Scientists have been looking at pollution affecting the air, land and water around the Athabaska Oil Sands for some time. After looking at contaminants in snow taken from up-to 25 km away from the oil sands, a McGill-led scientific team now suggests that oil sand pollution is also affecting the weather patterns in the surrounding regions.

"The beauty of frozen precipitation such as snow is that it's like a snapshot of atmospheric processes. The snow absorbs the hard metal particles and embeds it and this allows us to see things that we might not be able to see otherwise," says Professor Parisa Ariya, from McGill's Departments of Chemistry and Atmospheric and Oceanic Sciences. She led the team that recently published their research in Environmental Pollution.

More specifically, the researchers looked at the presence of nanosized particles of metal contaminants in order to gain insight into the larger weather patterns. They discovered:

    That the presence of nanosized particles of metal contaminants (such as chromium, nickel, copper) is much higher (100 times more) than in snow taken from the middle of a Canadian city (Montreal), indicating that air pollution is much greater close to the oil sands
    That the structure of the contaminants in the nanoparticles and microparticles allows a process called ice nucleation -- which is at the heart of cloud formation -- to take place more rapidly and efficiently and at higher temperatures than when there is simply mineral dust in the air. This means that they can alter cloud formation processes as well as precipitation frequency and intensity, which control extreme weather events, such as floods and droughts at the two extremes.

These results are of concern since both the World Health Organization (WHO) and the International Panel on Climate Change (IPCC) have identified nanoparticle pollution as a major challenge in climate change. Further research is being done in Professor Ariya's lab to explore the effects of other major industrial pollutants.

Stray dog found cuddling orphaned kittens on freezing night in Ontario

theweathernetwork.com

Saturday, November 23rd 2019, 4:37 pm - This incident has reminded many that winter weather calls for additional precautions when it comes to taking pets outdoors.

Many are calling this stray dog a hero after it was found cuddling five orphaned kittens that were stuck in the snow during a chilly night in Chatham-Kent, Ontario.

The animals were found in the cold last weekend by a passerby who then brought the animals to the Pet and Wildlife Rescue shelter.

The shelter shared a photo of the animals safely indoors and added the caption, “Our stray sweetheart is keeping her ‘babies’ safe at the shelter tonight!”

Last weekend there was a light layer of snow on the ground and temperatures were around -4°C with the wind chill dipping into the minus teens.

While certain animals and breeds can handle a variety of winter conditions, the frigid weather was dangerous for the newborn kittens.

This incident has reminded many that winter weather calls for additional precautions when it comes to taking pets outdoors.

Dr. Gary Landsberg, a veterinarian behaviourist who has been practicing for more than 30 years, told The Weather Network that the dangerous weather threshold for outdoor play is around -10°C to -15°C, no matter what kind of breed you have.

Although certain sled dogs can remain outside for hours, not all dogs fare as well in the snow. "Breeds with short hair, smaller breeds and breeds that aren't used to spending time outside are usually more susceptible to the cold conditions," he says.

Ontario: Messy mid-week system takes aim, eyes on a wintry weekend blast
Digital Writers
theweathernetwork.com

Monday, November 25th 2019, 7:30 am - While Monday starts on a mostly pleasant, milder note, unsettled conditions will move into the region by mid-week with eyes on a winter-like weekend system as well.

The week opens on a quieter note for southern Ontario, though it won't be without its showers as a weak clipper slides through the Great Lakes region. The next major weather-maker takes aim on the area through mid-week, where forecasters are watching for a developing Colorado low set to bring rain, snow, and a wintry mix to parts of the region. More on the timing of when this system intensifies, plus a look at a winter-like storm that threatens southern Ontario this weekend, below.

Visit our Complete Guide to Winter 2019/2020 for an in-depth look at the Winter Forecast, tips to plan for it and a sneak peek at the spring season next year
WEATHER HIGHLIGHTS:

    Colorado low takes aim on region for mid-week
    Rain, snow, and wintry mix all expected across province; mainly snow in north and rain in south
    Cold pattern locks in for early December
    Stay up-to-date on the ALERTS in your area

WATCH BELOW: EYES ON NEXT CLASSIC FALL STORM

High pressure edging into the Great Lakes for Monday will make for a generally quiet start to the new workweek across southern Ontario. An Alberta clipper will bring scattered showers to cottage country and eastern Ontario through early Tuesday, with some heavier snow expected in the north.

ONSnow1 (1)
MORE WIDESPREAD IMPACT BY WEDNESDAY WITH A COLORADO LOW

Forecasters are closely watching a Colorado low expected to take aim on Ontario by Wednesday -- one that will have more widespread impacts on the province.

