, the West Coast is burning
— から orange skies in San Francisco to the ash rain in Southern California
, the Golden State looks like it has been given the Hollywood dystopia treatment
But it’s not a dystopia — it’s a reality: The climate crisis has arrived — and on the West Coast, people are getting a front-row view of just how bad it is via the air they breathe.
“Climate change has not just made the extreme heat waves that coincided with the fires worse
,” Daniel Swain
, a climate scientist at UCLA and the National Center for Atmospheric Research
, told CNN earlier this week
“The bigger effect is the more subtle, long-term warming. That couple of degrees of (average) warming over decades … you don’t notice it as much, but it’s still there lurking in the background, sucking extra moisture out of the vegetation and the soil.”
Breathing: A ‘luxury’ during fire season
Satellite images from National Oceanic and Atmospheric Administration (海洋大気庁) reveal that the wildfire smoke continued to blanket most of the West Coast on Thursday morning.
But West Coast residents don’t need NOAA to tell them: They just need to step outside and breathe — or attempt to.
なので a recent Time magazine journalist noted
, during fire season in California
“breathing feels like a luxury for more and more months of the year.
木曜日現在, the South Coast Air Quality Management District said a smoke advisory remained in effect for most of Los Angeles County and parts of Orange
, Riverside and San Bernardino counties
幸運なことに, many people in the fire areas are already equipped with masks (残念ながら, that’s due to their concerns over catching or spreading Covid).
博士. John Balmes
, a pulmonologist at University of California San Francisco
, told CNN that an N95 or an N100 respirator
, certified by NIOSH
, is the best respiratory protection from both Covid-19 and PM2.5
, the tiny lung-damaging pollution particles that are found in the worst concentrations of wildfire smoke
Cloth masks, 彼は言った, prevent transmission of SARS-CoV-2 — “but offer little protection from wildfire smoke.”
Balmes recommends that people stay indoors with the windows closed and put central ventilation on recirculate mode, or create a clean air room with a portable HEPA air filter device.
The California Air Resources Board echoed similar tips, adding that people should listen and watch for air quality reports and warnings.

Smoky skies and ash rains
Fires have destroyed over 3,900 structures in California, as of Thursday, そして少なくとも 14,000 firefighters are battling 29 major fires up and down the state.
Authorities in many communities have had to order mandatory evacuations, 以上 170,000 customers recently went without power to prevent future blazes.
And with all the fires comes the bad air quality.
“Hurts to breathe, extremely light headed,” another Twitter user wrote. “Feeling so sick.”
“Anybody else’s eyes been burning from all this smoke and bad air quality or is it just me
??” 書きました 別の
いくつか, like Juliana Park, narrowly escaped one of the many fires while on a getaway over Labor Day Weekend.
24歳, who lives in Mountain View, had gone on a five-hour road trip from the Bay Area toward Sierra National Forest for a backpacking trip last Saturday. Her group had hiked for about an hour when they heard lightning.
“That was our cue to turn around,” 彼女はCNNに語った. “We didn’t have cell service either, so we thought it would be safest to go back as soon as possible.”
As they walked back to the car, Park said they started to see the sky was a different color.
“It was orange, but also very gray,” 彼女は言いました. “I was wearing a white shirt and you could see the black ash on my shirt, and the white ash falling on top of our eyelashes. When we got to the car, we had a red Honda, you could see on the hood black and white ash. It was getting harder to breath and see.”
They made it home safely
, but passed a smaller fire on their way
, which Park posted a video of on Twitter. Later in the week
, Park woke up to orange Bay Area skies
“The smoke and ash are acting like nature’s version of an Instagram filter
,” CNN meteorologist Judson Jones 共和党の選挙法の見直しに反対する
. “The particles in the air are refracting sunlight similar to the way small air particles do when the sun sets or rises.
Massive plumes of smoke generated by the wildfires raging across the state has led to the longest stretch of unhealthy air quality alerts on record in the San Francisco Bay Area, と 25 straight days of Spare The Air alerts, Bay Area Air Quality Management District spokeswoman Erin DeMerritt told CNN.
The previous record was 14 consecutive days during the 2018 Camp Fire that devastated the city of Paradise.
Park and her roommate kept all their apartment windows closed.
Climate change concerns
If you have paid attention to the headlines — and the global climate change activists — it shouldn’t come as a surprise that the fires have worsened.
Even earlier this year — in pre-pandemic times — Australia saw its own devastating wildfires that burned across the country last year and into 2020.
A new analysis published in March showed that the fires were made far more likely and intense by the climate crisis
. Scientists found that the chances of the kind of extreme weather that triggered the blazes have increased by more than
30% 以来 1900, and that fire conditions like this are at least four times more likely than they were at the start of the 20th century
それでも, it’s hard to understand the impact when it’s not necessarily close to home.
“I would say growing up in Orange County, I didn’t really pay attention to the fires,” Park said. “But I think we can all say no matter how long you’ve lived in California, that the fires have gotten considerably worse.”
以上 3.1 million acres, twice the size of Delaware, have burned in California as a result of the wildfires ravaging the state, according to a Cal Fire press release issued Thursday.
“This year’s fire season has been a record-breaking year
, in not only the total amount of acres burned
, だが 6 トップの 20 largest wildfires in California history have occurred in 2020,
” said Cal Fire
政府. Gavin Newsom has pointed to climate change as a primary factor
This time last year, California saw 4,927 fires that burned 118,000 エーカー, according to the governor. に 2020, があった 7,606 blazes so far.
In Oregon, 政府. Kate Brown said more than 300,000 acres have burned and for the parts that aren’t yet on fire, “the worst fire conditions in three decades persist.”
And in Washington, more acres were burned on Monday than were charred in the past 12 fire seasons, 政府. Jay Inslee said.
結論? “We have been more and more bad air quality days due to increased wildfires driven by climate change,” said Balmes, the pulmonologist.
など, West Coasters must be even more careful.
“The people at greatest risk of adverse health effects from wildfire smoke are those with pre-existing hear and lung disease,” Balmes said. “とはいえ, even healthy people may be at increased for respiratory infections, including COVID-19.”
