Changes to Canada’s climate now ‘irreversible,’ federal report says

OTTAWA - The impacts of climate change in Canada are now largely irreversible and average temperatures are expected to rise by at least 3.5 C by the end of the century, a new government report warns.

The report, published Thursday, is the second released by Environment and Climate Change Canada examining changes to Canada's climate. It was authored by nearly two dozen government and climate science experts.

It says that even if the world reaches net-zero emissions by 2075 — which would mean any greenhouse gases would be captured by nature or technology — the effects in Canada will be stark.

The report says those effects include a nearly 50 per cent increase in the area burned by wildfires and glaciers in Western Canada losing more than 75 per cent of their mass.

Japanese scientist Shirakawa, co-winner of 2000 Nobel Prize in chemistry, dies at 90

TOKYO (AP) — Japanese scientist Hideki Shirakawa, co-winner of the 2000 Nobel Prize in chemistry for discovering and developing conductive polymers, has died. He was 90.

The discovery by Shirakawa and two fellow American scientists, Alan Heeger and Alan MacDiarmid, demonstrated that plastic could conduct electricity like metal and be used in applications such as electronics.

Shirakawa died on Aug. 24, according to the University of Tsukuba, where he taught and researched after joining in 1979. The university did not specify a cause of death. Japan's largest newspaper, the Yomiuri, said Shirakawa died at a hospital in Yokohama, west of Tokyo.

Born in Tokyo in 1936, Shirakawa earned a doctoral degree in engineering at the Tokyo Institute of Technology in 1966. Ten years later, he became a researcher at the University of Pennsylvania, where he worked with McDiarmid and Heeger.

Recognizing the value of phys-ed for kids

The message from Premier Wab Kinew and Education Minister Tracy Schmidt last week about the importance of exercise for young people was timely and important — but it is not new.

Rare and tough to notice, sarcomas may lurk in the body

Last summer, Michelle Finley was going about a normal day.

She had just dropped her car off at a garage and was walking back to her office building downtown when, suddenly, she was stopped in her tracks by a searing cramp on the bottom of her right foot.

“It was so painful it took my breath away,” says Finley, now 52. “I stopped and held on to the side of a building for a second — like, it was bringing tears to my eyes.”

Finley thought she had a really bad case of plantar fasciitis. Nine months later she would lose her foot to sarcoma.

Beware invasive, ‘frightening’ waterhemp

There’s a threat lurking on the edge of Manitoba farmers’ fields this fall that’s even scarier than the escalating trade war with their biggest customer.

Provincial extension advisers are warning farmers to watch for a weed known as “tall waterhemp,” which, true to its name, may already be towering above ready-to-harvest crops.

Those wispy tentacles waving in the breeze look pretty innocuous from a distance. But this highly invasive member of the pigweed family produces hundreds of thousands of seeds that are just itching for dispersal through farmers’ combines and across their fields.

Each of those tiny seeds — one small pill container filled halfway holds 44,000 — can produce plants with stems the width of saplings and heights of two to five metres. One or two plants can quickly turn into a patch. If waterhemp takes over a field, it can choke out the growing crop and cut yields by more than 90 per cent.

U of M research role expands after $79-M federal injection

The University of Manitoba is playing in a new league.

A $79-million investment will bring five internationally recruited researchers to Manitoba to build “ambitious,” long-term research programs in areas of strategic national importance.

The five researchers will join the U of M thanks to the federal government’s $1.7-billion research talent initiative that’s designed to help Canadian universities compete globally for leading researchers.

The initiative’s flagship program, the Eddie Goldenberg Research Chairs of Canada, provides universities with the funding and resources to recruit world-class researchers, build research teams and pursue large-scale projects in fields considered important to Canada — from Arctic navigation and defence to sustainable mining, health equity and environmental law.