While the system won't develop until early Tuesday, initial computer model guidance suggests the storm will bring strong winds and bouts of heavy rain and snow into the Great Lakes region through Wednesday. This will make for a messy mid-week across much of the province. For those east of Lake Superior and across the Nickel Belt, as much as 30 cm of snow is possible with major impact to travel expected.

Unprecedented weather bomb will have impacts for much of Canada
Caroline Floyd
Meteorologist

Tuesday, November 26th 2019, 5:00 pm - This record-breaker will have impacts here at home.

The so-called bomb cyclone is a fact of life along the east coast. These rapidly-developing storms are infamous for bringing Atlantic Canada some of the worst weather fall and winter have to offer, with heavy snow and lashing winds. When flow from the warm Gulf Stream and cold air flooding down from northern Quebec and Hudson Bay collide, a vigorous nor'easter is often the result. The Eastern Seaboard is perfectly arranged to support these kinds of explosive systems, dubbed 'weather bombs' when the central pressure lowers by at least 24 millibars in 24 hours.

So the weather bomb that's developed off the coast of Oregon and California has forecasters across North America sitting up and taking notice.

Atlantic: Significant snow for some as potent system tracks in
Digital Writers
theweathernetwork.com

Wednesday, November 27th 2019, 8:00 pm - A Colorado low will bring snow to parts of Atlantic Canada this week.

A major Colorado low is set to cruise into Atlantic Canada through the second half of the week, and it's on a track to bring snow to spots that have avoided it so far this fall. Blustery northwest winds behind the system will also usher in brisk wind chill values and onshore snow for the weekend, as well. We take at the timing of this stormy and wintry set-up, below.

Ontario: Travel impact expected with heavy snow, ice Sunday
Digital Writers
theweathernetwork.com

Friday, November 29th 2019, 9:10 am - December arrives on Sunday and so does the wrath of winter in southern Ontario. Plan ahead.

As the week ends on a much calmer -- and much colder -- note across southern Ontario, forecasters are closely watching the next Colorado low that threatens the region with rain, snow and ice to kick off the month of December. "This will be a messy and high impact wintry system for much of southern and central Ontario, including across the Greater Toronto Area, where major impact on travel is expected," says Weather Network meteorologist Dr. Doug Gillham. More on the timing of this system and who stands to see 10+ cm of snow, below.

Saturday, November 30th 2019, 8:02 am - December arrives on Sunday and so does the wrath of winter in southern Ontario. Plan ahead.

The (comparatively) warmer temperatures earlier in the week are a fond memory, with Saturday another cool day for Ontario. It will be calm, certainly, but the start of December on Sunday will be marked by the effects of a Colorado low that threatens the region with rain, snow and ice. For a closer look at when it starts, and who should expect the worst, read on.

WEATHER HIGHLIGHTS:

    Low-pressure system will bring freezing rain, ice pellets and snow late Saturday night and into Sunday
    Colder patterns looks to arrive during the second week of December
    Stay up-to-date on the ALERTS in your area

WATCH: TIMING OF FREEZING RAIN, ICE PELLETS AND SNOW

Below seasonal temperatures will be widespread across southern Ontario on Saturday due to a departing Colorado low. Despite being chilly, conditions will remain calm into the afternoon, making for the best travel day of the weekend by far.

That's ahead of the new Colorado low that will track towards southern Ontario region Saturday night, which threatens a widespread messy and wintry mix. All forms of precipitation are possible; snow, ice pellets, freezing rain, and rain.

Ontario: Hwy. 401 re-opens near Kingston after major, deadly pileup
Digital Writers
theweathernetwork.com

Monday, December 2nd 2019, 7:45 am - Travel was treacherous across southern Ontario on Sunday amid widespread freezing rain, ice pellets, and heavy snow.

Freezing rain warnings wound down across southwestern Ontario Sunday afternoon. Still, the damage had already been done after 10+ hours of icy precipitation left a thick glaze over much of the region and made for dangerous travel conditions. Farther east, snowfall warnings lingered into the evening along the eastern end of Lake Ontario, where a massive pileup closed Highway 401 and left at least one person dead

Ontario Provincial Police said the wreck happened around 2:30 p.m. near Kingston, amid heavy snow. In a statement to CBC News, Kingston General Hospital reported 15 to 20 people had been transported to the hospital, "most of whom have non-life-threatening injuries." Police also raised their initial estimate on the number of vehicles involved, saying as many as 30 to 40 were caught in the wreck.

The OPP has confirmed at least one person died in the pileup. Local media reported police were moving stranded travellers off the highway using Kingston Transit buses. The highway re-opened by about 4:30 on Monday morning after being closed for much of the night on Sunday, with the cause of Sunday's crash under investigation.

How this new weather radar in Exeter will mean better tracking of dangerous storms

Social Sharing

The new radar is part of a nation-wide upgrade that will cost more than $100 million

Viewed from across a frozen field, the new weather radar tower near Exeter, Ont., looks like a massive golf ball fused to a pillar of iron five storeys tall.

