The scent of climate change – perfumed ‘polution pods’ on display at COP26 Glasgow

Polution Pods are capturing the smell, quality and exact air temperature in places around the world via geodesic domes at the COP26 forum, where major world leaders are desperately discussing how we can work together to limit the devastating effects of climate change.

On display in Glasgow, where COP26 is currently taking place, it’s hoped that people actually stepping into the Polution Pods will dramatically evoke the conditions people are struggling to live in right now – a brilliant example of how smell can be used to engage all of our senses in artistic and politically provocative ways.

 

 

‘The Pollution Pods are a series of geodesic domes whose air quality, smell and temperature accurately recreate the pollution of five different locations on three continents: London, Beijing, São Paulo, New Delhi and Tautra, a remote peninsula in Norway. Michael Pinsky created the pods in 2017 to test whether art can change people’s perceptions of, and actions around, climate change. Now they face their greatest challenge yet – to shift the debate on air pollution and climate change to help secure real change at COP26.’

The Pollution Pods’ have been travelling to reach as many people as possible with their scented message, their journey beginning in Granary Square, London, then drifting to Birmingham, Lancaster and Newcastle and where ‘accompanied by Ride for their Lives – staff from six UK children’s hospitals who cycled 800km from London to Glasgow to deliver messages from the international health community including the Healthy Climate Prescription Letter, signed by 450 medical organisations across the globe.’

The Pollution Pods have been constructed by students from the University of East London and have been generously supported by the Clean Air Fund with additional sponsorship from Airlabs and BuildwithHubs.

If you’re anywhere near Glasgow, we usrge you to experience the scents in person – it really is extraordinary how smell can allow us to travel immediately, via our noses. Obviously we usually prefer doing this with fabulous fine fragrances that take us to exotic locations and happy holiday memories, but it behoves us all to take climate change seriously, and to appreciatel how scent can be used in more artistic, environmentally important ways. 

 

The Polution Pods will remain on display – FREE to enter – in Glasgow until November 12th, and all details of where and how to experience them can be found at whatsonglasgow.co.uk

Wake up and smell the coral – and climate change?

Caitlin Lawson, a marine biologist at the University of Technology Sydney in Australia, thinks we have a lot to learn about climate change from the smells that coral produce

Having witnessed the annual spawning of coral larvae, which takes place every November on the Great Barrier Reef in Australia, and describing the spectacle as being ‘like an underwater snowstorm,’ – Lawson set about her task of collecting samples of the gaseous (and rather pongy) scent chemicals they release during this orgy of olfaction. Hakai Magazine reported on her research, explaining that ‘Using advanced analytical chemistry techniques, Lawson and her colleagues are working to identify the spectrum of volatile chemicals the corals produce under different conditions. They hope that measuring these gaseous compounds can give them a way to assess the corals’ health.’

Because when you think about it: why do things smell? Why are we so receptive to these scents, and what might we learn by unravelling this secret, sniffable language?

‘All living things release volatile chemicals,’ explains the report, ‘and many species have adopted specific volatiles as communicative signals. Scientists have long studied their function in terrestrial organisms. A plant’s volatile emissions might indicate to nearby flora that an insect predator has alit, for example, or they might be used to attract another species that feeds on that predator. Detecting these chemicals also has medical uses—think of dogs sniffing out cancer or perhaps even COVID-19.’

 

 

But it’s far harder to capture and analyse smells transmitted under water (think baked beans on toast for tea followed by a nice warm bath…) and so Lawson says she and her team ‘are playing catch-up to the terrestrial world,’ when it comes to unravelling the signals living creatures such as the so-endangered coral reefs are trying to tell us.

‘In a recent study’, the report continues, ‘the scientists described how they detected 87 volatile chemicals being dispersed by two species of coral, Acropora intermedia and Pocillopora damicornis.’ A great number of these volatile smells have already been flagged as important to climate regulation, and Lawson believes ‘this is a potentially huge source that, so far, we have overlooked’ when it comes to mapping (and predicting) what’s happening to our climate.

We already know that odours impact people’s social interactions, and sense of inclusion or exclusion from others; and plants signal attack or distress to one another through smell – that’s basically what essential oils are: invisible scent messages whizzing through the air to warn others of their species or deter insects. So, might coral (and other living creatures) send scented signals not only to ring the alarm bell (or perhaps even help warn surrounding creatures of impending danger), but bang the gong for getting it on? Says Lawson: ‘This is still very much in the baby stage of research. There’s so much to explore…’
