1966 New York City smog

Air-pollution episode in New York City May 2025 February 2025 1966 New York City smog 1966 NYC smog by Neal Boenzi NYT.jpg A black-and-white, panoramic view of New York City as seen from a great height. A vast number of buildings and skyscrapers can be seen. A hazy, smoky gas overlays the entire city like a blanket, with a fairly clear skyline only in the far distance at the horizon. Near the closest buildings, the smog appears thin and wispy. The smog appears thicker and thicker around buildings that are farther away from the photographer's position, until shorter buildings near the horizon are almost entirely shrouded and impossible to see under a thick layer of smog. Near the horizon, the clustered tops of tall skyscrapers emerge from within the smog. On November 25, 1966, the front page of The New York Times featured this photograph by Neal Boenzi. Taken the morning before, the photo shows a view facing south from the Empire State Building.The New York Times 1966a Roy Popkin of the EPA said the "surrealistic" image made Lower Manhattan look like a science-fiction "Cloud City".Popkin 1986 28 November 23–26, 1966 Acute smog in New York City; lesser smog throughout the New York metropolitan area 40.713 N 74.006 W type:event_region:US-NY inline,title Heat inversion over East CoastPopkin 1986 27 168 (estimate from 1967 medical study)Bird 1967d The 1966 New York City smog was a major air-pollution episode and environmental disaster, coinciding with that year's Thanksgiving holiday weekend. Smog covered the city and its surrounding area from November23 to 26, filling the city's air with damaging levels of several toxic pollutants. It was the third major smog in New York City, following events of similar scale in 1953 and 1963. On November 23, a large mass of stagnant air over the East Coast trapped pollutants in the city's air. For three days, New York City was engulfed in dangerously high levels of carbon monoxide, sulfur dioxide, smoke, and haze. Pockets of air pollution pervaded the greater New York metropolitan area, including parts of New Jersey and Connecticut. By November 25, the smog became severe enough that regional leaders announced a "first-stage alert". During the alert, leaders of local and state governments asked residents and industry to take voluntary steps to minimize emissions. Health officials advised people with respiratory or heart conditions to remain indoors. The city shut off garbage incinerators, requiring massive hauling of garbage to landfills. A cold front dispersed the smog on November 26, and the alert ended. In the months that followed, medical researchers studied the smog's impact on health. City officials initially maintained that the smog had not caused any deaths, but it soon became clear that the smog had significantly harmed public health. A study published in December 1966 estimated that 10% of the city's population had suffered adverse health effects, such as stinging eyes, coughing, and respiratory distress. A statistical analysis published in October 1967 found that 168 deaths had likely been caused by the smog. The smog catalyzed greater national awareness of air pollution as a serious health problem and a political issue. The government of New York City updated local laws on air-pollution control. Prompted by the smog, President Lyndon B. Johnson and members of Congress worked to pass federal legislation regulating air pollution in the United States, culminating in the 1967 Air Quality Act and the 1970 Clean Air Act. The extent of harms from subsequent pollution events, including the health effects of pollution from the September 11 attacks and incidents of pollution in China, have been judged by reference to the 1966 smog in New York. 3 Background Smog Air pollution in the United States Smog in general and types of smog right vertical Nelson's Column during the Great Smog of 1952.jpg A view of London obscured by heavy smoke Great Smog of London, 1952 SUNLIGHT AND SMOG - NARA - 552395 (restored).jpg Los Angeles, shrouded in haze Smog over Los Angeles, 1973 The word "smog" (a portmanteau of "smoke" and "fog") is used to describe several forms of air pollution commonly found in urban and industrialized areas.Goklany 1999 24 There are several ways to define and categorize types of smog, with some sources defining two main types of smog: smoky "London Pea soup"-style smog and hazy "Los Angeles"-style smog.Kuttler 1979 236 London smog describes particulate matter (for example sulfur dioxide, smoke, and soot) from stationary industrial sources (typically coal combustion from industrial chimneys) mixing with naturally occurring fog.Kuttler 1979 237; New York Academy of Medicine Committee on Public Health 1966 590 : "British studies support the view that pollution in [London and its surrounding area] is attributable overwhelmingly to the combustion of coal and oil, which contain compounds of sulfur as impurities in varying degrees. Smoke and sulfur dioxide are now measured routinely in London and are used as indices of pollution. It is important for New Yorkers to recognize that these two pollutants are present in roughly the same amounts in London and New York." Los Angeles smog, or photochemical smog, results from the combustion of petroleum (and other petrochemicals) and emission of exhaust gas, usually by motor vehicles and petrochemical plants.Kuttler 1979 238New York Academy of Medicine Committee on Public Health 1966 606 : "In contrast to the composition of pollution in London, the type in Los Angeles contains little coal smoke, fog, or sulfur dioxide. Auto exhaust gases are the principal source of pollution. Photochemical reactions between volatile organic compounds, especially olefinic hydrocarbons, and the exhaust of nitrogen produce highly reactive peroxy-compounds and ozone. More precisely, photochemical smog is the product of "secondary" pollutants (ozone, oxidants) that form when hydrocarbons (or volatile organic compounds), carbon monoxide, nitrogen oxides, and other chemicals react together in sunlight.Goklany 1999 24 Photochemical smog arrived in modern cities in the 1940s and 1950s with the popularization of motor vehicles and development of new power plants.Goklany 1999 24 thumb|201x201px|May 1973 photo of East River and Manhattan skyline in heavy smog London smog and Los Angeles smog are not exclusive to their namesake cities by any means. They are found in urban areas throughout the world, and both types of smog are commonly found intermingled within the same region.Kuttler 1979 236 At the time of the 1966 smog—and for two decades prior—air pollution in New York City combined the characteristics of London smog and Los Angeles smog. The city's smog in that period was caused by a combination of stationary sources, such as industrial coal-burning,New York Academy of Medicine Committee on Public Health 1966 590; Loory 1966. and mobile sources, such as motor vehicles.Popkin 1986 27; Goklany 1999 27. Although smog is generally a chronic condition, unfavorable weather conditions and excessive pollutants can cause intense concentrations of smog that can cause acute illness and death. Because of their unusual visibility and lethality, these intense smog events have often been publicized in the media.Goklany 1999 24; Freeman 2005 175; Fensterstock Fankhauser 1968 35. In news reports, acute smogs have historically been characterized as disasters or, more specifically, environmental disasters.Popkin 1986 27; Wise 1970 3–5. An acute "smog event" may also be called simply "a smog", a smog "episode", or a "killer smog" (if it caused, or had the potential to cause, deaths).