    Federal government buying new radar system to better detect severe weather

And though the site on Thames Road looks similar to the one it replaced in August, Environment Canada meteorologist Gerald Cheng says it comes with significant upgrades. The new equipment will mean more accurate and up-to-the minute forecasts for everyone who lives inside a coverage blanket that extends from Windsor to the Bruce Peninsula to the Niagara region.

"It's certainly a tool that's well worth the investment," said Cheng Tuesday.

And it's quite an investment.

The Exeter site cost $4 million and is part of a $107-million plan by the federal government to upgrade its coast-to-coast network of 31 other weather radar sites.

Each radar site feeds up-to-the-minute data to Environment Canada's weather radar website and its many clients.

Cheng says the Exeter tower has life-saving potential in southwestern Ontario, a region known for sweltering summers that bring thunderstorms — and the occasional tornado —  and frequent snow dumps over the long, icy winter.

The upgrades of the new system include:

    More frequent data uploads The new system sends data every six minutes; the last one reported at 10-minute intervals. "That's important in terms of lead time when issuing warnings," said Cheng.
     
    Longer range  The older radar sites had a radius of 120 kilometres, the new ones are double that. The signal is also stronger and able to penetrate patches of heavy rain much better than the previous system.
     
    Fewer shut downs for maintenance  Cheng said the new system only needs two maintenance shut downs per year under regular conditions. The older sites required six.
     
    Dual polarization  We're wading into weather nerd territory here, but, essentially, this means more detailed weather data because it sends signal waves in two orientations, both vertical and horizontal. "It's able to tell us the shape of precipitation that's falling," said Cheng. "So it's able to distinguish between a snowflake, versus rain drops, versus hail. That is tremendous for us."

Climate change to push food prices higher, nearly $500 for Canadian families: report


The Canadian Press
Staff

Contact
Published Wednesday, December 4, 2019 9:58AM PST Last Updated Wednesday, December 4, 2019 7:29PM PST

VANCOUVER -- The average Canadian family will pay up to an extra $487 on feeding themselves next year, according to an annual food price report that highlights climate change as a major culprit for rising food prices, especially in the produce department.

Unexpected snowstorms, droughts and other weather events have impacted crops and food prices in the past, said Simon Somogyi, lead researcher from the University of Guelph.

But for 2020, he and others behind the report highlight climate change as the cause.

“We're deliberately pointing out that, you know: climate change is causing the droughts, is causing the bad snowstorms that's impacting prices,” he said.

The report calls the impact of changing weather patterns on our food systems through droughts, forest fires, heavy precipitation, reduced freshwater access and rising sea levels “the elephant in the room” for 2020.

“Canadian farmers will face challenges in the future dealing with unpredictable crop yields, heat-wave livestock threats, pasture availability, and pest and disease outbreaks,” reads the report from researchers at Dalhousie University and the University of Guelph.

That link between climate change and food prices comes along with a forecast that the average Canadian family will spend $12,667 on food at grocery stores and restaurants in 2020.

That's two to four per cent more than in 2019 - thought the researchers expect it to be closer to the top end of that range. It's the second-highest prediction since 2013. It's outdone only by an anticipated three to five per cent, or $420, rise for the year 2017. The algorithm provides a two-per cent range for the national forecast.

The expected rise in food prices comes as Canadians face relatively steady inflation. The consumer price index rose 1.9 per cent year-over-year in October, according to Statistics Canada - the same increase as the previous two months. Increases have remained below 2.5 per cent since Sept. 2018.

Next year, researchers expect price increases in all eight food categories they track with the biggest jump - four to six per cent - in meat.

Pork prices will likely lead that ascent due to the African Swine Fever outbreak in China roiling pork markets.

Food sold at restaurants, as well as seafood and vegetables, will likely see the next biggest price increases in 2020. The report estimates a jump of two to four per cent in those three categories. The estimated rise in vegetable prices comes after a staggering 12 per cent increase for the 12 months ended Sept. 2019. Much of that double-digit jump Somogyi attributes to climate change.

Storms and other weather events wreak havoc on logistics, he said. They can slow down transportation, for example, and create a shortage that results in higher prices.

A hotter climate is one factor behind an increase in bacterial outbreaks such as E. coli, Somogyi said, as hotter temperatures and unpredictable heat waves increase bacterial growth. In recent years, multiple E. coli outbreaks prompted grocers to pull romaine lettuce off their shelves and restaurants to stop serving the leafy green. That tends to drive up prices for alternatives, like spinach.

Produce prices also trend up because Canada imports vast amounts of its food as the colder weather in the country limits what can be grown. Imported goods can fluctuate in price due to trade issues
