RALEIGH, N.C. -- Massive wildfires in the Western U.S. and Canada have triggered poor air quality in North Carolina over the past few weeks, and health experts say it is important for residents to know traveling smoke can cause more than hazy skies.

Dr. Stephanie Johannes, pediatrician and health programs manager for CleanAIRE NC, said research shows tiny particles can penetrate the lungs and cause a range of health problems.

"We know that when that air from the West Coast shows up here in North Carolina, it's affecting our air quality here," Johannes explained. "And it's really putting people - everybody - at risk for health problems, but especially those people that already have some heart or lung condition, especially people with asthma."

The Centers for Disease Control and Prevention said wildfire smoke can make people prone to lung infections, including the coronavirus. According to the National Oceanic and Atmospheric Administration, a warmer and drier climate is expected to lead to more frequent and intense fires and smoke plumes, which in turn are expected to affect more people.

Johannes pointed to research published earlier this year by scientists at the Scripps Institution of Oceanography at the University of California, San Diego, which found the fine particles in wildfire smoke can cause more harm to human lungs than particulate matter from other sources such as car exhaust.

"There's a lot of data that shows that this particular kind of pollution contributes to symptoms like eye and respiratory-tract infections," Johannes noted. "But also to really severe things, worsening heart and lung conditions that people have and even causing premature death."

She encouraged families with young children, the elderly and those with a chronic disease to regularly check their local air-quality index at airnow.gov. Air-quality indexes use ozone and particle pollution measurements from zero to 300.

"Anything over 100 is unhealthy for people in those sensitive groups," Johannes advised. "And anything over 150 is something that's risky, really, for everybody."

Johannes recommended planning outdoor activities or exercising on lower air-pollution days, and said it is important to talk to your doctor or child's pediatrician about air-quality concerns.

New Mexico's decades-long drought combined with climate change have more farmers and ranchers embracing the six healthy soil principles, tailoring how each parcel of land is managed.

New Mexico's farming practices date back at least 2,500 years but the state's Healthy Soil Working Group said the arid climate and diverse ecology make a one-size-fits-all approach ineffective.

Dave Dubois, climatologist at New Mexico State University, said the recent storm should improve this year's snowpack but farmers and ranchers must plan five or 10 years into the future.

"The scenarios from climate change models are showing warmer temperatures, hotter droughts and then more evaporation," Dubois explained. "How do you manage all that in a system where we still have agriculture as our cultural identity?"

Agriculture is the state's third-largest industry after energy and aerospace. The majority of New Mexico's farmland is heavily dedicated to growing grass, which feeds livestock, provides sod and serves as a cover crop to protect soil health between harvests.

Many factors contribute to soil degradation: intensive farming practices, deforestation, overgrazing, urbanization and erosion.

Ernest Diswood, a Navajo conservation leader, said using regenerative techniques, he has been improving his range soil since 2009.

"We're seeing, despite the drought now, about 21 species of grasses and we're probably between 700 to 1,000 pounds an acre," Diswood outlined. "For the Navajo Indian Reservation, that's usually a pretty good number."

Keeping soil covered is one of the six healthy soil principles.

Ralph Vigil, owner of Molino de la Isla Organics and an eighth-generation acequia farmer, changed his practices nearly 20 years ago. A lack of moisture led him to reduce the East Pecos land where he grows organic vegetables from five acres, to a half-acre. To improve the soil, he now uses drip irrigation and other conservation techniques.

"The acequia sees less water; I've done more cover-cropping to try to help build my soil, keeping my cover present at all seasons because (of) no snowpack, lack of rain and wind," Vigil emphasized. "Wind is beating us up and it doesn't go away. So, just trying to keep that soil covered at all times."

Significant cuts made by the Trump administration to the Natural Resources Conservation Service are expected to reduce climate-friendly programs nationwide.

Nine in ten people in Colorado and across the globe are worried about climate change and want governments to do something about it, according to a new survey, but they mistakenly assume that others do not share their view.

Anthony Leiserowitz, director of the Yale Program on Climate Change Communication, called this a perception gap.

"The average person believes that other people in their own country tend not to worry about climate change that much when, in fact, the majority of people in most countries do worry about climate change," he said.

That gap in perception has real-world policy implications. In the U.S., almost 80% of congressional staffers underestimated their constituents' support for reducing climate pollution, sometimes by more than 50 percentage points. Leiserowitz said helping more people understand that they are not in the minority could unlock a social tipping point that moves leaders to act.

He pointed to one example where 96% of liberal Democrats and 78% of conservative Republicans supported helping farmers protect and restore soil to absorb more carbon dioxide. But he said progress is stymied by misperceptions.

"If your perception is that Republicans are absolutely against climate policy, then many people might then conclude - especially if you're a policy maker - that we shouldn't be taking action when, in fact there's overwhelming support, even among conservative Republicans," he continued.

Decades of misinformation campaigns, aiming to protect fossil-fuel company profits, play a big role in perception gaps. But Leiserowitz said gaps also persist because any two individuals, not knowing what the other thinks, are likely to avoid topics they believe are controversial, including climate change.

"So, that leads neither of us to talk about it. Well, now expand that to 300 million people, and you can see that we start slipping down this 'spiral of silence.' Nobody talks about it, so nobody talks about it. Which means nobody talks about it," he concluded.

As Boulder and local governments across the U.S. turn to courts to pay for rebuilding after wildfires, floods and other extreme weather events linked to a changing climate, a new study shows it is now possible to pinpoint specific companies that could be held accountable.

Justin Mankin, associate professor of geography at Dartmouth College and study coauthor, said using advanced modeling, his team calculated a price tag for the impacts of extreme heat, just one climate hazard, linked to carbon dioxide and methane emissions from 111 companies over 30 years.

"The world would be $28 trillion more wealthy had those companies found ways to mitigate the extreme heat impacts of those emissions," Mankin reported.

Researchers found 10 fossil-fuel companies - including Chevron, ExxonMobil and Saudi Aramco - were responsible for half of the total losses.

Oil and gas companies have argued in court it was not possible to assign blame to their company's carbon or methane molecules in the atmosphere compared with all the other molecules released. They have also noted oil and gas production has produced numerous public benefits and wealth.

Using emissions data and advanced climate models, Mankin pointed out it is now possible to see what the world would look like if any particular corporation had not produced emissions. He added other industries have not gotten off the hook, including "Big Pharma," just because they produced breakthrough medicines and vaccines.

"That doesn't absolve them for their role in, say, generating the opioid crisis," Mankin contended. "Courts have ruled that they had a role in generating the opioid crisis, and needed to compensate harmed individuals for that."

Hundreds of lawsuits have been filed to hold corporations and trade associations accountable for climate damages. Colorado's Supreme Court has heard oral arguments but has not yet ruled on a case brought by San Miguel County and the city and county of Boulder seeking compensation from ExxonMobil and Suncor Energy.