See also: Kihss 1963; Life 1966; Wise 1970 207. According to scientific studies from the period, more than 60 metropolitan areas in the US suffered from "extremely serious air pollution problems", and "probably no American city of more than [50,000] inhabitants enjoys clean air the year round."Wise 1970 207 The air "over much of the eastern half of the country [was] chronically polluted", and the nation's most-polluted population centers were New York City, Chicago, Los Angeles, St. Louis, and Philadelphia.Wise 1970 207 New York City's pre-1966 air pollution was reportedly the worst of any American city.Kihss 1963 Although the "persistently glaring" photochemical smog of Los Angeles was more visible, more "infamous,"Freeman 2005 175 and subject to a greater degree of public attention,Life 1966 New York City had more total emissions and many more emissions proportional to its land area.Kihss 1963 However, New York's surrounding landscape and climate were naturally conducive to atmospheric circulation, which ordinarily prevented high concentration of smog within the city.Kihss 1963 As such, the problem was mostly invisible most of the time.Life 1966 While Los Angeles is surrounded by mountains that tend to trap airborne pollutants, New York City's open topography and favorable wind conditions usually disperse pollutants before they can form concentrated smog. If a city with the climate and landscape of Los Angeles had had the high emissions of mid-1960s New York, rapid accumulation of airborne pollutants would have quickly rendered it uninhabitable.Kihss 1963 New York's smog event of 1966 was preceded by two other major episodes: the first in November 1953, the second in January–February 1963.1963smog Sources differ on the timing of the 1963 smog. It is variously described as occurring in January–February, October, or November, and it is possible that minor smog events occurred during those months. January–February is most likely to be the correct time for that year's most significant smog event, because it is the period Dr. Leonard Greenburg identified in his study of significant excess deaths caused by smog.McCarroll 1967 206 The 1963 smog is sometimes inaccurately described as occurring in 1962; other sources list a 1962 smog as a fourth major New York City smog, alongside the smogs of 1953, 1963, and 1966. There was a smog event in November 1962, but Greenburg's studies found it had not resulted in significant excess deaths.McCarroll 1967 205 Medical scientists led by Leonard Greenburg compared the number of deaths recorded during periods of acute smog with the number of deaths from the same time in other years. Based on their statistical analysis, Greenburg's team determined that the smogs coincided with excess deaths.mortality The term "excess deaths," or mortality displacement, refers to a statistically significant, temporary increase above the expected mortality rate in a given population over a given period of time. In Greenburg's studies on mortality during New York City smog events, the method to measure excess deaths was to compare the expected number of deaths and the actual number of deaths for a particular period. Where the actual number of deaths significantly exceeds the expected number, it can be inferred that a major event that occurred at the same time (such as a heat wave or, in this case, a smog event) caused or contributed to the excess deaths. Greenburg inferred that the smog caused or contributed to those deaths.McCarroll 1967 204 An estimated 220–240 deaths were caused by the six-day 1953 smog;Iglauer 1968; Johnson 2002; Karapin 2016 171. an estimated 300–405 deaths were caused by the two-week 1963 smog.Iglauer 1968McCarroll 1967 206 Other minor episodes of smog occurred in the city before 1966, but they were not accompanied by statistically significant excess deaths.McCarroll 1967 206 City air monitoring New York City See caption New York City location Manhattan.svg Blue pog.svg 1 right white Harlem Courthouse 10 Harlem Courthouse 40.801111 -73.939167 left 10 Because the Department of Air Pollution Control only measured within the immediate vicinity of the Harlem Courthouse—pinpointed above in blue on a map of New York, with its surrounding borough of Manhattan highlighted in red—its readings were a crude representation of the city's overall air quality.Reeves 1966a; Schumach 1966. thumb|upright=1.18|alt=Photograph of a brick building with gables, archways, an octagonal corner tower, and a four-faced clock.|In 1966, New York City had only a single air quality measurement station: the Harlem Courthouse (pictured in 2009).Schumach 1966 In 1953, the city opened a laboratory to monitor pollution that would become its Department of Air Pollution Control.The New York Times 1966b At the time of the 1966 smog, air quality measurements were recorded from only a single station, the Harlem Courthouse building on East 121st Street,Schumach 1966 run by Braverman and his staff of 15.The New York Times 1966b Taking measurements from a single station meant that the index reflected conditions in the immediately surrounding area, but served as a crude, unrepresentative gauge of overall air quality across the entire city.Reeves 1966a; Schumach 1966. The Interstate Sanitation Commission, a regional agency run by New York, New Jersey, and Connecticut and headquartered at Columbus Circle, also relied on the Harlem Courthouse laboratory. Formed in 1936, the advisory agency was authorized in 1962 by New York and New Jersey to oversee air pollution issues.Kaplan 1966 The department quantified pollution using an air quality index (AQI), a single number based on combined measurements of several pollutants.The New York Times 1966a AQI measurements in the United States are now standardized and overseen by the EPA, but in the 1960s, local governments in different regions used "a confusing and scientifically inconsistent array of air quality reporting methods".Peterson, Russell W., "Foreword", p. iv in Thom Ott 1975. By 1964, the Department of Air Pollution Control had developed an AQI called the SCS Air Pollution Index (SCS API), combining measurements of sulfur dioxide (SO2), carbon monoxide (CO), and coefficient of haze (also called smoke shade) into a single number. The city laboratory recorded the presence of those three pollutants measured in amount (by concentration in the air) and duration.The New York Times 1966a SO2 and CO were measured by parts-per-million (ppm) and smoke shade was measured in millions of particles per cubic foot (mppcf). The department continuously monitored these pollutant levels and recorded the hourly averages.Sanderson 1977 43 The data for those three pollutants were combined into a single number using a weighted formula developed by department co-founder Moe Mordecai Braverman.Reeves 1966a The SCS API formula was as follows:Cousins et al. 1966 126; Sanderson 1977 43–44. (SO2 ppm × 20) + (CO ppm × 1) + (Smoke mppcf × 2) = SCS API The index average was 12, with an "emergency" level if the index was higher than 50 for a 24-hour period.The New York Times 1966a The average of 12 was determined from data collected between 1957 and 1964 showing average levels of 0.18ppm SO2, 3ppm CO, and 2.7mppcf smoke levels.formula average Using the SCS API formula, the average had been calculated based on these measurements:Cousins et al. 1966 127(0.18 × 20) + (3 × 1) + (2.7 × 2) = 12 SCS APICousins et al. 1966 127 The "emergency" level of 50 was announced in 1964.Reeves 1966a The index system used by the city in 1966 is not in use anywhere today and was unique to the city even at the time; the 1966 smog itself prompted scientists to reexamine and improve the city's methodology for recording air-pollutant levels.Bird 1968 