Climate change, which is the most serious problem of our age and future, and indirectly kills more and more people every year, continues to show itself even in unpredictable places. Climate change has become so tangible that scientists have recently announced that even the smell of snow has changed due to climate change.
Clinical neuroscience professor Johan Lundstorm, who introduced himself as an ‘odor researcher’ from the Monell Chemical Sense Center in the USA, explained that the smell of snow reflects the pollution in the air. Stating that especially the upper layer of the snow mostly takes compounds from the air, Lundstorm stated that some molecules in these compounds hit the nose harder than others.
So how does climate change change the smell of snow?
The explanation that fully links this relationship to climate change was made by Parisa A. Ariya from McGill University. Ariya stated that the circulation and density of air molecules increase with the warming of the land and air. For this reason, he stated that climate change affects how snow smells.
Ariya said the snow serves as a “snapshot of an atmospheric process,” meaning it directly reflects everything that happens in the air. The research conducted by the scientist in 2017 showed how the pollution from the gasoline engine exhaust is absorbed by the snow. The worst part is that this pollution was transferred to the water and soil as the snow melted.
