The library in Palmer partially collapsed on Wednesday evening near closing time.

Six weeks after a series of snowstorms dumped more than three feet of snow, bus stops along a handful of state-maintained roads remain buried, forcing transit users to navigate deep, slippery drifts and towers of snow.

Denali receives a foot of snow in mid-winter storm. Interior areas, including Fairbanks, also received high amounts of snow.

Climatologist Rick Thoman says climate change is driving this more extreme winter snowfall. As the oceans warm, more moisture evaporates into the air. Then, when the atmospheric conditions are right for a storm, that increased evaporation results in “heavier and heavier precipitation,” Thoman said. That’s in part why Anchorage saw 41.2 inches of snow last month, capping off its wettest year on record, according to the National Weather Service.