Using the SCS API, the city adopted an air-pollution alert system with three stages of alert, matching increasingly severe levels of pollution with corresponding counteractions. The city announced its only first-stage alert in 1966; second- and third-stage alerts were never reached. + New York's SCS API alert system in use in 1966The New York Times 1966aSanderson 1977 44 Alert level Measurements SCS API Required conditions to trigger alert Counteractions SO2(ppm) CO(ppm) Smoke(Millions of particles per cubic foot mppcf) First-stage alert 0.7 10 7.5 39 [50] Total SCS API exceeds 39 for four hours and the Weather Bureau predicts the inversion will last another 36 hours. Although 39 was the "official" SCS API level required to trigger a first-stage alert, 50 was set as the level actually used in practice. The city government would ask residents to voluntarily reduce their fuel consumption and car use. Second-stage alert 1.5 20 9.0 68 Total SCS API exceeds 68 for two hours. The city would ban the use of fuel oil, sets a cap on industrial emissions, and asks New Yorkers to stop all transportation—on a voluntary basis—unless essential. Third-stage alert 2.0 30 10.0 90 Total SCS API exceeds 90 for one hour. The city would impose mandatory "brownout" conditions, placing a curfew on lighting and heating and curtailing all but "essential" transportation and industry. Braverman later admitted that the "emergency" alert level of 50 SCS API had been chosen on an essentially arbitrary basis. After the department determined the average level of smog in the city was 12, Braverman said, No one knew what to do next... so I just said, "If it's four times as high, that's an emergency."Reeves 1966a Another defect of the SCS API alert system was that it relied on a balance of multiple pollutants but would disregard fatal levels of any one pollutant under certain conditions. Critics pointed out that the index could have potentially allowed the city to reach lethal concentrations of carbon monoxide without triggering any alert at all, so long as the levels of other pollutants remained low.Reeves 1966a The department acknowledged the SCS API's flaws and later said it had been implemented for lack of a clearly superior alternative. When the system had been adopted, there were no generally accepted standards or best practices for recording air pollution.Reeves 1966a Warnings thumb|alt=Photo portrait of a man looking concerned, with his head resting on his hand.|A task force headed by Norman Cousins (pictured 1976) warned that the pollution in New York City was excessive and "could become a gas chamber" in the wrong weather conditions.Karapin 2016 171 In 1963, Helmut F. Landsberg—a climate scientist with the federal Weather Bureau—predicted that the Northeastern and Great Lakes regions could anticipate a major smog event every three years due to the confluence of weather events and trends like growing population, industrialization, and increased emissions from cars and central heating.The New York Times 1963 In early 1966, Dr. Walter Orr Roberts—director of the National Center for Atmospheric Research—warned of the imminent threat of a smog event with the potential to kill as many as 10,000 people.Wise 1970 5 Roberts identified Los Angeles and New York City as the cities most potentially vulnerable to a large-scale lethal smog in the United States, and further named London, Hamburg, or Santiago as the other most vulnerable cities internationally.Wise 1970 5 Asked if "many" American cities were vulnerable to a disaster smog event, Roberts replied: "Yes. I have been worried that we would wake up some morning to an unusual meteorological situation that prevented the air from circulating and that we might find thousands of people dead as the result of the air they were forced to breathe in that smog situation."Wise 1970 5 The same year, the New York mayor's office established a 10-member task force headed by Norman Cousins (known as the editor of the weekly magazine Saturday Review) to study the problem of air pollution.Kihss 1963 The task force published a 102-page report in May 1963, finding that the city had the most polluted air of any major city in the United States, with a wider range and greater total tonnage of pollutants than Los Angeles.Kihss 1963 The task force criticized the city for lax enforcement of pollution laws, even naming the city itself the biggest violator, with municipal garbage incinerators "operat[ing] in almost constant violation" of its own laws.Kihss 1963 The report warned "all the ingredients now exist for an air-pollution disaster of major proportions"Kihss 1963 and that the city "could become a gas chamber" in the wrong weather conditions.Karapin 2016 171 A July 1966 report by the New York Academy of Medicine Committee on Public Health cautioned that New York City's air-pollution problem made it susceptible to acute, lethal episodes. The academy recommended a reduction of air pollution.New York Academy of Medicine Committee on Public Health 1966 594 Further, their report cautioned that it was unlikely scientists had identified every harmful pollutant in the air or the full range of health effects that could be caused by air pollution.New York Academy of Medicine Committee on Public Health 1966 613–614 Timeline of smog event Air quality measurements, November 19–30 The following charts show the daily mean values of sulfur dioxide, carbon monoxide, and smoke measurements in New York City from November19–30, 1966.Charts are adapted from Fensterstock Fankhauser 1968 18, 27, 32.

In November 1966, New York City was experiencing an unseasonably warm "Indian summer".Popkin 1986 27 A cold front from Canada brought clean air to the city on November19, but the cold front was held in place by pressure from the higher atmosphere.Loory 1966 An anticyclonic temperature inversionAnderson 1999 472—in other words, a warm, mostly stationary air mass located atop a cooler air mass—formed over the East Coast on November 20.Fensterstock Fankhauser 1968 3 Unlike atmospheric convection—the ordinary process of lower, warm air rising—inversions leave cooler air suspended below warm air, preventing the lower air from rising and trapping airborne pollutants that would ordinarily disperse in the atmosphere.Sullivan 1966 Such weather events are common, but they are usually followed by a strong cold front that brings an influx of clean air and disperses pollutants before they have enough time to become highly concentrated; in this case, a cold front approaching west through southern Canada was delayed.Fensterstock Fankhauser 1968 7 When explained in less formal terms, the process of an inversion causing a smog event has been compared to a lid that holds in pollutants or a balloon that fills with pollutants.For a usage of the "lid" analogy, see Sullivan 1966; for the "balloon" analogy, see Loory 1966. In general, smog events occur not because of a sudden increase in a region's output of pollution, but rather because weather conditions like stagnant air prevent the dispersal of pollutants that were already present.Fensterstock Fankhauser 1968 1 The inversion prevented air pollutants from rising, thereby trapping them within the city.Anderson 1999 472 The smog event itself started on Wednesday November 23, coinciding with the beginning of the long Thanksgiving weekend.Popkin 1986 28 The material sources of the smog were particulates and chemicals from factories, chimneys, and vehicles.Popkin 1986 27 Sulfur dioxide levels rose and smoke shade—a measure of visibility interference in the atmosphere—was two to three times higher than usual.Anderson 1999 472 thumb|upright=3.0|center|alt=Refer to caption.|These weather maps show winds at 18,000 feet from November 2126, 1966.

