    The historic wildfires raging across the West Coast are pumping record amounts of pollution into the air — with swaths of smoke spreading at least 5,000 miles to Europe, data shows. The dense smoke coverage — already blamed for this week’s hazy skies over New York — reached Britain and other parts of northern Europe last week and is forecast to head back in the coming days after a brief respite, according to the European Union’s Copernicus Atmosphere Monitoring Service (CAMS). Data shows that the West Coast fires have been “tens to hundreds of times more intense” than the nationwide average in the 18 years the agency has monitored blazes, it said. They have “already emitted far more carbon in...
    When I close my eyes and think about that day in the late 1970s, I’m struck by the colors. The bright red of my favorite shirt. The silvery gray of smog sifting through the trees. The leaves, bleached by chemicals in the air, were soft-edged blobs of an indiscriminate dark hue. I was in college and I’d driven from Northridge to Pasadena to visit the Norton Simon Museum. I don’t remember the paintings. What I do remember is the air pollution, thick and viscous. It is hard not to think about smog during this terrible mid-September. California is on fire, millions of acres torched, tens of thousands of people evacuated. The pall of smoke from Northern California’s flames has been...
    By Faith Karimi and Alexandra Meeks | CNN Doctors warn that bad air quality stemming from smoke produced by the wildfires ravaging Western states could make people more vulnerable to coronavirus infections. “Multiple studies have shown a correlation between higher levels of pollution in the air and greater spread and severity of Covid-19 cases,” said Dr. Brad Spellberg, chief medical officer of the Los Angeles County-USC Medical Center, citing several studies conducted in the United States, China and Italy. “Some studies have also shown that exposure of lung tissue to pollution may increase susceptibility to viral infections.” Smoke from wildfires can irritate the lungs and cause inflammation that can affect the immune system, said Dr. Rekha Murthy, an infectious disease...

Josh Edelson/AFP via Getty Images Doctors say that poor air quality, especially in places that are experiencing extreme wildfires, can cause an increase in coronavirus cases. Dr. Brad Spellberg told Los Angeles local news that " there is evidence that exposure of lungs to bad air quality can increase the protein in the virus." An infectious disease specialist told CNN that the smoke from wildfires could "irritate the lungs" and "affect the immune system."

    As dozens of wildfires rage across California, air pollution levels are skyrocketing. The United States Environmental Protection Agency (EPA) measures air pollution with the Air Quality Index - an AQI of 50 or below represents good air quality.  A score of between 201 and 300 is considered 'very unhealthy,' while anything above 300 is considered 'hazardous,' with emergency conditions in effect for all residents. In some regions of the California now, the AQI is above 700, according to the U.S. government's AirNow website.  The result is an environmental crisis that could easily become a health crisis.

    CONCORD (KPIX) – All of the debris, ash and smoke from the wildfires has blanketed the Bay Area and made the air especially unhealthy. Air quality her is the worst in the world. Smoke from raging fires has nearly blotted Mount Diablo out of the skyline, in Contra Costa County. The smoke isn’t just hanging high in the air, but also filling our lungs – making respiratory problems like asthma and chronic obstructive pulmonary disease (COPD) worse. “We also know that exposure to wildfire smoke especially makes the elderly more susceptible to cardiac outcomes – things like heart attacks, strokes, arrhythmias all increase,” says Dr. Mary Prunicki, the director of air pollution and health research at the Sean...
    With dozens of major fires burning from Wine Country to the Santa Cruz Mountains, Salinas to the Mount Hamilton foothills, smoke levels are bad across the Bay Area and Northern California. Breathing it can harm your health. There are several websites to find real-time information about air quality and smoke levels in your community. All of the sites use the U.S. Environmental Protection Agency’s Air Quality Index, which ranks air pollution levels on a 0-500 scale, with green and yellow being the best, and red and purple the worst. They are: 1) Purple Air – Founded in 2015, the site sells outdoor air monitors that measure dust, smoke, soot, and other particulates. The site tracks thousands of its sensors on...
    Smoke In Europe there are an average of 65,000 forest fires each yearBut the region is also enveloped by seasonal clouds of smoke from flames elsewhere. During the colder winter months, burning domestic wood contributes to a significant fraction of the smoke in the atmosphere, especially in urban areas, according to Professor Nenes. Further work is needed to understand the many sources of air pollution. Unraveling these sources is the goal of the Aeromet project. It is developing new ways to better analyze aerosols and particulates that pollute the air, particularly in urban areas of Europe. It is currently difficult to distinguish between those that come from natural sources, such as dust in the air and salt that the...
    Smoke from the fire that ravaged a Navy warship in San Diego Bay contained elevated levels of toxins, but air-quality authorities say area residents have little to fear.  The local Air Pollution Control District found smoke from the USS Bonhomme Richard contained a dozen potentially harmful substances but they were at levels which don't pose known health risks, the San Diego Union-Tribune reported. The district issued the Navy a notice of violation for creating a public nuisance and contaminating the air. The findings from the San Diego County Air Pollution Control District contradict earlier statements by the Navy that 'there's nothing toxic in there.'  The local Air Pollution Control District found smoke from the USS Bonhomme Richard contained a...

