What will this cold snap mean for our bugs?

Published

The Prairies Climate Change Project is a joint initiative between CBC Edmonton and CBC Saskatchewan that focuses on weather and our changing climate. Meteorologist Christy Climenhaga brings her expert voice to the conversation to help explain weather phenomena and climate change and how they impact everyday life.


The last few weeks have felt like an early welcome to spring. Thawing temperatures began to eat away at the snowpack in Alberta during the first few weeks of February.

But this winter has another trick up its sleeve. A deep freeze moving into the province this week will drive the mercury down to the minus 20s or even minus 30s.

“The cold air is very close now and we’re going to see temperatures well below normal to finish this month,” said Kyle Fougere, meteorologist with Environment and Climate Change Canada.

While many of us can reach back into the closet for our parkas, plants and animals are not quite as lucky. What will this late and abrupt cold snap mean for insects that are weathering the winter?

Winter cold and wild things

During the winter, some insects will burrow deep into the ground, waiting for warmer weather. Some remain awake.

“Our wolf spiders, springtails — a bunch of different things are actually active under the snow and we just can’t see them,” said Peter Heule, live animal supervisor at the Royal Alberta Museum.

Invertebrates survive by producing a kind of antifreeze or a cryoprotectant in their bodies.

“Antifreeze is going to mean that your body tissues will remain liquid even when we’re below zero. And then the cryoprotectants basically allow ice crystals to form in your body, but not in places where they’re going to cause damage,” he said.

Even with those adaptations, insects also need a layer of insulation, seeking refuge just under the snow or leaf litter of a yard.

A winter marked by wild swings

We know that bugs are impacted by cycles of thawing and sudden deep freezes. And there has been no shortage of either this winter, with temperatures that spent very little time around the “normal” mark.

A warm autumn hit a U-turn in December with a deep freeze pulling temperatures into the minus 30s.

“It was actually very cold in December for Alberta and especially those first three weeks,” said Fougere.

As the calendar switched over to 2023, the weather also flipped, with warmer southern air and cloudy conditions helping to insulate the province.

“From about the 25th, 26th of December, we had a full, one-month period where it was near normal or slightly above normal for Alberta,” said Fougere.

“This milder trend has continued for the first couple of weeks of February.”

That luck had to run out eventually. This week, cold Arctic air will push into Western Canada.

“For the next couple of weeks, we’re not sure exactly where the coldest air is going to be,” Fougere said, “but it’s likely that we’re going to see Arctic air spread over the Prairies and indications are that it could be longer lived.”

And this particular cold snap is expected to have some staying power with frigid conditions looking to last out the month and forecasts calling for a cooler-than-normal spring.

“It’s pretty common this time of year to have these pretty large swings in the weather,” said Fougere.

The promise of spring

When winter includes wild swings in temperature, we can see higher mortality rates in the insect populations. The full impact of this winter’s fluctuations won’t be known until spring.

“Sometimes overwintering or hibernating is a risky business,” said Heule. “If you don’t choose the right site, you might not make it all the way through.”

Heule said that insects like pupating caterpillars that turn into moths and butterflies may come out early in long warm stretches and perish as they are unable to find host plants, but others can adapt.

“Wolf spiders might come out of the leaf litter and scurry around. And then as those temperatures start to drop, they might be able to find their way back to some other sheltered site or the original place they were hiding out,” he said.

“But you certainly wonder how many of these things are going to be able to find their way back to shelter or maybe get stuck in those cold temperatures.”

And as for the bugs you want to see in your yard to help your native plants thrive, Heule said there are ways to protect those insects from winter variability, such as melting snow.

“I put all of the leaf litter and all the fallen leaves into my garden beds to sort of act as a more reliable blanket than the snow and I find a lot of [insects are] using that insulation.”

Bad traffic, changed plans: Toronto braces for uncertainty of its Taylor Swift Era

Published

 on

TORONTO – Will Taylor Swift bring chaos or do we all need to calm down?

It’s a question many Torontonians are asking this week as the city braces for the arrival of Swifties, the massive fan base of one of the world’s biggest pop stars.

Hundreds of thousands are expected to descend on the downtown core for the singer’s six concerts which kick off Thursday at the Rogers Centre and run until Nov. 23.

And while their arrival will be a boon to tourism dollars — the city estimates more than $282 million in economic impact — some worry it could worsen Toronto’s gridlock by clogging streets that already come to a standstill during rush hour.

Swift’s shows are set to collide with sports events at the nearby Scotiabank Arena, including a Raptors game on Friday and a Leafs game on Saturday.

Some residents and local businesses have already adjusted their plans to avoid the area and its planned road closures.

Aahil Dayani says he and some friends intended to throw a birthday bash for one of their pals until they realized it would overlap with the concerts.

“Something as simple as getting together and having dinner is now thrown out the window,” he said.

Dayani says the group rescheduled the gathering for after Swift leaves town. In the meantime, he plans to hunker down at his Toronto residence.

“Her coming into town has kind of changed up my social life,” he added.

“We’re pretty much just not doing anything.”

Max Sinclair, chief executive and founder of A.I. technology firm Ecomtent, suggested his employees avoid the company’s downtown offices on concert days, saying he doesn’t see the point in forcing people to endure potential traffic jams.

