How last year's heat dome helped unleash the clouds of pollen now plaguing Western Canada & More News Here

CBC Alberta and Saskatchewan have teamed up for a brand new pilot sequence on climate and local weather change on the prairies.

If you are a seasonal allergy sufferer, you could have been reaching for the Reactine a bit of greater than regular this yr. 

Pollen has appeared in clouds throughout a lot of Western Canada, piling up on vehicles, decks, driveways and even seashores. 

“It’s ridiculous. I haven’t seen it like this in forever,” says Saige Liimatainen, who’s struggling intense allergy signs this yr the place she lives close to Prince George, B.C.

“I’m sitting in my car right now and I’m looking at a nice layer of pollen on my mirror. And it’s pretty bad. My allergies are pretty awful.”

How unhealthy is it?

Pollen counts have been excessive throughout a lot of Western Canada, in line with Daniel Coates, director of Aerobiology Research Laboratories in Ontario. 

The Ottawa lab screens pollen and spores throughout Canada to offer knowledge and forecasting for a quantity of bushes, together with oak, birch, and pine.

“Right now, pine is actually increasing in Edmonton and it’s been doing that for a little while,” says Coates. 

In Saskatchewan, each Saskatoon and Regina have skilled excessive charges of pollen this spring.

“For pine pollen this year in Saskatoon, it’s similar to last year. We’ve had a couple of days close to 500 grains per cubic metre, which is very high,” he says.

According to Coates, pine in Regina is worse than last yr and has lasted from late May till now.

The root of this floating nuisance is coming from the branches of the coniferous bushes. The flowering show on our bushes is breathtaking — by many definitions, says Janice Cooke, a organic science professor at the University of Alberta.

“The spruce trees in our urban neighbourhoods are just loaded like Christmas trees with all of these cones,” she says. 

“Every so often we get a confluence of developmental circumstances and meteorological circumstances. Everything aligns and we get great flowering and we call that masting.”

This is the first time in a couple of years that we have skilled this, she says.

Heat is a driving issue

Cooke says {that a} tree’s pollen growth operates on a delay. That means this year’s flowering is set by last year’s climate. 

“We had a drought and we also had an extreme heat event last summer. Both those things are really tough on plants,” says Helen Shook, a analysis technician who runs GardenLine,  a free assist service supplied by the University of Saskatchewan.

She says that generally a tree’s response to these circumstances is to enter overdrive the place copy is worried.

“That’s triggering all kinds of things inside the plant. And one of those things is a survival mechanism. So, we’ve got to make babies, we’ve got to make seeds.” 

Cooke says our cooler spring has additionally affected the launch of pollen. She says in a single day frosts and cooler daytime temperatures delayed the pollen shedding.

“They’re all shedding at the same time. And this is why we’re seeing this crazy amount of pollen in the air this year,” says Cooke.

Is local weather change guilty?

The reply to that query is a bit of sophisticated, in line with Cooke. That’s as a result of many of these bushes solely produce massive cone crops sometimes as a result of it takes lots of assets.

“Even under conditions of climate change, where we would maybe see those warm summer temperature heat domes more frequently, they won’t always correspond to these massive crops,” she says.

And although stress on the bushes and excessive cone manufacturing can have an effect on progress, Cooke says it is not dangerous for the bushes to create this a lot pollen. 

“It does put them into a little bit of a deficit going into the season. But this season so far has been really conducive to tree growth,” she says.

Allergy victims are feeling the impacts

Of course, the different factor that’s rising is the irritation of individuals who undergo seasonal allergy symptoms.

Dr. Ross Chang, an allergy specialist in Burnaby, B.C., says sufferers appear to be experiencing extra extreme signs this season over last.

“Allergies are an overreaction of the immune system. We call it hyperreactivity,” says Chang, who was the previous president of the B.C. Society of Allergy and Immunology. “And in certain individuals, otherwise innocuous things like pollen, dust, pets or foods can trigger both moderate or severe allergic reactions.”

Chang says something from itchy, watery eyes and a runny nostril to respiration difficulties like bronchial asthma can all be triggered by pollen counts like what we have been seeing. 

According to Chang, round 20 per cent of individuals in Canada undergo from some type of airborne seasonal allergy.

“The most important thing is that to let people know that there is help for people with allergies, you don’t have to suffer through it,” he says “There’s a lot of methods we can do to help you enjoy your spring and summer activities.”

At the Ottawa pollen lab, Coates concurs that when counts are up there are little issues you are able to do that assist. 

“Go for a walk after it rains because rain washes out the pollen from the air,” he says. 

Even masking up, wraparound sun shades or conserving pets off furnishings on unhealthy pollen days can prevent from signs, in line with Coates.

On actually unhealthy days, drastic measures may apply, he provides.

“Just stay indoors.”
