Smoke Is a Big Health Risk as California Wildfires Rage On
By Nneka Leiba
Deadly wildfires continue to blaze in Northern and Southern California. Dozens of people are dead, hundreds more missing and entire communities have been destroyed.
Our foremost concern is for the immediate victims. (Here's how to help.) But even hundreds of miles from the fires, much of the state is blanketed in dangerous smoke. For more than a week, the air quality in San Francisco, Los Angeles and other major cities has been classified as "unhealthy" or "very unhealthy."
The wildfires are releasing tons of pollutants into the air that will linger long after the fires are put out. Hazardous chemicals that may be present in building structures or products—such as asbestos insulation, vinyl materials, plastics, electronics casings and flame retardants—are released into the air as these things burn, creating airborne carcinogens.
The extremely fine particles in soot and smoke harm our lungs. The particulates can trigger symptoms like difficulty breathing, coughing and headaches, or worsen respiratory diseases, like asthma. They also can damage the heart, circulatory system and brain.
Health experts agree that the best defense is to stay indoors.
Although the poor air quality puts everyone at risk, children, the elderly and people with asthma, cardiovascular or respiratory diseases are particularly vulnerable. People in these groups should take extra precautions. Exposure to air pollution during pregnancy can affect thyroid hormone levels in the developing fetus, and may contribute to reduced birth weight, preterm birth and a greater risk of chronic health conditions later in life.
Monitor your local air quality using resources like the EPA's AirNOW website, and pay attention to air quality reports and advisories posted by your local government. You can also search AirNOW using your zip code to learn more about your air quality.
Here are the Environmental Working Group's (EWG) tips to staying safe in areas with poor air quality:
- Remain indoors when you can.
- Keep windows and doors closed.
- Keep indoor air as clean as possible. Avoid smoking, and cook without generating fumes.
- If you have a central air system, make sure it's fitted with the highest-rated filter it can accommodate. The American Lung Association recommends using filters with Minimum Efficiency Reporting Value or MERV, of 10 or higher. Also, operate the central air system with the fan on to ensure constant movement of air through the system.
- Replace HVAC filters frequently so they work with maximum efficiency.
- Consider a portable air cleaner to use in bedrooms, children's rooms and nurseries. California's Air Resources Board has a list of certified air cleaners here. We recommend air cleaners equipped with a high-efficiency, or HEPA, filter. Beware ionizing electronic air cleaners that may intentionally produce ozone, a potent respiratory irritant and the main component of ground-level smog.
- When you have to go outdoors in an area with polluted air, consider wearing a face mask or a respirator labeled N95 or P100. These can be found at most hardware stores and will help to filter out the fine particles in smoke. Consult the California Department of Public Health's tips to make sure you're using your mask correctly and maximizing protection.
- Whether you're inside or outside in one of these areas, avoid vigorous activity.
- In extreme cases, consider leaving the area until the air quality improves.

Colette Pichon Battle gave a December 2019 TEDWomen Talk on the stark realities of climate change displacement, and people took notice. The video racked up a million views in about two weeks. The attorney, founder, and executive director of the Gulf Coast Center for Law & Policy (GCCLP) advocates for climate justice in communities of color. Confronted with evidence showing how her own South Louisiana coastal home of Bayou Liberty will be lost to flooding in coming years, the 2019 Obama Fellow dedicates herself to helping others still reeling from the impacts of Katrina face the heavy toll that climate change has taken—and will take—on their lives and homelands. Her work focuses on strengthening multiracial coalitions, advocating for federal, state, and local disaster mitigation measures, and redirecting resources toward Black communities across the Gulf South.

