And as winters in the region become more mild, adult deer ticks are becoming more active at a time when they’re normally dormant — causing a bigger public health risk. “It’s becoming a year-round, check-yourself-for-ticks situation,” said Dr. Toni Lyn Morelli with the Northeast Climate Adaptation Science Center.

It’s a revealing paradox of modern life: A place too corrosive for humans to live is the rare place animals can live undisturbed. (Mast, 3/3)
