Canada draws link between June heat wave and climate change in landmark study

Published

 on

For the first time, the Canadian government has conducted a rapid analysis of a period of extreme heat and determined its connection to human-caused climate change.

The analysis conducted by Environment and Climate Change Canada (ECCC) found that a heat wave in Ontario, Quebec and Atlantic Canada between June 17 and 20 was made two to 10 times more likely because of climate change.

“In all regions, the event was made much more likely by the human influence on the climate,” Greg Flato, senior research scientist with Environment and Climate Change Canada, said during a briefing for reporters.

The analysis noted abnormally high daytime temperatures, high humidity and warmer-than-normal nighttime lows. Bathurst and Saint John, N.B., in particular set all-time records for the hottest temperature since data was first gathered in the 1870s.

ECCC’s study is the start of a pilot project, where researchers will analyze weather data and climate model simulations to compare how these types of events have changed between today’s climate and the cooler pre-industrial one.

Flato said the heat wave ongoing in Western Canada will also be analyzed, as will others in the future. The department will expand this system to analyze other extreme weather events, he said. An ECCC official said their rapid attribution system is based on peer-reviewed techniques.

‘Not just a one-off study’

The findings add to a growing area of research known as rapid attribution, where scientists use models to quickly determine to what extent climate change is linked to an extreme weather event, such as heat waves, floods and storms.

The federal government’s commitment to ongoing attribution work marks a “really significant development,” said Frederike Otto, co-founder of World Weather Attribution (WWA), a U.K.-based group that conducts attribution studies.

“When you have not just a one-off study, but have this on a regular basis, that obviously helps to see how, not only how things have changed already, but how quickly things are changing.”

Otto said other countries have done attribution studies but Canada appears to be the first to commit to doing so on an ongoing basis.

Attribution studies don’t say definitively whether climate change caused a specific weather event, but rather, the statistical likelihood of climate change causing a specific weather event and the degree to which it made the event worse. (In some instances, natural weather patterns, such as El Niño, also play a role in driving up the temperature.)

The conclusions can help governments make better decisions, such as planting trees in particularly hot parts of a city, or ensuring vulnerable populations have access to cool spaces, Otto said.

“If you know that the heat wave that you’re experiencing right now is not an act of God or just bad luck with nature, but that it is actually something … you actually expect to see every 10 years or so, that means you have to have infrastructure that can deal with these levels of heat,” Otto said.

In the past, WWA has determined that climate change more than doubled the likelihood of the conditions that led to Quebec’s record-setting wildfire season, and calculated that the devastating 2021 heat dome in Western Canada would occur every five to 10 years in a world that has warmed by 2 C.

Such studies are not immediately peer-reviewed and published in scientific journals, given the effort to release the information soon after an event, but are based on peer-reviewed modelling techniques — and many end up being published, the WWA said.

‘A lever to elevate the conversation’

Sarah Henderson, scientific director of environmental health services at the British Columbia Centre for Disease Control, said these kinds of studies “can reinforce the message that climate change is affecting the health and well-being of Canadians now.”

A heat wave has brought record high temperatures to California and Nevada that are already substantially higher than last year. The heat has people searching for ways to stay cool and firefighters working to keep wildfires from spreading.

“It just serves to put these events in the context of climate change for the public and for public health professionals,” she said.

“It’s a lever to elevate the conversation and to ensure that climate change is never dropped from the conversation around extreme heat.”

Tua Tagovailoa sustains concussion after hitting head on turf in Dolphins’ loss to Bills

Published

 on

MIAMI GARDENS, Fla. (AP) — Miami Dolphins quarterback Tua Tagovailoa sustained a concussion for the third time in his NFL career, leaving his team’s game Thursday night against Buffalo after running into defensive back Damar Hamlin and hitting the back of his head against the turf.

Tagovailoa remained down for about two minutes before getting to his feet and walking to the sideline after the play in the third quarter. He made his way to the tunnel not long afterward, looking into the stands before smiling and departing toward the locker room.

The Dolphins needed almost no time before announcing it was a concussion. The team said he had two during the 2022 season, and Tagovailoa was diagnosed with another concussion when he was a college player at Alabama.

Dolphins coach Mike McDaniel said Tagovailoa would get “proper procedural evaluation” and “appropriate care” on Friday.

“The furthest thing from my mind is, ‘What is the timeline?’ We just need to evaluate and just worry about my teammate, like the rest of the guys are,” McDaniel said. “We’ll get more information tomorrow and take it day by day from here.”

Some players saw Tagovailoa in the locker room after the game and said they were encouraged. Tagovailoa spoke with some players and then went home after the game, McDaniel said.

“I have a lot of love for Tua, built a great relationship with him,” said quarterback Skylar Thompson, who replaced Tagovailoa after the injury. “You care about the person more than the player and everybody in the organization would say the same thing. Just really praying for Tua and hopefully everything will come out all right.”

Tagovailoa signed a four-year, $212 million extension before this season — a deal that makes him one of the highest-paid players in the NFL — and was the NFL’s leading passer in Week 1 this season. Tagovailoa left with the Dolphins trailing 31-10, and that was the final score.

“If you know Tua outside of football, you can’t help but feel for him,” Bills quarterback Josh Allen said on Amazon following the game. “He’s a great football player but he’s an even greater human being. He’s one of the best humans on the planet. I’ve got a lot of love for him and I’m just praying for him and his family, hoping everything’s OK. But it’s tough, man. This game of football that we play, it’s got its highs and it’s got its lows — and this is one of the lows.”

Tagovailoa’s college years and first three NFL seasons were marred by injury, though he positioned himself for a big pay bump with an injury-free and productive 2023 as he led the Dolphins into the playoffs. He threw for 29 touchdowns and a league-best 4,624 yards last year.