"These are not just wildfires, they are climate fires," Jay Inslee, Governor of Washington State, said as he stood amid the charred remains of the town of Malden west of Seattle earlier this month. "This is not an act of God," he added. "This has happened because we have changed the climate of the state of Washington in dramatic ways."
'These Aren't Wildfires'<p>Sam Ricketts, who led climate policy and strategy for Governor Jay Inslee's 2020 presidential campaign, tweeted on September 11 that "These aren't wildfires. These are #climatefires, driven by fossil fuel pollution."</p><p>"The rate and the strength and the devastation wrought by these disasters are fueled by climate change," Ricketts told DW of fires that have burnt well over 5 million acres across California, Oregon, Washington State, and into neighboring Idaho. </p><p>In a two-day period in early September, Ricketts notes that more of Washington State burned than in almost any entire fire season until now, apart from 2015. </p><p>California, meanwhile, was a tinderbox after its hottest summer on record, with temperatures in Death Valley reaching nearly 130 degrees Fahrenheit, according to the U.S. National Weather Service. It has been reported as the hottest temperature ever measured on Earth.</p>
<div id="29ad9" class="rm-shortcode" data-rm-shortcode-id="8346fe7350e1371d400097cd48bf45a2"><blockquote class="twitter-tweet twitter-custom-tweet" data-twitter-tweet-id="1306969603180879872" data-partner="rebelmouse"><div style="margin:1em 0">Drought-parched wetlands in South America have been burning for weeks. https://t.co/pjAKdFcKPg #Pantanal https://t.co/ImN2C5vwcp</div> — NASA Earth (@NASA Earth)<a href="https://twitter.com/NASAEarth/statuses/1306969603180879872">1600440810.0</a></blockquote></div><p>As evidenced by Australia's apocalyptic Black Summer of 2019-2020, fires are burning bigger and for longer, with new records set year-on-year. Right now, Brazil's vast and highly biodiverse Pantanal wetlands are suffering from catastrophic fires.</p>
#climatefires Started in Australia<p>Governor Inslee this month invoked the phrase climate fires for arguably the first time in the U.S., according to Ricketts.</p><p>But the term was also used as fires burnt out of control in Australia in late 2019. In the face of a 2000km (more than 1,200 miles) fire front, and government officials and media who <a href="https://www.dw.com/en/trump-climate-change-denial-emissions-environment-germany-fake-heartland-seibt/a-52688933" target="_blank">played down the link to climate change</a>, Greens Party Senator Sarah Hanson-Young and a friend decided that reference to bushfires was inadequate. </p><p>"We both just said, we've got to start calling them climate fires, that's what they are," the Australian Senator told DW.</p><p>Hanson-Young says scientists have been warning for decades that these would be the effects of global heating. "We've been told these kinds of extreme weather events and destruction is what climate change would look like, and it's right here on our doorstep," she said from her home state of South Australia — where by early September fire warnings had already been issued.</p><p>"Calling them climate fires was making it absolutely crystal clear. It is essential that there's no ambiguity," she said </p><p>Having deliberately invoked the term, Hanson-Young soon started to push it on social media via a #climatefires hashtag. </p>
How to Talk About the Urgency of Global Heating<p>The need to use more explicit language when talking about extreme weather events linked to climate change is part of a broader push to express the urgency of global heating. In 2019, activist Greta Thunberg tweeted that the term "climate change" did not reflect the seriousness of the situation. </p><p>"Can we all now please stop saying 'climate change' and instead call it what it is: climate breakdown, climate crisis, climate emergency, ecological breakdown, ecological crisis and ecological emergency?" she wrote. </p><p>"Climate change has for a long time been talked about as something that is a danger in the future," said Hansen-Young. "But the consequences are already here. When people hear the word crisis, they understand that something has to happen, that action has to be taken."</p><p><span></span>Some terms are now used in public policy, with state and national governments, and indeed the EU Parliament, declaring an official climate emergency in the last year. </p>
Words That Reflect the Science<p>But while the West Coast governors all fervently link the fires to an unfolding climate crisis, U.S. President Donald Trump continues to avoid any reference to climate. In a briefing about the fires, he responded to overtures by Wade Crowfoot, California's Natural Resources Secretary, to work with the states on the climate crisis by stating: "It'll start getting cooler. You just watch." Crowfoot replied by saying that scientists disagreed. Trump rejoined with "I don't think science knows, actually." </p><p>It was reminiscent of the anti-science approach to the coronavirus pandemic within the Trump administration, <a href="https://www.dw.com/en/donald-trump-admits-playing-down-coronavirus-risks/a-54874350" target="_blank" rel="noopener noreferrer">at least publicly</a>. Fossil fuel companies are also benefiting from his disavowal of climate science, with the Trump administration having <a href="https://www.dw.com/en/opinion-trumps-paris-climate-accord-exit-isnt-really-a-problem/a-51124958" target="_blank" rel="noopener noreferrer">pulled out of the Paris Agreement</a> and reopened fossil fuel infrastructure like the Keystone XL pipeline. </p><p>But the science community has responded, with Scientific American magazine endorsing Trump's Democratic presidential challenger Joe Biden, the first presidential endorsement in its 175-year history. </p><p>Hanson-Young says the use of explicit language like climate fires has also been important in Australia due to the climate denialism of politicians and the press, especially in publications owned by Rupert Murdoch. As fires burnt out much of Australia's southeast coast, they were commonly blamed on arson — a tactic also recently used in the U.S.</p>
Climate Rhetoric Could Help Decide Election<p>The language of climate has begun to influence the U.S. presidential election campaign, with Democratic nominee Joe Biden labelling President Trump a "climate arsonist."</p><p>Biden is touting a robust climate plan that includes a 2050 zero emissions target and a return to the Paris Agreement. Though lacking the ambition of The New Green Deal, it has been front and center of his policy platform in recent days, at a time when five hurricanes are battering the U.S. Gulf Coast while smoke blanketing the West Coast spreads all the way to the East. </p><p>People are experiencing the climate crisis in a visceral way and almost universally relate to the language of an emergency, says Ricketts. "They know something is wrong."</p>

World's Richest One Percent Are Producing More Than Double the Carbon Emissions as the Bottom 50 Percent
A new report from Oxfam found that the wealthiest one percent of the world produced a carbon footprint that was more than double that of the bottom 50 percent of the world, The Guardian reported. The study examined 25 years of carbon dioxide emissions and wealth inequality from 1990 to 2015.