    BALTIMORE (WJZ) – Maryland lawmakers announced this week $3 million in federal funding for the University of Maryland Center for Environmental Science to develop technology that reduces air pollution and recycles carbon waste. U.S. Senators Ben Cardin and Chris Van Hollen and Congressmen Dutch Ruppersberger, John P. Sarbanes, and Kweisi Mfume issued the following statement in a press release: “This new federal funding will invest in innovative new technologies that can improve air quality in our communities for the good of public health and of our environment. We are excited for UMCES and the opportunities this project creates, especially as we work to advance solutions that reduce carbon emissions and combat climate change in Maryland.” This project is one of 11...
    Children who live in cities plagued by air pollution, a high population density, 'unwalkable' infrastructure and have parents who smoke are more likely to be obese, a study has revealed. High levels of nitrogen dioxide inside and outside the home alongside particulate matter between PM2.5 and PM10, which is produced by cars and burning fossil fuels, were linked to growing waistlines. Those going to school in densely populated areas with few services and facilities, were also more at risk, regardless of their socio-economic status. Childhood obesity has spiralled at an alarming rate worldwide, and now affects almost a third of children in Europe. Children exposed to pollutants such as nitrogen dioxide and particulate matter between PM2.5 and PM10 were...
    AN ENORMOUS plume of Saharan dust, nicknamed 'Godzilla', is heading for the U.S. bringing the "worst air pollution in 50 years". The Saharan Air Layer (SAL) first appeared on satellite images captured over Africa in June according to the National Oceanic and Atmospheric Administration (NOAA). 11The cloud of dust blanketed the Caribbean on June 22 as it heads towards the U.S.Credit: AP:Associated Press 11The dust cloud dominated the skyline in San Juan, Puerto RicoCredit: Twitter The colossal cloud, usually found between 5,000 and 20,000 feet above ground level, is formed by powerful winds lifting sand and mineral particles off the surface of the Sahara and into the air. It's assumed that strong updrafts sent sandy surface winds blowing the cloud...
    The coronavirus pandemic has hit Richmond hard. It has caused more cases of COVID-19 and more deaths than in other cities in Contra Costa County like Concord or Walnut Creek. Dr. John Balmes  Why? Richmond is a city that has large Latinx and African-American populations, the groups we know are at most risk of dying from COVID-19. And the neighborhoods in Richmond where people of color live are exposed to more air pollution than many other places in the county. The pollutant that we are especially concerned about in Richmond neighborhoods is fine particulate matter (PM2.5) or “soot.” Where does PM2.5 come from in Richmond? It comes from highways, trains, ships, the Chevron oil refinery and the dust blowing off...
    A new study reveals global efforts to improve air quality have fallen short. Researchers found half of the world’s population is exposed to increasing air pollution, with some areas reaching an amount five times above safety levels. The team, in collaboration with the World Health Organization, notes it is low- and middle-income areas with the highest concentrations. The contributing culprits include the inefficient use of energy by households, industry, the agriculture and transport sectors and coal-fired power plants. Scroll down for video  The study analyzed trends in global air quality between 2010 and 2016, against the efforts made by countries around the world to reduce pollution, including both short and long term policies Professor Shaddick, Chair of Data Science...
    (CNN)The way we got here -- a Covid-19 contagion that has sickened more than six million people and killed nearly 380,000 globally -- is absolutely horrible, but the pandemic has awakened the world to at least one thing that's positive: Clean air and healthy cities are a blessing. The air in Delhi was clean enough under a lockdown in late March that residents finally could see the blue sky. The famous smog in Los Angeles lifted. Where I live, in Salt Lake City, Utah, the air was clear enough that I could see all the way across a typically gray and polluted valley. Honking horns and smoke-belching trucks were replaced with the songs of birds. "I have not seen...
    (CNN)Scientists believe they have identified the world's cleanest air, free from particles caused by human activity, located over the Southern Ocean, which surrounds Antarctica.In a first-of-its-kind study of the bioaerosol composition of the Southern Ocean, researchers from Colorado State University identified an atmospheric region which remains unchanged by human activity.Weather and climate are closely linked, connecting each part of the world with other regions. As the climate changes rapidly because of human activity, scientists and researchers struggle to find a corner of the Earth unaffected by people. However, Professor Sonia Kreidenweis and her team suspected that the air over the Southern Ocean would be least affected by humans and dust from the world's continents.Major milestone: Coal consumption falls behind renewable...