When, or if, he can come back this season is anyone’s guess. Tagovailoa said in April 2023 that the concussions he had in the 2022 season left him contemplating his playing future. “I think I considered it for a time,” he said then, when asked if he considered stepping away from the game to protect himself.

McDaniel said it’s not his place to say if Tagovailoa should return to football. “He’ll be evaluated and we’ll have conversations and progress as appropriate,” McDaniel said.

Tagovailoa was hurt Thursday on a fourth-down keeper with about 4:30 left in the third. He went straight ahead into Hamlin and did not slide, leading with his right shoulder instead.

Hamlin was the player who suffered a cardiac arrest after making a tackle during a Monday night game in January 2023 at Cincinnati, causing the NFL to suspend a pivotal game that quickly lost significance in the aftermath of a scary scene that unfolded in front of a national television audience.

Tagovailoa wound up on his back, both his hands in the air and Bills players immediately pointed at him as if to suggest there was an injury. Dolphins center Aaron Brewer quickly did the same, waving to the sideline.

Tagovailoa appeared to be making a fist with his right hand as he lay on the ground. It was movement consistent with something that is referred to as the “fencing response,” which can be common after a traumatic brain injury.

Tagovailoa eventually got to his feet. McDaniel grabbed the side of his quarterback’s head and gave him a kiss on the cheek as Tagovailoa departed. Thompson came into the game to take Tagovailoa’s spot.

“I love Tua on and off the football field,” Bills edge Von Miller said. “I’m a huge fan of him. I can empathize and sympathize with him because I’ve been there. I wish him the best.”

Tagovailoa’s history with concussions — and how he has since worked to avoid them — is a huge part of the story of his career, and now comes to the forefront once again.

He had at least two concussions during the 2022 season. He was hurt in a Week 3 game against Buffalo and cleared concussion protocol, though he appeared disoriented on that play but returned to the game.

The NFL later changed its concussion protocol to mandate that if a player shows possible concussion symptoms — including a lack of balance or stability — he must sit out the rest of the game.

Less than a week later, in a Thursday night game at Cincinnati, Tagovailoa was concussed on a scary hit that briefly knocked him unconscious and led to him being taken off the field on a stretcher.

His second known concussion of that season came in a December game against Green Bay, and he didn’t play for the rest of the 2022 season. After that, Tagovailoa began studying ways where he may be able to fall more safely and protect himself against further injury — including studying jiu-jitsu.

“I’m not worried about anything that’s out of my hands,” McDaniel said. “I’m just worried about the human being.”

Too much? Many Americans feel the need to limit their political news, AP-NORC/USAFacts poll finds

Published

 on

NEW YORK (AP) — When her husband turns on the television to hear news about the upcoming presidential election, that’s often a signal for Lori Johnson Malveaux to leave the room.

It can get to be too much. Often, she’ll go to a TV in another room to watch a movie on the Hallmark Channel or BET. She craves something comforting and entertaining. And in that, she has company.

While about half of Americans say they are following political news “extremely” or “very” closely, about 6 in 10 say they need to limit how much information they consume about the government and politics to avoid feeling overloaded or fatigued, according to a new survey from the Associated Press-NORC Center for Public Affairs Research and USAFacts.

Make no mistake: Malveaux plans to vote. She always does. “I just get to the point where I don’t want to hear the rhetoric,” she said.

The 54-year-old Democrat said she’s most bothered when she hears people on the news telling her that something she saw with her own eyes — like the Jan. 6, 2021, attack on the U.S. Capitol — didn’t really happen.

“I feel like I’m being gaslit. That’s the way to put it,” she said.

Sometimes it feels like ‘a bombardment’

Caleb Pack, 23, a Republican from Ardmore, Oklahoma, who works in IT, tries to keep informed through the news feeds on his phone, which is stocked with a variety of sources, including CNN, Fox News, The Wall Street Journal and The Associated Press.

Yet sometimes, Pack says, it seems like a bombardment.

“It’s good to know what’s going on, but both sides are pulling a little bit extreme,” he said. “It just feels like it’s a conversation piece everywhere, and it’s hard to escape it.”

Media fatigue isn’t a new phenomenon. A Pew Research Center survey conducted in late 2019 found roughly two in three Americans felt worn out by the amount of news there is, about the same as in a poll taken in early 2018. During the 2016 presidential campaign, about 6 in 10 people felt overloaded by campaign news.

But it can be particularly acute with news related to politics. The AP-NORC/USAFacts poll found that half of Americans feel a need to limit their consumption of information related to crime or overseas conflicts, while only about 4 in 10 are limiting news about the economy and jobs.

It’s easy to understand, with television outlets like CNN, Fox News Channel and MSNBC full of political talk and a wide array of political news online, sometimes complicated by disinformation.

“There’s a glut of information,” said Richard Coffin, director of research and advocacy for USAFacts, “and people are having a hard time figuring out what is true or not.”

Women are more likely to feel they need to limit media

In the AP-NORC poll, about 6 in 10 men said they follow news about elections and politics at least “very” closely, compared to about half of women. For all types of news, not just politics, women are more likely than men to report the need to limit their media consumption, the survey found.

White adults are also more likely than Black or Hispanic adults to say they need to limit media consumption on politics, the poll found.

Kaleb Aravzo, 19, a Democrat, gets a baseline of news by listening to National Public Radio in the morning at home in Logan, Utah. Too much politics, particularly when he’s on social media sites like TikTok and Instagram, can trigger anxiety and depression.

“If it pops up on my page when I’m on social media,” he said, “I’ll just scroll past it.”