United Nations talks in Mongolia expose growing drought crisis as climate impacts worsen

BENGALURU, India (AP) — Representatives from nearly 200 countries wrapped up United Nations desertification talks in Ulaanbaatar, Mongolia on Friday, seeking ways to keep land productive as climate change heats the planet and degraded soils and landscapes lose their ability to hold water, produce food and support livelihoods.

Up to 40% of the world’s land is degraded, according to the United Nations Convention to Combat Desertification, which organizes the biennial talks. Droughts are also emerging in areas that were not considered highly vulnerable a decade ago, said Yasmine Fouad, the convention’s executive secretary.

“Drought is coming coupled with the impact of climate change,” Fouad said in an interview with the Associated Press. “It’s becoming more frequent, more intense and more prolonged."

Countries left Ulaanbaatar without resolving one of the talks' key issues — whether to create a legally binding global drought agreement — postponing a decision until the next round of talks in Egypt in two years. The issue had already been deferred at the previous meeting two years ago.

Manitoba Hydro’s strategy: Deny, deny, deny

Here’s a good story… A man walks into your office and says, “Have I got a deal for you! I want $3 billion (plus perhaps a bit more) to build you something that you might use three or even four times a year, for maybe 30-60 hours each time. Sign here.”

Researchers tracking Manitoba monarchs migrating to Mexico

Thirty monarch butterflies were outfitted with trackers at the Living Prairie Museum this week as part of a national effort to help preserve the endangered species, marking the first time the new technology has been used in Manitoba.

Smart Suite lets families of children with disabilities learn how adaptive design, tech can improve their lives

The first thing Zoe Versteeg did after rolling into the living room was to change the hue-lighting colour to match the shade of her lavender glasses. The smile that spread across her face was nearly as bright as the lights in the room.

“It’s just joy, immediate joy when she sees something happening. She’s like, ‘I control that, I got to do that,’” Elsien Versteeg, Zoe’s mother, said. “Her being able to make those decisions on her own, she can just do it herself now.”

Zoe, who is 13 and non-verbal, uses eye-gaze technology to communicate and control both her wheelchair and an array of smart devices. Versteeg and Zoe were at the official opening of the Rehabilitation Centre for Children’s new Smart Suite on Aug. 26, where the team behind the project was demonstrating the breadth of adaptive design and technologies available locally for families of children with disabilities to provide them with greater independence.

The Versteegs use many of the devices in their own home near New Bothwell.

Lucky Charms and Trix go au naturel as General Mills ditches artificial colors

General Mills said Wednesday it has removed artificial colors from all its U.S. cereals, including Lucky Charms and Trix.

The Minneapolis company has shifted to fruit- and vegetable-based dyes as well as colors derived from spices like turmeric and paprika to give its cereals their customary bright colors.

“This achievement reflects how we are evolving with consumer needs while continuing to offer food that tastes great, delivers quality and provides value,” said Bethany Quam, General Mills’ president of cereal, in a statement.

General Mills said 90% of its U.S. retail products are now free of artificial dyes. Products that still contain artificial colors, like some Betty Crocker cake mixes and Fruit Roll-Ups, will transition to natural dyes by the end of 2027, the company said.

A bigger grid, and a tougher one

The Free Press editorial of Aug. 21, Time for a stronger Canadian grid, makes a case that should unsettle anyone who read it. A co-ordinated attack on nine substations could bring down the American electrical grid.

City’s landfill gas project hasn’t gained any steam after four years

Four years after the city started working on a proposal to convert potent landfill gases into renewable energy, a lack of buyers is being blamed for holding the project up.

Earth is simmering in its hottest water temps on record, and that’s bad for fish and us

The world's oceans simmered to their hottest temperatures on record over the weekend and are likely to warm even further in the next few months, putting stress on life in the water and on land too, the European climate service Copernicus announced Monday.

Spurred by a still growing but already supersized natural El Nino and human-caused climate change, the world's ocean temperatures hit 21.1 degrees Celsius (70 degrees Fahrenheit) on Friday and Saturday, narrowly edging out the average daily record set in March 2024, said Samantha Burgess, strategic climate lead for Copernicus.