November 24: Thanksgiving Day 5 emWe were flying at about two thousand feet, through a curiously greasy-looking and pervasive haze. The ground could just be made out below—cars, roads, houses, all dim but visible. 5 emThen we began to climb. In less than a minute the ground had vanished. Cars, roads, houses, the very earth itself had been blotted out. We were circling in bright sunlight, above an apparently limitless bank of opaque, polluted air. The smog extended to the horizon in every direction. At a distance, the slanting rays of the sun gave it a coppery, rather handsome appearance. Nearer at hand it merely looked yellow and ugly, like nothing so much as a vast and unappetizing sea of chicken soup. William Wise describing his view from an airplane delayed in landing at John F. Kennedy International Airport. Wise was returning from London, where he had been researching the 1952 Great Smog of London.Wise 1970 4 40% right 1 The city chose not to declare a smog alert on Thanksgiving Day, but The New York Times later reported that city officials had been "on the verge" of calling an alert.The New York Times 1966a Austin Heller, the city's commissioner of air pollution control, said he nearly declared a first-stage alert between 6 a.m. and 10 a.m. on November 24.close Another spokesperson for the city clarified Heller's comments to the press, noting that the required pollution levels for a first-stage alert were not reached at any time that morning and the Weather Bureau's forecast at the time had predicted the inversion would pass in only 24 hours, not the 36 hours required to trigger an alert. Heller, said the decision had been a "very, very close" one.The New York Times 1966a Heller said the index had reached a high of 60.6–10 points higher than the "emergency" mark—between 8 and 9 p.m., and the 60.6 reading was possibly the highest in the city's history.The New York Times 1966a After a nighttime lull, Heller cautioned, the smog would likely spike again in the morning.The New York Times 1966a The unusually heavy smog was evident to the crowd of one million onlookers at the Macy's Thanksgiving Day Parade.Popkin 1986 28 Tabloids and newspapers that ordinarily ran front-page stories about the parade instead carried stories about the smog.Popkin 1986 28 Health officials cautioned those with chronic lung diseases to stay indoors and advised patients that symptoms of pollution-related illness usually lagged 24 hours after exposure.The New York Times 1966a That day, the city closed all 11 of its municipal garbage incinerators.The New York Times 1966aStradling 2010 207 Energy companies Consolidated Edison (called ConEd for short) and Long Island Lighting Company were asked to burn natural gas rather than fuel oil to minimize the release of sulfur dioxide;The New York Times 1966a both companies voluntarily cut back emissions, with Con Ed reducing its emissions by 50 percent.Bigart 1966 The city told 18 inspectors "to forget their turkey dinners and start looking for dirty air," and they issued an "unusually high" number of citations for emissions violations, including two for Con Ed plants.Bigart 1966 Representative William Fitts Ryan of Manhattan sent a telegram to Secretary of Health, Education and Welfare John W.

Many had headaches that were not the product, they thought, of holiday over-eating. Their throats scratched. But no deaths were attributed to the smog...

When asked for comment about the smog he had missed, Lindsay replied "I thought I took all the bad weather with me to Bermuda. It rained there more than half the time."The New York Times 1966cBigart 1966 The announcement "was believed to be the first appeal ever made to New York's citizens in connection with a smog problem".Popkin 1986 28 Conrad Simon, who acted as a liaison between the scientific and political communities during the crisis, later said "We came close to closing the city down."Popkin 1986 28 Pollution was not as high in New Jersey or Connecticut as in New York, but it was still significant. New Jersey reported what was then its worst-ever smog. Elizabeth, New Jersey had smog at half the levels of New York City. A Connecticut health official reported air pollution four times higher than average, but the impact in Greenwich, Connecticut was considered minimal. The nearby New York counties of Nassau, Suffolk, and Westchester reported very little smog.Bigart 1966; Chicago Tribune 1966. Although not part of the area covered by the alert, unusually high smog was reported as far as Philadelphia, Pennsylvania and Boston, Massachusetts,New Bedford Another smog-related story was reported in New Bedford, Massachusetts. Visibility there reportedly became so bad that two burglaries, one at a jewelry store and another at a liquor store, were said to have exploited the thick smog throughout the city as cover. After the burglaries, police officers patrolled businesses door-to-door that day.The Desert Sun 1966 whose mayor issued a similar health warning.The Desert Sun 1966 The alert was declared upon the advice of the Interstate Sanitation Commission. Members of the commission had been monitoring the smog situation in shifts for three days, nonstop. Thomas R. Glenn Jr., the commission's director and chief engineer, recommended the alert at 11:25 a.m. after seeing instruments in New York and New Jersey that showed carbon monoxide greater than 10 ppm (parts-per-million) and smoke greater than 7.5 ppm, both for more than four consecutive hours.Kaplan 1966 In New York, the city asked commuters to avoid driving unless necessary, and apartment buildings to stop incinerating their residents' garbage and turn heating down to 60 °F (15 °C).Bigart 1966 New Jersey and Connecticut asked their residents not to travel, and to use less power and heat.Bigart 1966 Although it was a workday, traffic was light in New York City.Bigart 1966 A check on 303 buildings of the New York City Housing Authority later found near-total cooperation with the city's requests. Private residences were believed to have had a high rate of voluntary cooperation with the city's plea to cut energy consumption.Schumach 1966 The weather forecast called for the heat inversion to end that day, followed by a cold wind that would disperse the smog.Bigart 1966 Nevertheless, Heller said that if the wind did not come, a first-stage alert would likely remain in effect and it might become necessary to declare a second-stage alert if conditions worsened.Bigart 1966 November 26: cold front arrives "Commissioner Heller Announces Lifting of Air-pollution Emergency" (November 26, 1966) — press conference with Commissioner Heller announcing the end of the alert.

