Largely concentrated where people have disturbed the surface, such damage can be expensive, even heartbreaking. It’s happening now in Fairbanks: Toppled spruce, roller-coaster bike trails, rippled pavement, homes and buildings that sag into ruin. And the meltdown is spreading in wild areas: sinkholes, dying trees, eroding lakes.

These collapses bode ill: They are omens of what scientists fear will happen on a large scale across the Arctic if water and air continue to warm as fast as climate models predict.
