This is the second year the toll ice road has allowed people to bypass a trip to Canada, or a plane or snowmobile ride, to reach the Northwest Angle fishing community resort.

Winter is the fastest-warming season in the Midwest — more than five degrees on average since 1970, according to data from the National Oceanic and Atmospheric Administration.

All that warming is having an impact on ice formation.

“Climate change is injecting more energy into our weather systems, and that’s resulting in in just more extreme extremes,” journalist Kristoffer Tigue told MPR’s Chief Meteorologist Paul Huttner. Tigue wrote about the shift in ice trends for Inside Climate News.

Warmer temperatures could result in a later start for ice formation and a shorter lifespan for lake ice. Add a rapid temperature swing in the middle of winter and the ice can become increasingly unstable.

“On some of the hotter winters, there’s spikes in these fatalities related to falling through the ice,” Tigue said.