The cold front that would blow away the smog was forecasted to arrive between 5 a.m. and 9 a.m.Schumach 1966 Shortly after 9 a.m. the wind arrived, moving mostly from the northeast between 6–10 miles per hour and bringing cooler temperatures in the 50s °F (10–15 °C).Schumach 1966 Glenn at the Interstate Sanitation Commission sent a message advising the alert to end at 9:40 a.m., based on weather and air readings.Kaplan 1966 Shortly after noon, Governor Rockefeller declared the end of the alert; New Jersey and Connecticut also ended their alerts that day.Schumach 1966 Health effects from the smog were downplayed in most early reports. Some hospitals reported increased admissions of patients with asthma.Bigart 1966 An official at the city Department of Health noted that some hospitals were receiving fewer asthma patients, and attributed the reported increases to ordinary random fluctuations.Bigart 1966 The official told The New York Times that "[i]n not one [hospital] is a pattern emerging which would suggest we are dealing with an important health hazard as of this moment."Bigart 1966 By this time, the inability to incinerate garbage had generated a large amount of excess waste. Hundreds of sanitation workers worked overtime to transport garbage to landfills in the Bronx, Brooklyn, and Staten Island,Bigart 1966 with the bulk going to Fresh Kills in Staten Island.Stradling 2010 207 Impact The atmosphere of New York was bombarded with more man-made contaminants than any other big city in the country—almost two pounds of soot and noxious gases for every man, woman, and child. So great is the burden of pollution that were it not for the prevailing wind, New York City might have gone the way of Sodom and Gomorrah. John C. Esposito Vanishing Air (1970)Esposito 1970 204 (cited by Bernstein 1996 294). 40% right 1 Initial estimates of health effects and casualties It was not initially clear to the medical community how many casualties and illnesses had been caused by the smog—or indeed, whether the smog had caused any casualties at all. The population of the area affected by the smog has been estimated at 16 million.Bernstein 1996 294 A November26 story by Jane Brody in the New York Times cautioned that it would likely take "a month or more" before investigators had enough data to assess whether the smog had caused any deaths.Brody 1966 Three days later, after studying admissions to municipal hospitals for cardiac and respiratory complications, the city commissioner of hospitals Joseph V. Terenzio told the press "I can report almost with certainty that there was no detectable immediate effect on morbidity and mortality because of the smog. ... It now seems unlikely that final statistical analysis will reveal any significant impact on the health of New York City's population."Reeves 1966b Early reports of injuries focused not on respiratory damage, but on car or boating accidents caused by poor visibility.Popkin 1986 27 Nonfatal health effects were difficult to measure in the smog's immediate aftermath.Brody 1966 Some of the health effects were themselves delayed; for example, most of the serious effects on the elderly population would only manifest days after initial exposure.Brody 1966 A study on the smog's nonfatal health effects was published in December 1966. The study, conducted by a nonprofit health research group, found that 10percent of the city's population had developed some negative health effects from the smog, including symptoms like stinging eyes, coughing, wheezing, the coughing-up of phlegm, or difficulty breathing.The New York Times 1966d The director of the research group said anything serious enough to adversely affect as much as 10 percent of the population, like the smog had, indicated the existence of a serious public health problem.The New York Times 1966d Subsequent estimates of casualties The earliest report of casualties came in a special message by President Lyndon B. Johnson sent to Congress on January30, 1967. In the message, the president said 80 people had died in the smog.Johnson 1967 Johnson did not cite a source for that claimed estimate of deaths, and there is no known source concluding that 80 people died other than those citing Johnson.80deaths Johnson's source for a death toll of 80 is not clear, but the figure is sometimes repeated (see, for example, its use in Bernstein 1996 294, a biography of Johnson), even after the publication of more-reliable scientific medical papers on the subject. Legal scholar Arnold W. Reitze, who used Greenburg's figure in a scholarly law review article, noticed the discrepancy among sources. Reitze noted "fatality figures concerning episodes are based on statistical techniques and vary among data reporting sources."Reitze 1999 699 , see fn. 155 Two major medical studies have analyzed the extent of casualties from the smog. Leonard Greenburg—the same medical researcher who had previously published findings on the death count of the 1953 and 1963 smogs—published a paper in October 1967 showing that the previous year's smog had likely killed 168 people.Bird 1967d Greenburg showed that there were 24 deaths in excessmortality of how many would normally be expected at that time of year every day, over a period of seven days—using a period four days longer than the smog itself had lasted because of the delay between smog exposure and resultant health effects.Bird 1967d Greenburg said that his analysis could not account for damage during the smog that would remain latent and continue to cause disease and death for years.Bird 1967d The results of Greenburg's paper were reported by The New York Times.Bird 1967d The smog was compared to the 1948 smog in Donora, Pennsylvania, and the 1952 Great Smog of London, both of which lasted five days.Alden 1966 The London smog's death toll of 4,000 was far higher than Donora's, but the smog in Donora was far more severe; at the time of its smog, Donora was a small industrial town with a population of only 13,000 and its population was proportionally hit much harder than London's, with 20 deaths and smog-related illnesses among 43 percent of the population.Alden 1966 Pollution experts estimated that if a smog event as powerful as Donora's had occurred in the much more populous New York City, the death toll could have been as high as 11,000 with four million ill.Alden 1966 Urban life and smog urban decay white flight environmental justice environmental racism thumb|alt=An industrial plant, with a mess of household trash items strewn haphazardly on the ground in front of it.|The incinerator plant at Gravesend Bay in Brooklyn, 1973. The 1966 smog demonstrated the interconnected nature of seemingly disparate problems of urban life, such as waste management and pollution. The smog brought into focus the interrelation of environmental problems and other, complex facets of urban life.Stradling 2010 207 By chance, several conditions happened to prevent the smog from reaching its fullest potential strength.Karapin 2016 171; Popkin 1986 29. Since the event began over the long Thanksgiving weekend, not the workweek, many factories were closed and far fewer commuters were in traffic than normally would be.Popkin 1986 29 The unseasonably warm weather reduced the need for central heating.Popkin 1986 29 On November25, the high of 64 °F °C broke the previous record high for that date, leading the reporter Homer Bigart to describe the apartment-heating restrictions as "no problem" for residents.Bigart 1966 These mitigating factors meant that pollutant levels—as well as the ensuing death toll and other adverse health effects—were likely lower than they could have been in less favorable conditions.Popkin 1986 29 Attempts by city government to react to the smog had unintended negative side effects. As Mayor Lindsay reflected in his 1969 book The City, "[e]very time you shut down an incinerator, you increase the amount of garbage on city streets."Stradling 2010 207 Efforts to address a given environmental problem can cause undesired side effects, sometimes unforeseeable, and often related to a city's limited resources.Stradling 2010 207 Environmental harms in general are linked to urban decay and social inequality. After the 1966 smog, the task of reducing air pollution