes All tapped out. It has lots of details of where maple syrup comes from and a big warning.

"According to research from Barry Rock, professor of natural resources at the University of New Hampshire, the New England region, including upstate New York, has already warmed an average of 0.7˚ F over the last century, with the bulk of that warming in the winter — an average gain of 1.8˚ F. That warming has already had an impact: This year some sugarmakers in New Hampshire were unable to make any Grade A syrup."

"It is the 3˚ to 10˚ F warming predicted over the next century by the United Nations Intergovernmental Panel on Climate Change that may doom the sugar maple in the northeastern U.S. Even the U.S. Environmental Protection Agency concedes that the sugar maple will not survive the century in New England. Its Climate Action Report from 2002 notes "climate change is likely to cause long-term shifts in forest species, such as sugar maples moving north out of the country." In other words, it is not a question of if the sugar maple will disappear, it is a question of when."
