Michigan experts warn of worsened air quality after Trump climate move


Washington — Experts warn air quality will worsen because of the Trump administration’s repeal of the legal basis for federal climate rules, despite a top federal regulator saying the move “does not change regulations on traditional air pollutants and air toxics.”

U.S. Environmental Protection Agency head Lee Zeldin made that statement Thursday in the Oval Office as he and President Donald Trump touted the major deregulatory action. They both suggested the change would boost the U.S. auto industry.

“This EPA is committed to providing clean air for all Americans,” Zeldin said. “Powering the great American comeback is based on the singular focus of providing clean air, land and water for all Americans, while harnessing the greatness of the American economy.”

It is true that repealing the Obama-era EPA’s 2009 “endangerment finding” will leave intact federal rules meant to limit harmful emissions of criteria air pollutants identified more than 50 years ago in the Clean Air Act. Those pollutants include noxious gases like sulfur dioxide, nitrogen dioxide and carbon monoxide that cause asthma, lung issues and neurological damage.

The mass introduction of catalytic converters on new motor vehicles in the 1970s helped drastically curtail emissions of those gases over the next two decades, and the devices will surely remain on gas-powered cars and trucks to ensure they continue meeting federal standards. (Electric vehicles, notably, do not have converters because they have no tailpipe emissions.)

Experts disagreed, however, with Zeldin’s suggestion that there would not be “clean air” implications from the move to wipe out a generation of climate-focused regulations.

“Carbon dioxide pollution and other greenhouse gases are correlated with the production of other air pollutants like particulate matter and nitrogen oxides,” said Erik Nordman, director of the Institute for Public Utilities at Michigan State University.

“Measures that reduce carbon dioxide and greenhouse gases often reduce those other pollutants. That’s a co-benefit of these greenhouse gas regulations. So by removing or lowering standards for greenhouse gases, we would expect those other pollutants that are tightly correlated with greenhouse gases to increase,” he said in a phone interview.

Catalytic converters are one example of the link between what Zeldin called “traditional” pollutants and greenhouse gases.

The devices work by causing chemical reactions that transform highly toxic criteria pollutants into less harmful — or in some cases harmless — gases and substances. One byproduct is harmless water vapor. Another primary one is carbon dioxide, a greenhouse gas that causes climate change in the long term but is not instantly poisonous to humans at low ambient levels.

But even as converters have become more effective over time, academic research shows, they still do not block all of the most air-quality-harming pollutants. And because vehicles that use more fuel have higher emissions, the risk for worsened air quality is greater.

Nordman said the Trump administration’s endangerment finding repeal “kind of locks in a lower standard, so that will result in cars that are less fuel efficient than they might have been otherwise. That will result in greater pollution than we would have seen otherwise.”

The environmental policy expert added that those impacts will play out most over the longer term because “energy and transportation infrastructure that we’re building today will be more polluting than it otherwise could be, and we’re going to lock in that pollution for decades.”

He said other Trump administration actions — like the order to keep a coal plant open in Michigan — will have more immediate impacts on air quality.

Jeff Holmstead, who was an EPA official under former President George W. Bush, said Thursday he expected little near-term impact in air quality from the federal policy change, noting that automakers “have very long planning cycles.”

But Tom Luben, a senior research scientist at the University of Michigan School of Public Health and former air pollution researcher at the EPA for almost 20 years, was blunt in condemning the Trump administration’s repeal of the endangerment finding.

The action, Luben wrote ahead of the announcement, “would threaten the health of millions of Americans.”

“An increase in ground-level ozone concentrations has been linked to respiratory health problems ranging from decreased lung function and asthma exacerbations to increased emergency department visits and hospital admissions,” he added, similarly raising air quality concerns.

Luben continued: “Certain parts of the population are especially vulnerable to these effects, including children, older adults, pregnant people, and individuals with pre-existing health conditions.”

Beyond air quality, the research scientist also lamented climate-related impacts of the policy change.

“In addition to increased air pollution, the proliferation of extremely hot days, floods, storms, droughts, and fires linked to a changing climate will impact the health of the American people.”

In announcing the repeal move, however, Trump dismissed climate-change concerns: “… this has nothing to do with public health. This was all a scam.”

Michigan football emphasizes return of discipline under new regime

Michigan football emphasizes return of discipline under new regime


play

The buzzword continued to come up in Schembechler Hall, from each one of the captains.

From Bryce Underwood to Jordan Marshall, Rod Moore to Trey Pierce − Michigan football players around for the previous regime and in the case of the latter two, the one before that too − each said Wednesday, March 25, that there’s a noticeable difference within the program under new coach Kyle Whittingham.

For Moore, a sixth-year player who will likely become a third-time captain when the official leaders are voted on later this summer, he recognized the vibe.