became an essential part of the municipal government's goal to make "the city attractive again to the middle class and acceptable to all its residents."Stradling 2010 207 Such harms—but especially those that generate obvious and unpleasant effects, as smog does—were among many factors that motivated and exacerbated white flightwhiteflight The term "white flight" refers to the historical mass migration of white, typically middle-class Americans from urban areas into their surrounding suburbs, especially in the mid-to-late 20th century. from American cities, including New York City, in the mid-20th century.Stradling 2010 207 The mass migration of affluent residents—motivated at least in part by environmental harms like chronic smog—drained the city's tax base and resulted in an economic loss of human capital.Stradling 2010 207 Residents who remained in the city often lacked the financial resources that would have enabled them to move somewhere else, even if they had wanted to flee the unpleasant environment and health hazards caused by pollution.Stradling 2010 207 The burdens of that pollution—including the direct effects of pollution itself, indirect effects (such as uncollected garbage in the streets), and other problems stemming from lack of municipal resources after white flight—became "emblems of larger governmental neglect and social inequality" to those residents.Stradling 2010 207 Political reaction National attention The smog is commonly cited as one of the most-visible and most-discussed environmental disasters of the 1960s in the United States, alongside the 1969 Santa Barbara oil spill and the 1969 Cuyahoga River fire.Benton-Short Short 2008 39; Harper 2016 229; Horowitz 2005 189–190. National public awareness of the smog and its health effects spurred the nascent environmental movement in the United States and galvanized support for legislation to regulate air pollution.Reitze 1999 699; Podhora 2015 24–25. Vernon McKenzie, chief of the air pollution division of the federal Public Health Service, called the smog "a warning of what can happen—and will happen—with increasing frequency and in wider areas unless something is done to prevent it."Reeves 1966b In the 1968 book Killer Smog, William Wise warned that the 1966 smog and the 1952 London smog represented a vulnerability to air pollution disasters among American cities: Perhaps, as in Great Britain, change will begin to come only after a large-scale tragedy. The conditions are favorable for one in any of a dozen of the nation's most populous cities. A mass of still air drifting slowly eastward, an intense thermal inversion, and then five, six, seven days of increasingly poisonous smog. The air will look bronze, almost copper-colored, as it did during New York's 1966 Thanksgiving smog. ... From every appearance, a similar tragedy is now being prepared in America—and there is very little time left in which to prevent it.Wise 1970 208 At the time of the smog event, only half of the urban population of the United States lived with local protections on air quality; the smog event catalyzed the call for federal regulation on the issue.Podhora 2015 24–25 Spencer R. Weart of the American Institute of Physics said the American public "did not take the problem [of air pollution] seriously" until the 1966 smog.Weart 2014 According to Weart, an important factor driving awareness of the smog was its location, as events in New York "always had a disproportionate influence on the media headquartered there."Weart 2014 Municipal response right vertical John Lindsay NYWTS 1.jpg Refer to caption.

Only the outlines of far buildings can be seen, with details like windows or architectural features impossible to distinguish. Smog in May 1973. By 1972 New York City had cut levels of sulfur dioxide and particulates by half from their peak.Popkin 1986 29 Before the 1966 smog, the city government had been slow to act to regulate air pollution.Millones Schumach 1969 Despite general awareness of the health and environmental impacts of smog, other problems took priority: as The New York Times reported, issues like "housing, crime, education and keeping the city 'cool' were at the forefront of city government concerns."Millones Schumach 1969 But the 1966 smog impelled a swift response by the city government,Karapin 2016 172; Sieckhaus 2009 72. who now felt pressure to respond "in the aftermath of disaster."Millones Schumach 1969 Lindsay, then a liberal Rockefeller Republican, had run as a supporter of stronger air pollution control in his 1965 mayoral campaign, and the 1966 smog reinforced Lindsay's position on the issue.Karapin 2016 172 City Council member Robert A. Low, a Manhattan Democrat and chairman of the city subcommittee on air pollution, criticized Lindsay for failing to enforce an air-pollution bill that had been passed in May.Sibley 1966 The bill, authored by Low, would update city incinerators and require apartment buildings to replace their incinerators with other garbage disposal methods.Sibley 1966 Low accused Lindsay's administration of "dragging its feet" on the problem of air pollution,Sibley 1966 which Lindsay called a "political attack."Reeves 1966b The mayor's office prepared a report in the aftermath of the smog, singling out the coal-burning Consolidated Edison company, city buses, and apartment building incinerators as significant contributors to air pollution.Karapin 2016 172 The report noted that the change in weather that dispersed the smog "spared the city an unspeakable tragedy," and that if New York City had stagnant smog at the high levels commonly found in Los Angeles, "everyone in the city would have long since perished from the poisons in the air."Weisbrot Mackenzie 2008 214 Consolidated Edison began using a fuel with lower sulfur content, and by June 1969 the city had reduced the level of sulfur dioxide in the air by 28percent.Millones Schumach 1969 In December 1966, the New York City Administrative Code section on pollutant levels in the air was strengthenedPopkin 1986 29 by a bill that was later described as the "toughest air pollution control bill in the country" at that time.Sieckhaus 2009 72 Lindsay announced a plan to install 36 new stations for the Department of Air Pollution Control to measure air pollution levels throughout the city—an upgrade from the sole station in the Harlem Courthouse building. The stations would send data to a central computer using telemetry to create a profile of the city atmosphere.Schumach 1966; Kaplan 1966. Five of those stations would also send data to the Interstate Sanitation Commission.Kaplan 1966 The city purchased a computer system and equipment from the Packard Bell Corporation for $181,000 ($US-GDP 181,000 1967 in US-GDP dollars).The New York Times 1967a In November 1968, the city opened 38 monitoring stations, 10 outfitted with computer equipment. The 10 computerized stations were designed to send data every hour to the central computer, while the other 28 operated manually as backup.Bird 1968 The old index system used during the 1966 smog, which produced a single number from multiple measurements, was abandoned as simplistic and unhelpful.Bird 1968 The new index system was similar in that it used weather forecasts and measurements of pollutants in the air and had three progressive stages of severity ("alert," "warning," and "emergency") requiring stronger actions by city, industry, and citizens.Cohen Shy Benson Riggan 1971 542–543 The city's actions mitigated air pollution and reduced the likelihood of a major smog event on the same scale.Millones Schumach 1969 In contrast to dire warnings from the mayor's air-pollution task force in its May 1966 report, a city official said in 1969 "[w]e probably have the possibility of a health catastrophe under control now."Millones Schumach 1969 The city declared minor smog alerts in 1967 and 1970;The New York Times 1967b; Bird 1970. conversely, a four-day inversion similar to the Thanksgiving weather of 1966 occurred in September 1969, but it passed without incident—neither smog nor deaths resulted.Popkin 1986 29 Norman Cousins, chairman of the mayor's task force, credited the regulations enacted since the 1966 smog for the prevention of a comparable September 1969 event. Cousins wrote in a message to Lindsay: New York City's air is cleaner and more breathable today than it was in 1966. ... It is important to ask what would have happened on those days [in September 1969] if the pollution levels had continued to worsen at the same rate of deterioration that occurred from 1964 to 1966. The answer is that there could have been a substantial number of casualties. The fact that an episode did not occur attests to the capability of the City's programs to protect its air resources.Popkin 1986 29 After the passage of strict new state and federal air regulations, the city passed its updated Air Pollution Control Code in 1971, designed in part to address concerns that nitrogen oxides and unburned hydrocarbons had been left insufficiently controlled by the previous changes.Popkin 1986 29 By 1972, New York City had cut levels of sulfur dioxide and particulates by half from their peak.Popkin 1986 29 According to an article published by the EPA Journal in 1986, those improvements at the city level were "the legacy of concern that emerged after the 1966 Thanksgiving Day smog disaster."Popkin 1986 29 States' responses thumb|alt=Refer to caption.