“This is yet another sign of our climate system under strain and the ocean under immense pressure,” Burgess said.

Jane Lubchenco, an oceanographer and former chief of the U.S. National Oceanic and Atmospheric Administration called the record “very troubling.”

Quebecers support a right to cooling during heat waves, poll finds

MONTRÉAL - A new Léger poll has found that three-quarters of Quebecers support recognizing a so-called right to coolness that would guarantee safe places during heat waves.

Overall, 74 per cent of survey respondents said they support the Quebec government recognizing a person's right to living conditions that include temperatures that are considered safe for human health. Sixteen per cent of respondents said they were opposed, while 10 per cent declined to say.

The results also show that 64 per cent of respondents have experienced at least one effect of extreme heat over the past three years.

Those can include headaches, sleep disturbances or breathing difficulties, as well as a need to adjust daily or work activities.

Pretty, purple and pernicious plants plaguing Prairies

After noticing mysterious purple flowers popping up in little patches around the Wolseley neighbourhood last summer, Vic Penner didn’t give it too much thought.

However, this summer, the deceivingly beautiful flowers were impossible to ignore.

“They were just everywhere,” said Penner, 37.

Wolseley isn’t the only neighbourhood being overrun by the plant.

Mobility tests can tell doctors a lot about how you’re aging, but there are many other factors

Hand grip strength. Balance tests. Standing up from a seated position on the floor. These physical challenges are often touted as measurements of healthy aging and even predictors of longevity.

They can provide valuable indications of your stamina and strength. They can estimate the risk of falls, which increase older adults ' risk of death. And they're useful to doctors who work to address aging or people with injuries.

But they're no crystal ball.

“A poor or declining result is a reason for a health professional to investigate why function is changing, rather than gauging how long someone will live,” said Auriel Willette, an expert on brain aging at Rutgers University.

Time for a stronger all-Canadian grid

The New York Times published a quite terrifying story on the U.S. electrical grid this week, one that points out that, with a few simple directed attacks on nine of 10 major U.S. substations, the entire U.S. power grid could be disabled.

Wolseley residents put down roots to save elms

Before-and-after NASA images show crater carved by a SpaceX rocket that slammed into the moon

CAPE CANAVERAL, Fla. (AP) — A NASA spacecraft circling the moon is providing the sharpest views yet of the crater carved by a crashing SpaceX rocket.

The space agency released before-and-after photos of the impact area on Tuesday.

The Falcon rocket’s upper stage plowed into the moon at 5,400 mph (8,700 kph) on Aug. 5 after drifting through space for more than a year. It launched a pair of private moon landers with experiments and even a tiny rover in 2025 as part of NASA’s push to commercialize lunar exploration.

Based on these new photos by NASA’s Lunar Reconnaissance Orbiter, the fresh crater appears to be 60 feet (18 meters) across and less than 10 feet (3 meters) deep, according to scientists.

Trump administration moves ahead to end roadless rule on national forests

ALBUQUERQUE, N.M. (AP) — The Trump administration announced Tuesday it is moving ahead with plans to rescind a quarter-century-old rule that blocked logging, road building and other development on national forest lands, drawing the ire of environmentalists nationwide.

The U.S. Forest Service is filing a proposal that would scrap the so called roadless rule adopted in the last days of Bill Clinton’s presidency in 2001. The agency described the rule as a one-size-fits-all restriction that has frustrated land managers and served as a barrier to reducing wildfire risks in the nation’s forests.

“Our forests can’t afford another decade of inaction. Across the country, we’ve watched preventable conditions — overgrown stands, insect outbreaks and disease — turn healthy landscapes into tinderboxes,” U.S. Agriculture Secretary Brooke Rollins said in a statement.

Scientists say that worsening wildfires are driven by a combination of climate change that warms and dries out forests, less logging and decades of fire suppression that has allowed fuels to build up.
