As the climate crisis melts our ice, our way of life could change in unexpected ways

In Japan, a once-annual Shinto ceremony that revolved around the freezing of a lake is no longer possible most years.

In Minnesota, ice fishing competitions that feed local economies are expected to get cancelled more often as the climate crisis accelerates.

And in Canada, ice roads that serve as a lifeline for isolated Indigenous communities in the North are opening weeks later than they once did.

As our planet warms, the loss of freshwater ice in winter threatens to fundamentally alter our way of life, endangering spiritual practices, cultural traditions and livelihoods, found a study published earlier this year.

“Winters are warming rapidly, and we're already seeing direct changes on the way that we use our environment,” said Sapna Sharma, a co-author of the study and associate professor at York University who studies the impacts of climate change on lakes.

Life in Canada and abroad is intertwined with ice. But the loss of winter could alter our traditions and livelihoods, a new study has found.

“I think there's still a disconnect on what the climate crisis means to us as individuals, what we're losing and how that might affect our well-being.”

The study, published in the October 2019 edition of the journal Limnology and Oceanography, attempted to quantify how the loss of inland ice would affect people, using case studies from across the northern hemisphere.

Much of this work attempted to assign numbers to these impacts: Minnesota’s annual Brainerd Jaycees Ice Fishing Extravaganza brings in an estimated US$1 million per year, for example. And the opening of ice roads in northern Canada have been delayed by as much as three weeks, which tightens the time window within which residents can use the routes for inexpensive travel to see loved ones and get items they need.

But the study also notes that “many human uses related to lake and river ice, such as a loss of sense of place, are more difficult to evaluate empirically and to assign a dollar value.”

Though icy winters are part of Canada’s cultural identity, Sharma said, we have to start thinking about our sense of place in the world will shift along with the climate.

Skating on the Rideau Canal may become rare. And festivals like the Quebec City Winter Carnival may change, too, as the cold months become warmer.

“Tobogganing was a big part of (my generation’s) childhood, and it's something that isn't as common anymore. So even in southwestern Ontario, and in Toronto, we're experiencing this loss of winter,” Sharma said.

“I think it means something different for different people. There's this emotional loss, but this also translates to cultural losses.”

Ice traditions have documented centuries of climate change

In some cases, the researchers found historical records of ice-reliant traditions stretching back centuries before the industrial revolution, when humans began emitting huge amounts of carbon.

The Shinto ceremony was one example, with documentation of ice cover on Lake Suwa, in central Japan, starting in 1443. The archive was updated and maintained by generations of Shinto priests, who documented the formation of an ice ridge that legend says is formed by the footsteps of one god crossing the lake to visit another.

This used to happen nearly every year ⁠— the formation of the ridge was a signal to begin a process to purify minds, bodies and homes. For the first 250 years of record-keeping, there were only three years where Lake Suwa didn’t freeze. But since 1989, the lake has failed to freeze 21 times.

“We have a really long track record that can really tell us about how climate is changing and how rapidly it's changing,” Sharma said.

“(Lake Suwa) is perfect example of a tradition that may be lost in the coming decade,” said Sharma.