| Following the 1966 smog, air-pollution control became a major policy objective of both Nelson Rockefeller (left), the Republican Governor of New York, and Lyndon B. Johnson, the Democratic president. Before 1966, air-pollution control had largely been the responsibility of states and political subdivisions of states like counties and municipalities (cities and towns).Freeman 2005 175–176; Goklany 1999 26; see also Goklany 1999 22 , Figure 1–3 (a bar graph showing the number of municipal, county, and state air-pollution programs from 1880–1980). The federal government played little role in air-pollution control, and to the extent that it did, its actions supported the efforts of states and local governments.Goklany 1999 26 For example, federal law provided resources like research, training, grants to improve state and local programs, and a conference procedure to convene agencies and polluters under the guidance of the Department of Health, Education and Welfare.Goklany 1999 26 Direct regulations—such as, for example, setting emissions standards—were left to states.Goklany 1999 26 The governors of New York (Rockefeller), New Jersey (Hughes), Delaware (Charles L. Terry Jr.), and Pennsylvania (Raymond P. Shafer) met in December 1966 to address air pollution in their region.The New York Times 1966e Each governor pledged to enforce their state's pollution abatement laws and to prevent their own state from becoming a "pollution haven" with lax regulations to attract industry.The New York Times 1966e At the same meeting, the governors also discussed the possibility of new tax incentives to motivate industry to reduce pollution and the creation of a new interstate compactinterstate compact In American law, an interstate compact is an agreement between two or more states, often to create a new regional governmental agency. Article I, Section 10 of the Constitution requires the approval of Congress before any interstate compact can take effect. to set industry standards, which would require adoption by all member states and approval by Congress.The New York Times 1966e Those four states were already members of the Delaware River Basin Commission (DRBC), an interstate agency that controls water pollution in the Delaware River.Bird 1967d The proposed air-pollution compact was modeled after the DRBC and would function similarly, setting minimum air standards across states and enabling enforcement actions against polluters.Bird 1967a New York, New Jersey, and Connecticut adopted the proposed Mid-Atlantic States Air Pollution Control CompactSullivan 1967 with the possibility for Delaware and Pennsylvania to join in the future.Edelman 1968 565 Its approval by Congress became a policy goal of Rockefeller's failed primary bid for the 1968 Republican presidential nomination.The New York Times 1968 The compact was never approved by Congress and thus never took effect.Edelman 1968 565 After the 1966 smog, "the consequences of state inaction were apparent to the naked eye," public outcry intensified, and the demand for federal intervention increased.Goklany 1999 175–176 New Jersey passed several new air-pollution laws in 1967.Sullivan 1967 Nevertheless, traffic and drifting polluted air from New Jersey remained a major contributor to New York City's pollution problem.Millones Schumach 1969 Edward Teller—the physicist known for his role in developing the hydrogen bomb and an advisor to Mayor Lindsay on pollution and energy issues—advocated for New York state to adopt stricter sulfur fuel standards than the city.Bird 1967c A leader of the advocacy group Citizens for Cleaner Air criticized the local and state governments at a state public hearing, calling the city's enforcement "in a state of collapse" and, saying the city acting alone "cannot or will not enforce any standard or rule," demanded that the state government increase its role.Millones Schumach 1969 Perhaps the most notable critic of New York's inaction was Robert F. Kennedy.Bird 1967b On a 1967 tour of pollution sources, Kennedy—then a New York Senator and soon to embark on his 1968 presidential campaign—criticized the city, the states of New York and New Jersey, industry, and the federal government for their failures to adequately address the problem.Bird 1967b Kennedy warned, "[w]e are just as close to an air-pollution disaster as we were last Thanksgiving."Bird 1967b In Kennedy's view, the solution would have to come from the federal government, as state and local agencies lacked the ability or oversight for the task.Bird 1967b Federal response Air pollution control, already a priority of President Lyndon B. Johnson's administration,EnviroJohnson Johnson signed legislation in 1965 to establish new standards for automobiles by 1967.Bernstein 1996 293 In May 1966, Johnson signed an executive order that directed the heads of all federal agencies to plan the installation of air pollution controls at federal facilities.Bailey 1998 120 Joe Califano, Johnson's Secretary of Health, Education, and Welfare, organized a task force in 1966 to prepare a report for the 90th Congress on issues of environmental concern, primarily air pollution. The task force's report was published November 21, 1963—just days before the New York City smog.Bernstein 1996 264 became a greater concern after the smog. By early 1967, his statements on air pollution became more rhetorically urgent.Blomquist 2004 599 In January 1967, Johnson sent a message to Congress entitled "Protecting Our National Heritage," the first section of which was entitled "The Pollution of Our Air" and focused on the problems posed by air pollution.Johnson 1967 The message was prompted by wide public discussion of the problem following the 1966 smog.Reitze 1999 700 Johnson cited the experiences of specific American cities and towns in the message, and highlighted the 1966 smog at length: Two months ago, a mass of heavily polluted air—filled with poisons from incinerators, industrial furnaces, power plants, car, bus and truck engines—settled down upon the sixteen million people of Greater New York. For four days, anyone going out on the streets inhaled chemical compounds that threatened his health. Those who remained inside had little protection from the noxious gases that passed freely through cooling and heating systems. An estimated 80 persons died.80deaths Thousands of men and women already suffering from respiratory diseases lived out the four days in fear and pain. Finally, the winds came, freeing the mass of air from the weather-trap that had held it so dangerously. The immediate crisis was ended. New Yorkers began to breathe "ordinary" air again. "Ordinary" air in New York, as in most large cities, is filled with tons of pollutants: carbon monoxide from gasoline, diesel and jet engines, sulfur oxides from factories, apartment houses, and power plants; nitrogen oxides, hydrocarbons and a broad variety of other compounds. These poisons are not so dramatically dangerous most days of the year, as they were last Thanksgiving in New York. But steadily, insidiously, they damage virtually everything that exists.Johnson 1967 y thumb|alt=Refer to caption.