Records shattered as summer heat hits Southwest in March; ‘This is what climate change looks like’

WASHINGTON (AP) — The dangerous heat wave shattering March records all over the U.S. Southwest is more than just another extreme weather blip. It’s the latest next-level weather wildness that is occurring ever more frequently as Earth’s warming builds.

Experts said unprecedented and deadly weather extremes that sometimes strike at abnormal times and in unusual places are putting more people in danger. For example, the Southwest is used to coping with deadly heat, but not months ahead of schedule, including a 112 degrees Fahrenheit (44.4 degrees Celsius) reading in two Arizona communities on Friday that smashed the highest March temperature recorded in the U.S. Two places in Southern California also hit that same temperature. All four spots are clustered within about 50 miles (80.5 kilometers) of each other.

“This is what climate change looks like in real time: extremes pushing beyond the bounds we once thought possible,” said University of Victoria climate scientist Andrew Weaver. “What used to be unprecedented events are now recurring features of a warming world.”

March's heat would have been virtually impossible without human-caused climate change, according to a report Friday by World Weather Attribution, an international group of scientists who study the causes of extreme weather events.

Winnipeg and ground squirrels

In a move shocking to many local animal lovers, the City of Winnipeg has opted to go ahead with its plan to kill ground squirrels at nine city parks and fields via methods that animal advocates say will cause prolonged pain and suffering.

Meteorite hunters scour Ohio for fragments of 7-ton space rock that crashed into Earth

MEDINA, Ohio (AP) — Meteorite hunters fanned out across a wide swath of Ohio on Thursday, hoping to collect fragments of an estimated 7-ton (6,350 kilograms) space rock that crashed into Earth this week after a dazzling fireball that was seen from hundreds of miles away.

The meteoroid broke apart around 9 a.m. Tuesday over Valley City, a half-hour south of Cleveland, after it sped through the atmosphere at about 45,000 miles (72,420 kilometers) per hour. It caused a sonic boom that rattled buildings and caused fears of an explosion. The fireball was seen from Wisconsin to Maryland, and NASA confirmed it was a meteoroid nearly 6 feet (1.8 meters) in diameter.

Medina resident December Harris didn’t have to go looking — her cousin and roommate, Ambra Sinclair, found a small black rock they suspect is a meteorite when she was leaving for work. They had heard the sonic boom Tuesday morning but figured it might have been noise from a nearby airport.

Harris said her roommate found the rock in a 4-foot (1.2-meter) area between the garage and the house late Wednesday morning. She described it as somewhat triangular shaped, less than 2 inches (5 centimeters) in diameter — and “very, very black,” with pits on the surface, grooves and a melted texture on its exterior.

Unusual atmospheric river will impact B.C. for days, even after it ends, says expert

VANCOUVER - Emergency officials say residents stranded by an early morning mudslide in Coquitlam, B.C., on Thursday have been safely extracted by helicopter, but a meteorologist warns such slides remain a possibility as an atmospheric river continues to drench the province.

RCMP say they were called to a rural area near the Upper Coquitlam River just after 5:30 a.m. following reports of a mudslide north of the Upper Coquitlam River Park. Coquitlam Search and Rescue said in a social media post that its crews started to rescue residents, who were stranded on the north end of Pipeline Road, just before 10 a.m.

The post said all eight residents, two dogs and one cat living in the area were extracted by a helicopter by 2:45 p.m.

BC Hydro said the slide knocked down a power line, temporarily leaving some 5,000 people without power. The utility expected power to be restored to all affected customers late Thursday or early Friday, but noted crews were having difficulty accessing the damage due to the unstable ground.

David Suzuki is turning 90. Environmentalists may have ‘lost, big time,’ but he still has hope

David Suzuki admits defeat — at least in some respects.

The geneticist-turned-environmentalist, who is days away from his 90th birthday, reflected on his legacy as he prepared to release his latest book, "Lessons from a Lifetime," which compiles photos and stories from his life, as well as testimonials written by those he inspired.

"To me, the important legacy that I want to tell my grandchildren is, look, I tried. I love you. I did the best I could for you. And I tried," he said on a video call last month.

"The measure of a person is not whether they succeeded — because we've lost, environmentalists have lost, big time — but that we tried."

Churchill port could further stunt polar bear growth: U of M researcher

Manitoba’s bold plan to transform the Port of Churchill into a shipping powerhouse could have a negative effect on the area’s treasured polar bear population, which fuels its tourism trade, new research shows.

Oldest known whale recording could unlock mysteries of the ocean

A haunting whale song discovered on decades-old audio equipment could open up a new understanding of how the huge animals communicate, according to researchers who say it’s the oldest such recording known.

Speed limits and safety — follow the science

The premier of Manitoba recently appeared hesitant about collaborating with Winnipeg City Council on a public works proposal to lower the city’s default residential speed limit from 50 km/h to 40 km/h. Without a provincial amendment to the Highway Traffic Act, the city says implementing the change would require installing signs on hundreds of streets, at a cost of up to $10 million to taxpayers.

