No Maple Syrup by 2100?
A few years ago, Martha Carlson, a veteran maple farmer, began noticing subtle changes in her 60-acre "sugar bush" in Sandwich, New Hampshire: Maple sap was unusually dark, and leaves were falling too early, never having reached postcard New England color. Her sugar maples, some of them nearly 300 years old, were sick.
At 65, Martha now leads the crusade to save the New Hampshire sugar maples—and the multimillion dollar local syrup and tourism industries they provide—from disastrous climate change. And in the process she's mobilizing a crack team of researchers: a group of elementary school kids.