|President Johnson signing the Air Quality Act of 1967. The law, a series of amendments to the 1963 Clean Air Act, was enacted in response to the 1966 smog. Johnson called for a bill regulating toxins in the air and increasing funding for pollution programs.Johnson 1967Weisbrot Mackenzie 2008 214 Edmund Muskie, a Senator from Maine and political environmentalist, praised Johnson's words, pledged to hold hearings on the proposals,Frankel 1967 and would soon sponsor the Johnson administration's bill, which became the Air Quality Act.Reed 1967 Muskie also co-sponsored bills in 1967 for research on non-polluting automobiles using either electric or fuel cell technology.Blomquist 2004 610–611 While discussing the research bills on the Senate floor, Muskie said "the serious air pollution situation in New York City [in November 1966] dramatically illustrated what our cities may be facing in the future if an alternative to the [internal] combustion engine is not developed."Blomquist 2004 610–611 Congressional interest and public pressure for greater air pollution regulation had existed since the signing of the 1963 Clean Air Act, the first federal legislation on the issue, but further action had been opposed by members of Congress who believed responsibility for air regulation properly lay with the states, not the federal government.Bailey 1998 119 Partly in response to the added public pressure spurred by the smog event, Congress passed and Johnson signed the 1967 Air Quality Act, which amended the 1963 Clean Air Act to provide for study of air quality and control methods.Bailey 1998 125; Barnhill 2011 66. The Air Quality Act was a significant advancement in the realm of air-pollution regulation, but one that was ultimately ineffective. In Train v. Natural Resources Defense Council, Inc., a 1975 decision by the Supreme Court of the United States, Justice William Rehnquist summarized the law's effect as follows: The focus shifted somewhat in the Air Quality Act of 1967, 81 Stat. 485. It reiterated the premise of the earlier Clean Air Act 'that the prevention and control of air pollution at its source is the primary responsibility of States and local governments.' Its provisions, however, increased the federal role in the prevention of air pollution, by according federal authorities certain powers of supervision and enforcement. But the States generally retained wide latitude to determine both the air quality standards which they would meet and the period of time in which they would do so. The response of the State to these manifestations of increasing congressional concern with air pollution was disappointing. Even by 1970, state planning and implementation under the Air Quality Act of 1967 had made little progress.Train v. Natural Resources Defense Council, Inc., 421 U.S. 60, 64 (1975). Among contemporaneous critics, John C. Esposito—an environmentalist and affiliate of Ralph Nader—wrote the 1970 book Vanishing Air to accuse Muskie of watering down the bill and adding needless complications to satisfy industry.Esposito 1970 270, 273; see also Marcello 2004 51–52. A 2011 encyclopedia of environmental law article judged that the act "was a failure but it was the first step in federal air pollution control."Barnhill 2011 66 Calls for greater air pollution regulation in this era culminated with the passage under President Richard Nixon of the 1970 Clean Air Act, which supplanted the Air Quality Act and has been described as the most significant environmental legislation in American history.Bailey 1998 119 The 1970 Clean Air Act significantly increased the role of the federal government and, for the first time, imposed air quality requirements on states.See Train v. NRDC, 421 U.S. at 64–65. The 1966 smog in cultural memory The most widely recognized legacy of the 1966 smog was the political reaction to it, which galvanized the nascent environmental movement in the United States and prompted demand for sweeping air-pollution control laws.Benton-Short Short 2008 39; Harper 2016 229; Horowitz 2005 189–190; Reitze 1999 699; Podhora 2015 24–25. The smog has been remembered for various purposes by scientists, historians, journalists, writers, artists, activists, and political commentators. Compared to the September 11 attacks thumb|alt=Refer to caption.|A plume of smoke rising from lower Manhattan after the September 11 attacks, seen from space. Cumulative air pollution events like the 1966 smog contrast with the sudden pollution that resulted from the September 11 attacks. The full range of negative health effects arising from the September 11 attacks came to light in the years following the attacks. The 1966 smog serves, along with the earlier major New York City smog events in 1953 and 1963, as a precedent used for comparison with the air effects caused by the collapse of the World Trade Center. The 1966 smog and other historical smog events differ from the September11 pollution in significant ways that limit their usefulness as a point of comparison. Prior New York City smog events were chronic, cumulative, and caused by thousands of small sources, while the air impact of the September was sudden, intense, and the result of a single culpable source. The absence of prior events similar to the September11 attacks left "a hole in the medical library," and presented medical experts with a challenge in the absence of "hard knowledge about the health consequences of intense brief pollution."Johnson 2002 Compared to 21st-century smog in China thumb|left|alt=Several skyscrapers shrouded in a thick cloud of smokey gas.|The 1966 New York smog served as a historical precedent for air pollution in China in the 2010s (pictured is Beijing in early 2013). Other major air pollution, particularly in China, has been compared to the 1966 smog. Elizabeth M. Lynch, a New York–based legal scholar, said that images of visible air pollution in Beijing from 2012 were "gross" but not "that much different from pictures of New York City in the 1950s and 1960s", specifically referring to the 1952, 1962,1963smog and 1966 smog events.Lynch 2013 Lynch wrote that the Chinese government's increased transparency on the issue was an encouraging sign that pollution in China could be regulated and abated, just as it had in the United States.Lynch 2013 Similar comparisons between the 1966 smog and Chinese pollution in late 2012 appeared in Business Insider and Slate.Spector 2013; Yglesias 2013. USA Today cited the 1966 smog after China issued its first "red alert" air quality warning in December 2015;Szabo 2016 the same month, an article in The Huffington Post used the 1966 smog to argue that China could follow the United States' model to regulate pollution.Kaufman 2015 In pop culture right "Smog Almost Killed New York City, Here's How" (March 24, 2017) — interview with photographer Arthur Tress and history of air pollution in the United States.

Club interpreted the writers' use of the smog as a symbolic representation of the character Betty, who spends the episode "longing to enter [Don Draper's] apartment and tear some shit up""hover[ing]" and "waiting to poison it from within".St. James 2012 The New York City-based indie pop band Vampire Weekend used a photograph of the smog over the city skyline, taken by Neal Boenzi and originally published in The New York Times, for the cover of their 2013 album Modern Vampires of the City.Battan 2013 After the election of Donald Trump Following the 2016 election of Donald Trump to the presidency, his administration's environmental policy—which included steep budget cuts to the EPA and deregulation—prompted several reflections on the environmental condition of the United States before the creation of the EPA. Articles published by The New York Times,Dwyer 2017 Vice Media's tech-news site Motherboard,Byrne 2017 public radio station WNYC,Garfield Gladstone 2017 real-estate news site 6sqft,Cohen 2017 and the Natural Resources Defense Council (NRDC) environmental advocacy groupPalmer 2017 connected Trump's declared policy agenda to a risk of returning to a more polluted environment, with each publication evoking the 1966 smog as an example of the potential dangers of defunding and deregulation.
