Thetford naturalist Ted Levin has kept field journals since he moved to the Upper Valley. Recently he published a story in the Boston Globe Magazine based on 40 years of these field notes. While some may deny that the climate is changing, no one can argue that seasonal norms in the Upper Valley have not changed during our lifetimes. Sugaring season begins earlier and Fall frosts come later. Black flies hatch sooner and turkey vultures stick around longer.
"In the 40 years since I moved to Vermont, I have kept a journal noting (among other things) phenology, the science of seasonal natural phenomena. Over those decades, the seasons that give definition to our lives in New England have changed — often in small, almost imperceptible increments, like watching a child grow, until suddenly you can no longer deny the alterations," writes Levin in his Globe story.