Years of training keep Artemis II crew mission-ready, researcher says

MONTREAL - Despite the delays for NASA's Artemis II mission around the moon and back, a space medicine researcher says the crew, which includes Canadian astronaut Jeremy Hansen, are physically ready for when the time comes to launch.

"They've been preparing for years, so what is a few more months," said Dr. Farhan Asrar, a physician, space medicine researcher and associate dean at Toronto Metropolitan University's School of Medicine.

"One thing that I've always kind of appreciated and respected in the life of astronauts … is it's always expecting the unexpected and how do you best prepare for that?"

NASA has targeted an April 1 launch for Artemis II, with a six-day launch window running through April 6 announced last week.

Pioneering scientist Suzuki reflects on his life’s work

It is hard to believe that Vancouver’s David Suzuki, an internationally renowned geneticist and environmental activist best-known in Canada for his popular television series The Nature of Things with David Suzuki, turns 90 years old on March 24.

NASA clears its Artemis moon rocket for an April launch with four astronauts following repairs

CAPE CANAVERAL, Fla. (AP) — NASA cleared its moon rocket on Thursday for an April launch with four astronauts after completing the latest round of repairs.

The 322-foot (98-meter) rocket will roll out of the hangar and back to the pad next week at Florida's Kennedy Space Center, leading to a launch attempt as early as April 1. It will mark humanity's first trip to the moon in more than 50 years.

The Artemis II crew should have blasted off on a lunar flyaround earlier this year, but fuel leaks and other problems with the Space Launch System rocket interfered.

Although NASA managed to plug the hydrogen fuel leaks at the pad in February, a helium-flow issue forced the space agency to return the rocket to the Vehicle Assembly Building for repairs, bumping the mission to April.

No time for stolen hours

I’m a time zone and time change veteran.

I spent almost two years living in Saskatchewan, where the clocks never change from Central Standard Time, and you just learn to live with it.

I also spent many years living in a province knocked askew from the top of the clock, where, when everyone else was celebrating New Year’s at midnight, we were already at 12:30 a.m.

I’ve lived in the Newfoundland time zone, along with Atlantic, Eastern, Central and Mountain zones, along with every one of their spring-forward, fall-back time changes.

King penguins are the rare species benefiting from a warming world. But that could change

WASHINGTON (AP) — The warming world has disrupted the timing for plant and animal reproduction, and it's usually bad news for species that depend on each other — like flowers blooming too early and pollinating bees arriving too late. But researchers have found the rare critter that's getting a boost from the change: King penguins.

A new study of 19,000 king penguins in a sub-Antarctic island chain found their breeding is starting 19 days earlier than it did in 2000. Mating earlier has increased the breeding success rate by 40%, according to a study in Wednesday's journal Science Advances.

The study of timing in nature is called phenology. It's been a major concern for biologists because predators and prey and pollinators and plants are mostly adapting to warmer climates at different rates. And that means crucial mismatches in timing.

It's especially common in birds and pollinating species such as bees. Most birds, especially in North America, aren't keeping pace with changes in phenology, according to Clemson University biological sciences professor Casey Youngflesh, who wasn't part of the study.

Pentagon’s chief tech officer says he clashed with AI company Anthropic over autonomous warfare

A top Pentagon official said Anthropic's dispute with the government over the use of its artificial intelligence technology in fully autonomous weapons came after a debate over how AI could be used in President Donald Trump's future Golden Dome missile defense program, which aims to put U.S. weapons in space.

U.S. Defense Undersecretary Emil Michael, the Pentagon's chief technology officer, said he came to view the AI company's ethical restrictions on the use of its chatbot Claude as an irrational obstacle as the U.S. military pursues giving greater autonomy to swarms of armed drones, underwater vehicles and other machines to compete with rivals like China that could do the same.

“I need a reliable, steady partner that gives me something, that’ll work with me on autonomous, because someday it’ll be real and we’re starting to see earlier versions of that," Michael said in a podcast aired Friday. "I need someone who’s not going to wig out in the middle.”

The comments came after the Pentagon formally designated San Francisco-based Anthropic a supply chain risk, cutting off its defense work using a rule designed to prevent foreign adversaries from harming national security systems.

Spacecraft’s impact changed asteroid’s orbit around the sun in a save-the-Earth test, study finds

CAPE CANAVERAL, Fla. (AP) — An asteroid that NASA used for target practice a few years ago was nudged into a slightly different route around the sun, findings that could help divert a future incoming killer space rock, scientists reported Friday.

It’s the first time that a celestial body’s orbit around the sun was deliberately changed. The asteroid that NASA's Dart spacecraft slammed into was never a threat to Earth.

“This study marks a notable step forward in our ability to prevent future asteroid impacts on Earth,” the international research team wrote in Science Advances.

