Today is the anniversary of the Great Smog. What happened in 1952 changed Britain forever. A terrible smog developed which lasted for a week, beginning on December 5th 1952. It killed probably 12,000 people. The hospitals, the emergency services, the mortuaries, the funeral parlours had more work to do than during the Blitz or the Cholera epidemics. Higher deaths than normal were still occurring as late as January 1953.
A temperature inversion kept a blanket of cold damp air over London. This stoped the pollutants being dispersed and blown away. But post-war austerity (this time introduced by the Labour Party) made it such a killer. Britain was exporting our top grade coals. And allowing domestic users to use terrible stuff called ‘nutty slack’. This was sludge, dust, and fragments of very low grade and therefore very smokey coal. 18% of the coal used was domestic, but it contributed 60% to the emissions. The fog was yellow and sulphuric. Public Transport had to be halted as no one could see beyond their hands in front of their faces. People had to leave cinemas because no one could see the screens.
What changed Britain was that it finally persuaded people that coal-polluted air was a killer. People had debated it since the Victorian period, but did very little about it, some even believing smoke was good for you. In World War II the government encouraged smog near Cities, to cloak the industrial areas from the Luftwaffe Bombers. After 1952, it was clear what a killer smog was. In 1956, the Clean Air Act established zones where only smokeless fuels could be used. Polluting industries were dispersed from the towns. Taller chimneys were used. This eventually cleared up the problem.
Pollution still killing people
Job done, or so we all thought. Dr Gary Fuller (see below) tells us that we are incapable of dealing with more than one pollution threat at a time. In 1962, another smog, created by sulphur dioxide pollution, killed perhaps 1,000 people in London. And London still has a lot of air pollution, not just from traffic fumes, and it is still killing people.
Traffic pollution in London is being dealt with more aggressively by the current Mayor. Partly as a response to a brave coroner who found that a 9-year-old girl, Ella Kissi-Debrah, died because of air pollution. (girls-death-contributed-to-by-air-pollution-coroner-rules-in-landmark-case). The London Mayor began addressing the issue by first creating and then expanding, the Ultra Low Emission Zone, to encompass all the London Boroughs. This has been very controversial as it has meant many people having to sell cars that do not meet the standard. This had the unfortunate byproduct which was that it enabled the unpopular Conservative Party hanging on, by the skin of their teeth, in Boris Johnson’s old constituency.
The creation of Local Traffic Neighbourhoods are another front against diesal pollution. They allow local authorities to introduce traffic reduction methods by blocking off many neighbourhood roads from through traffic. These have been fought tooth and nail by its opponents. But have been a success, cutting local pollution.
Freedom from Air Pollution?
But much less well known are other threats. For example, there is an increasing threat from trendy wood burning stoves which are very polluting. I very reluctantly decided to install a diesal heater in my narrowboat as it is less polluting that a cosy Wood Burning Stove. Yet their sales are soaring as people seek ways of mitigating soaring post-Ukraine war electricity prices.
Agriculture is very polluting too, with fertiliser, and manure mixing with urban pollution to create dangerous particulates. It turns out that the most polluting time of the year is not Autumn, nor Winter but Spring because of this agricultural activity.
Listen to the BBC’s excellent episode of ‘Inside Science: Killer Smog’. If you cannot use BBC Sounds, then go to the link to a Podcast at the bottom of the piece. These are both based on the work of Dr. Gary Fuller of King’s College, London, detailed in his book ‘Air Pollution: The Invisible Killer’.
We need to stop being short-sighted, not just ‘solving’ one problem before moving onto the next. We need a fundamental revision of our systems to allow us to enjoy the last two of the four freedoms so eloquently expressed by Roosevelt (the subject of the 2024 BBC Reith Lectures):