“I would say it’s kind of a similarity to coach Harbaugh’s regimen,” he said. “It’s a lot more strict than the past two years, and the weight room has kind of been a night-and-day difference than the past two years. We feel a lot stronger, a lot more progress.”

The Wolverines finished winter conditioning and Whittingham graded it with an “A+.” Hope is often the dominant mode at this time of year and adding a new coaching staff to what’s generally a positive time creates little surprise that the Wolverines are raving about the new system.

But beyond the platitudes and clichés, there are tangible examples. Take Pierce: The projected starting defensive tackle has trimmed his weight to 300 pounds while adding muscle mass to his overall frame.

“Something new that we have now is that whenever we start meetings, there’s like a loud air horn that goes off throughout the whole building,” Moore said. “The past two years, we would start the meeting at 2:30, but now we start the meeting at 2:25, even though it’s a 2:30 meeting. Just everyone being five minutes early. The coaches are holding everyone accountable in the meetings, going to class.

“Just the little things that makes a team great, not just the big, broad things that everyone sees.”

There was an implication from everyone, though nothing said explicitly, that the past two seasons featured little enforcement. Most players would show up on time for lifts, but there were those who didn’t, with few repercussions.

“It’s the little things,” Pierce said. “Guys being late for lifts, guys not being where they’re supposed to be, whether it’s [missing] class. Just enforcing that a little bit heavier, that type of thing. … A lot of coaches say that when you’re being recruited in front of your parents. But for [Whittingham] to say that in front of the huddle after practice and say, ‘That’s why I’m here,’ I would say, ‘OK, he cares. He gets it.’”

Throughout the offseason, some who’ve spent time inside the facility said the weightlifting sessions had notably more juice. The past two years felt like a carryover of the previous years in terms of style, but accountability and discipline wavered.

Now, with Doug Elisaia leading the strength and conditioning room, there are different philosophies.

Practices are a bit shorter these days – two hours – but as Marshall said, “I don’t stop moving at practice, like, we’re always doing something that’s not only going to help with us competing with teams, but our conditioning.”

Marshall believes it can take the Wolverines to the next level, he said.

Just more than a week into spring ball, players are oozing confidence. Not just in their skills − the running back room is deep, the wide receiver room has as much raw talent as at any point the past decade, the offensive line returned multiple key pieces, the secondary added depth and the defensive tackles feel underrated − but in mindset.

U-M had early, demanding lifting sessions during winter conditioning, with a clear organization.

“It introduces that factor of toughness, like we’ve been through this at 6:30 a.m., 6:15 a.m., all these days in the grind together,” Pierce said. “It improves team bonding, and puts you in the headspace of, we’ve done harder stuff than this, and nothing can break us.”

The difference between winning and losing can often be razor-thin. Will this pay off when it counts during the season?

“If I can trust you to do things maybe you don’t want to do,” Marshall said, “then I can trust you on the field when it’s the fourth quarter and we have one minute left.”

Michigan school bus driver wins national hero award


LANSING, Mich. (InvestigateTV) — A Lansing school bus driver has won a national award for going above and beyond behind the wheel.

Jackie Wilkerson-Brown, known as Miss Jackie by students, transports children to and from Lansing’s Gardner and Lewton schools. She recently became the first recipient of the 2025 School Bus Driver Hero Award.

“I was like, seriously, seriously, seriously, and I just started crying,” Wilkerson-Brown said.

The award was presented by School Bus Fleet Magazine. Teachers and parents nominated Wilkerson-Brown for the honor.

Known for being fun and firm

Wilkerson-Brown is known for being fun and firm with students. She hands out candy and leads students in games like the name game on rides home.

“Being a mirror bus driver is just sitting in your bus and, ‘Sit down, stop doing that, stop jumping over the seat,’” Wilkerson-Brown said. “You have to sometimes get up out of your seat and face-to-face with your children.”

Posters of positivity line the inside of her bus.

“I keep it on my bus, and I just try to remind the kids that, you know, smile,” she said. “Kind vibes, happy lives.”

‘Unbelievable honor’

Patrick Dean, president of Dean Transportation, said the recognition is significant.

“This is an unbelievable honor for Jackie,” Dean said. “Jackie exemplifies everything it means to be a superhero bus driver.”

Todd Sharp, operations manager for Dean Transportation, said Wilkerson-Brown treats students as her own.

“When those students step up on her bus, she treats them as her own. They’re her children while they’re in her care,” Sharp said.

Wilkerson-Brown said she loves her job.

“I’m trying not to get emotional, because I love my job, I love what I do,” she said. “If you call my phone right now, the message is going to say, ‘Hey I’m busy being awesome.’ So, because I am awesome, I am awesome, and then to receive this award, and then it came and I’m employed by Dean Transportation, oh, my God, it doesn’t get any better than that.”