The changes were slight — reductions of just one-tenth of a second and one-half of a mile (720 meters) to a solar lap spanning two years and hundreds of millions of miles (kilometers), according to the scientists.

First Nations awaiting Hydro consults

With licences for two major Manitoba Hydro projects set to expire later this year, affected First Nations await consultation — and want to see change.

Licences for the Churchill River Diversion and Lake Winnipeg Regulation projects, first issued in the 1970s, expire Sept. 1 and Aug. 1, respectively.

The diversion directs water to five stations accounting for roughly 75 per cent of Manitoba’s power generation. The latter project allows Hydro to generate power by manipulating Lake Winnipeg’s water levels.

There is no timeline for the licence renewals, said Environment Minister Mike Moyes. He said that would be dependent on consultations with impacted First Nations.

Family embraces challenges, rewards of launching a fruit orchard

Growing up on a farm near Boissevain taught Kelvin Hildebrandt many things. But becoming an orchardist has meant taking a comprehensive and strategic approach to acquiring a whole new set of skills.

In the process, Hildebrandt has consulted with local orchardists, including well-known growers like Betty Kehler and Bob Pizey who ran Plum Ridge Farm, a popular u-pick orchard located in the Interlake region near Teulon.

“They taught me a great deal,” says Hildebrandt.

Hildebrandt has also been influenced by Jean Spencer who owned a 150-tree apple orchard near Miami. “Jean was very welcoming and let me take care of her trees for a while,” he says.

The delicate art of pressing flowers

When early explorers travelled the four corners of the world in search of botanical treasures and plant knowledge, they faced many challenges collecting and transporting live plant material. In the 19th century, the development of the Wardian case — a glazed box that held soil and water — enhanced the survival rate of live plants on long sea journeys.

But highly detailed botanical illustrations also served as a visual record for early botanists and scientists to study plants from distant parts of the world. The technique of pressing and drying all the parts of individual plants on paper made it possible to preserve plant specimens.

Today, herbariums around the world, including those at Manitoba Museum and the University of Manitoba, house extensive collections of pressed, dried plants stored in specialized, climate-controlled conditions. Scientists use these specimens to determine the rarity of species and understand environmental changes.

Enduring art form

U of M partners with firm behind proposed sand mine to study Manitoba groundwater

University of Manitoba researchers will soon have a new, non-invasive tool to study the province’s vast groundwater resources after inking a partnership with Alberta-based mining company Sio Silica.

“If the technology works … it’s going to provide a mechanism to do real-time monitoring of changes in groundwater,” Ricardo Mantilla, an associate professor in the university’s civil engineering department and lead researcher for the project, said in an interview.

The emerging technology — called absolute quantum gravimetry — can measure changes in gravity caused by changes in groundwater levels, allowing researchers to better understand the flow and storage of underground water resources without the need for “expensive and disruptive” drilling, he said.

“That obviously has applications for (Sio Silica), but it can have very important implications for how we understand groundwater in aquifers in our province.”

City sewage plant megaproject progresses amid need for more funding

The finishing touches are being put on four massive fibreglass sewage pipes inside a two-and-a-half metre thick concrete tunnel 20 metres underground.

When the work is done, they’ll start pumping out millions of litres of raw sewage per day.

The building that houses them may look modest, but it was made with as much concrete as half of the Canada Life Centre, with still some to go.

“We’ve got at least double that in the balance of the facility in other areas,” said Rob Black, the project director for the upgrade of the North End sewage treatment plant on Main Street North.

Clear Lake group withdraws review against Parks Canada

Fairness for Clear Lake has decided to withdraw its judicial review against Parks Canada following a court delay that pushed the 2025 boat ban hearing to May.

Agricultural innovation takes hit in federal cuts

Everyone knew cuts to federal programs and jobs were coming.

Something must give if elected officials are to make good on promises to address what many characterized as Canada’s bloated bureaucracy and ballooning deficits, while boosting its military defence systems and protecting the economy from a neighbour gone rogue.

And while the Canadian effort to shrink the cost of governing is a little less dramatic than that in the U.S. a year ago, the application of across-the-board cuts has been anything but surgical.

Farmers and unions, who rarely agree on anything, are united in opposition to news Agriculture and Agri-Food Canada is closing three research facilities and four research farms, and cutting around 650 positions. The cuts include a host of programs, including those focused on organic farming, regenerative agriculture and climate adaptation.

Agriculture and Agri-Food Canada announces closure of research operations, job cuts

Agriculture and Agri-Food Canada says it is closing seven of its research operations as part of the federal government's efforts to cut the size of the public service.

The federal department said research centres in Guelph, Ont., Quebec City and Lacombe, Alta., as well as four satellite research farms across Nova Scotia, Saskatchewan and Manitoba are closing.

It said so far, approximately 665 department positions have also been reduced and nearly 1,050 employees received notices on Thursday.

"There are no imminent site closures, and any wind-down of scientific operations would follow a careful decision process that could take up to 12 months," the department said in a statement Friday.
