smoke from us wildfires boosting health risk for millions

BILLINGS, Mont. -
Climate change in the western United StatesS.
That means more intense and frequent wildfires can produce smoke, which scientists say will sweep across the continent, affect tens of millions of people and lead to a surge in premature deaths.
This emerging reality has prompted people in urban and rural areas to prepare for another Blue Sky summer on the West Coast and Rocky Mountains --
It is widely expected that these areas will suffer the biggest fires due to dryer and warm conditions.
\"There\'s so little we can do.
We have air purifiers and masks.
Otherwise, we\'re like \"Please don\'t burn,\" said Sarah Rochelle Montoya of San Francisco, who fled her home with her husband and children last fall, from a catastrophic fire of about 150 miles, the smoke that covered the city (241 kilometres)away.
Other sources of air pollution in the United States are decreasing. S. as coal-
On the highway, the power plant is closed and the number of old cars is reduced.
But in some areas, these improvements in air quality are being eliminated by the adverse effects of a large amount of smoke that can spread hundreds or even thousands of miles at intersections
Rural winds, the researchers say.
As the 2019 wildfire season has warmed up, fires from Southern California to Canada to Alaska are also erupting, and authorities are scrambling to protect the public from the smog hanging over the town again.
Seattle officials recently announced that they would renovate five public buildings. free shelters.
Scientists at NASA and universities are improving satellite images to predict where smoke will spread and how strong it will be.
Local authorities are using these forecasts to produce real
Time alerts encourage people to stay indoors when things get unhealthy.
The scope of this problem is huge: over the next 30 years, more than 300 counties in the West will see more serious wildfire smoke waves, sometimes even weeks longer than in the past few years, says atmospheric researchers led by Yale and Harvard teams.
Last year\'s campfire killed 85 people, destroyed 14,000 houses in California\'s paradise for nearly two weeks, and the smoke from the fire flooded the San Francisco community where Montoya and her husband lived together, trevor McNeil and their three children.
When people rush to buy masks and indoor air purifiers, the hardware store looks like a line.
The city\'s famous open-air cable car was shut down.
The school keeps the children at home or cancels classes, and the church\'s soup kitchen protects the homeless from smoke.
Three children in Montoya have respiratory disease, she said, and doctors say it may be a precursor to asthma.
This will make them in those most-
There is a risk of being hurt by wildfire smoke, but the family can\'t find a child
There are masks or air filters of sufficient size.
They sold out everywhere.
In desperation, her family eventually fled to a relative\'s holiday home in Lake Tahoe.
The children are very happy that they can go out again.
\"We really need our children to be able to breathe,\" Montoya said . \".
In addition to the most vulnerable, the smoke from wildfire was once considered a brief nuisance.
But now in some areas, the disease is considered a recurring, increasingly serious public health threat, said James cruxks, a health investigator at the National Jewish Health Center at Denver Medical Center.
\"There are too many fires, and you have too many headwinds, so that you have gained more and more particle levels and ozone from fires in weeks and weeks,\" cruxks said . \"
One of the places is Ashland, Oregon, a city with a population of 21,000, known for its summer months.
Shakespeare festival in Oregon.
In the last two summers Ashland has had smoke for about 40 days
Chris Chambers, director of the fire department\'s wildfire division, said the air was full.
More than two forced cancellations last year
More than a dozen outdoor shows
Family doctor Justin Adams says his asthma and other respiratory problems are the most serious people who smoke, and he wants some people to see it for a long time --
Health effects.
\"It\'s basically like they started smoking again after two months,\" he said . \".
In 2018, voters passed a bond measure that included funds to transform Ashland school with a \"washer\" to filter smoke.
Other public buildings and businesses already have them.
The community alert system allows 6,500 people to receive emails and text messages when the National Weather Service issues a smoke alert.
\"We really feel we have made a conscious effort to adapt to climate change,\" Chambers said . \".
\"But you can\'t just live in it for a lifetime.
\"The direct damage caused by frequent fires in the West is obvious.
In California alone, more than 33,000 homes, ancillary buildings and other buildings have been burned over the past two years, killing 146 people.
What is more difficult to understand is the health impact of tiny particles in smoke that can cause heart disease, breathing problems, and other diseases.
The particles, which are about 1/30 of the diameter of human hair, go deep into the lungs, causing cough, chest pain, and asthma attacks.
Children, the elderly and those with lung disease or heart disease are at the most risk.
Linda Smith, head of the California Air Resources Commission\'s health department, said death could occur in days or weeks after exposure to smoke.
Over the past decade, as many as 2,500 people have died prematurely in the United States each year. S. from short-
According to scientists from the Environmental Protection Agency, the term wildfire smoke is exposed. The long-
Jeff Pearce, associate professor of atmospheric science at Colorado State University, said the term effect has only recently become the focus, estimating that chronic smoke exposure causes about 20,000 premature deaths each year.
Since the weather is hotter and drier and the fire season is longer, the figure could double by the end of the century, Pierce said.
His team compared the health impact of known air pollution to future climate scenarios to derive its predictions.
The results show that smoke will spread as a major pollutant even in areas typically unrelated to wildfire, such as the South and Northeast.
Even among wildfire experts, until recently, the understanding of the health effects of smoke remains elusive.
But as people become more aware of climate change, attitudes change and begin to look at the potential consequences of wildfires.
According to Loretta Mickley, a senior climate researcher at Harvard University, residents in Northern California, Western Oregon, Washington state and northern Rocky Mountains are expected to suffer the most severe increase in smoke exposure.

\"Climate change adds a new variable to the mixture and adds smoke, which will be detrimental to our other efforts to clear the air through regulations.
This is an unexpected source of pollution and health hazards.