“It’s going to be less productive for us, and it’s going to be just a pain for everyone, so it’s easier to avoid it,” Sinclair said.

“We’re a hybrid company, so we can be flexible. It just makes sense.”

Swift’s concerts are the latest pop culture moment to draw attention to Toronto’s notoriously disastrous daily commute.

In June, One Direction singer Niall Horan uploaded a social media video of himself walking through traffic to reach the venue for his concert.

“Traffic’s too bad in Toronto, so we’re walking to the venue,” he wrote in the post.

Toronto Transit Commission spokesperson Stuart Green says the public agency has been working for more than a year on plans to ease the pressure of so many Swifties in one confined area.

“We are preparing for something that would be akin to maybe the Beatles coming in the ‘60s,” he said.

Dozens of buses and streetcars have been added to transit routes around the stadium, and the TTC has consulted the city on potential emergency scenarios.

Green will be part of a command centre operated by the City of Toronto and staffed by Toronto police leaders, emergency services and others who have handled massive gatherings including the Raptors’ NBA championship parade in 2019.

“There may be some who will say we’re over-preparing, and that’s fair,” Green said.

“But we know based on what’s happened in other places, better to be over-prepared than under-prepared.”

Metrolinx, the agency for Ontario’s GO Transit system, has also added extra trips and extended hours in some regions to accommodate fans looking to travel home.

A day before Swift’s first performance, the city began clearing out tents belonging to homeless people near the venue. The city said two people were offered space in a shelter.

“As the area around Rogers Centre is expected to receive a high volume of foot traffic in the coming days, this area has been prioritized for outreach work to ensure the safety of individuals in encampments, other residents, businesses and visitors — as is standard for large-scale events,” city spokesperson Russell Baker said in a statement.

Homeless advocate Diana Chan McNally questioned whether money and optics were behind the measure.

“People (in the area) are already in close proximity to concerts, sports games, and other events that generate massive amounts of traffic — that’s nothing new,” she said in a statement.

“If people were offered and willingly accepted a shelter space, free of coercion, I support that fully — that’s how it should happen.”

‘It’s literally incredible’: Swifties line up for merch ahead of Toronto concerts

Published

 on

TORONTO – Hundreds of Taylor Swift fans lined up outside the gates of Toronto’s Rogers Centre Wednesday, with hopes of snagging some of the pop star’s merchandise on the eve of the first of her six sold-out shows in the city.

Swift is slated to perform at the venue from Thursday to Saturday, and the following week from Nov. 21 to Nov. 23, with concert merchandise available for sale on some non-show days.

Swifties were all smiles as they left the merch shop, their arms full of sweaters and posters bearing pictures of the star and her Eras Tour logo.

Among them was Zoe Haronitis, 22, who said she waited in line for about two hours to get $300 worth of merchandise, including some apparel for her friends.

Haronitis endured the autumn cold and the hefty price tag even though she hasn’t secured a concert ticket. She said she’s hunting down a resale ticket and plans to spend up to $600.

“I haven’t really budgeted anything,” Haronitis said. “I don’t care how much money I spent. That was kind of my mindset.”

The megastar’s merchandise costs up to $115 for a sweater, and $30 for tote bags and other accessories.

Rachel Renwick, 28, also waited a couple of hours in line for merchandise, but only spent about $70 after learning that a coveted blue sweater and a crewneck had been snatched up by other eager fans before she got to the shop. She had been prepared to spend much more, she said.

“The two prized items sold out. I think a lot more damage would have been done,” Renwick said, adding she’s still determined to buy a sweater at a later date.

Renwick estimated she’s spent about $500 in total on “all-things Eras Tour,” including her concert outfit and merchandise.

The long queue for Swift merch is just a snapshot of what the city will see in the coming days. It’s estimated that up to 500,000 visitors from outside Toronto will be in town during the concert period.

Tens of thousands more are also expected to attend Taylgate’24, an unofficial Swiftie fan event scheduled to be held at the nearby Metro Toronto Convention Centre.

Meanwhile, Destination Toronto has said it anticipates the economic impact of the Eras Tour could grow to $282 million as the money continues to circulate.

But for fans like Haronitis, the experience in Toronto comes down to the Swiftie community. Knowing that Swift is going to be in the city for six shows and seeing hundreds gather just for merchandise is “awesome,” she said.

Even though Haronitis hasn’t officially bought her ticket yet, she said she’s excited to see the megastar.

“It’s literally incredible.”

Via Rail seeks judicial review on CN’s speed restrictions

Published

 on

OTTAWA – Via Rail is asking for a judicial review on the reasons why Canadian National Railway Co. has imposed speed restrictions on its new passenger trains.

The Crown corporation says it is seeking the review from the Federal Court after many attempts at dialogue with the company did not yield valid reasoning for the change.

It says the restrictions imposed last month are causing daily delays on Via Rail’s Québec City-Windsor corridor, affecting thousands of passengers and damaging Via Rail’s reputation with travellers.

CN says in a statement that it imposed the restrictions at rail crossings given the industry’s experience and known risks associated with similar trains.

The company says Via has asked the courts to weigh in even though Via has agreed to buy the equipment needed to permanently fix the issues.

Via said in October that no incidents at level crossings have been reported in the two years since it put 16 Siemens Venture trains into operation.
