JEFFERSONVILLE, Vt. — Sitting in his son's sugarhouse, Rex Marsh, 71, can recall winters so cold that no one in northern Vermont ever thought of tapping a sugar maple before town meeting day on the first Tuesday of March.
The winter snow routinely drifted 6 feet deep. Every sluggish step was in snowshoes. Even if the trees thawed, the sap would freeze in the bucket, bursting its metal seams.
"I've been doing this since I was big enough to carry a bucket," Marsh said. "Tapping in January? Never. Never. Never."

While officials argue over carbon emission controls and global warming treaties, tree farmers such as the Marsh family, along with gardeners, anglers and bird-watchers, sense the change in the air.
In response to rising global temperatures, spring comes as much as 13 days earlier in many parts of North America and 15 days earlier in Europe than 30 years ago, scientists say.
