Canary in a Coal Mine

Written by Bob Sundstrom
This is BirdNote.
['Going to the Mine' - Bob Fox and Benny Graham in How Are You Off for Coals]
For at least 75 years, miners in Great Britain carried a live canary in a cage every day as they went down into the mines.

So, how did this practice start? Miners began using canaries in 1911, based on the advice of Scottish scientist John Haldane. He reasoned that a singing bird would be a good indicator of carbon monoxide — the gas can build to deadly levels in mines, and it has no smell. When a canary began to weaken, or stopped singing, miners knew to get out of the mine — and quickly.
But why use a bird as an alarm instead of, say, a mouse? Haldane understood a bird's breathing anatomy. And he knew that as birds breathe, they get a dose of air both as they inhale and as they exhale. Compared to mice — or to miners — canaries would get a double dose of toxic gases. Their reactions served as an early warning of danger.
The little birds with the big song served alongside British miners until 1986, when more humane electronic warning devices replaced them.

Like the rest of Sydney, I've spent the past month or so choking through a haze of hazardous smokey particulate matter. I am lucky by comparison. Communities, care workers and emergency responders have directly faced the fire's consequences. Some of which have lost their lives trying to help. The rest of us have been left with a strange set of daily challenges; how to buy the right face masks, dealing with toxic indoor air, handling commitments to people, work and school. It feels strange to try to celebrate the traditional holiday season when so many have lost so much.

Throughout all of this, I keep thinking about canaries. You've heard the cliche; ‘canary in a coal mine.' The phrase stems from a mining safety tradition of carrying canaries down into deep sub-surface mines. Though from a modern perspective it was an inhumane practice, the canaries' ill health was a crucial urgent sign that the mine's air was no longer safe.

A favourite of mine for several years now, Lady of Mine is the self-funded, independently-released 1989 debut LP by self-taught Italian-American musician Joe Tossini. After only owning a poor-quality digital version of the album, I was astounded to discover that Lady of Mine had been reissued two years ago. (redirected from canary in a coal mine) canary in a/the coal mine Something or someone who, due to sensitivity to his, her, or its surroundings, acts as an indicator and early warning of possible adverse conditions or danger. Refers to the former practice of taking caged canaries into coal mines.

Canaries, like many birds, have a complex respitory cycle. Due to the demands of flight and thanks to some rather ingenious adaptions, they gather oxygen from the air during both inhalation and exahaltion. This makes them especially sensitive to the effects of gasses, including toxic gasses like carbon monoxide. Though it might be odourless and invisible, carbon monoxide gas is a deadly poison, which causes rapid suffocation and leaves a telltale red flush. Canaries are more likely to display ill effects sooner than the humans carrying them.

The idea to use canaries may have been courtesy of the chemist John Haldane. Famous for experimenting on himself with the effects of deadly gases, he noted both the effects and identified the likely cause of carbon monoxide poisoning. He suggested using birds in mines due to their uniquely sensitive respitory cycle. If canaries have anyone to thank for their predicament, it is Haldane.

The ability to detect danger quickly has consequences. Just ask Gordon Clark. The last time he saw his father was on 24 September 1939, just before his father, James Clark, walked up to work at the Glen Afton mine in New Zealand. Unbeknowest to Gorden or his father, a weekend fire had led to dangerous levels of carbon monoxide in the mine which would go on to kill eleven people, including James Clark. It was around this time that we began to see canaries. As quoted from the archives of the New Zealand Herald:

The canary in the coal mine mac os 11

'Tiny cages holding finches, canaries and budgerigars were .. taken into the shafts as the rescue parties entered.' (Quoted from: The Waikato coal mining disasters that killed 54 men in two Septembers)

'Many of the men who went below owed their lives to them, for toward seven o'clock tonight searchers were confronted with increasing waves of carbon monoxide, detected only by the collapse of the birds they had brought with them.' (Quoted from: The Waikato coal mining disasters that killed 54 men in two Septembers) Angels that kill (itch) mac os.

The phrase, 'canary in the mine' has become a hallmark of an early warning that something is not right in our context. This is especially true when dealing with something that we can't easily detect with our own senses; something that is too small, like fine particulate from fires, or too large and distributed, like the effects of climate change.

Though all thinking may be subject to some bias or another, we owe it to ourselves to try to agree on the best impartial evidence as a basis for decision making. This way, we aren't basing crucial decisions on the vagaries of social, economic or political forces. So the quesiton remains: In the case of our current experiences, what level of evidence should cause us to worry that there is something serious going on? Is it the hottest recorded average day in Australia? The largest fires? The longest run of polluted days in recorded New South Wales history? Maybe all of these. Maybe none of these.

In England, it took until 1989 for miners to stop using canaries as evidence for toxic air. New electronic ‘noses' were developed instead. That's the thing about evidence; as we develop new science and technology, we can upgrade our criteria for what counts as good evidence. Though it might have been good enough once to rely on stories and memories of hot summers, it might be better now to rely on actual historically recorded temperature data and the mathmatics to analyse it. Slapfest! mac os. We might once have accepted the evidence of our noses and eyes, whether the air looked and smelled okay. Now, it might be better to use the evidence from our atmospheric measuring instruments.

Carefully selecting the right evidence can be hard. Psychologically, we're better at dealing with threats that we can see and understand, directly in front of us in space and time. It makes it hard to worry much about evidence that imply longer-term risks when we are busy worrying about if the air is safe enough for our children to play outside today. That's what makes choosing the right evidence so important. In our effort to deal with the present, we don't want to miss the evidence that tells us about dangers that lurk in our many possible futures. If we miss the evidence, then we may miss our opportunity to innovate the way we live now, before it's too late. Just ask the canary.
