Join the Hyperthesis hosts as we speak with our guest Emma MacNeil, an air quality scientist measuring point source emissions in Nova Scotia. Before we delve into air quality monitoring, we discuss the El Niño Southern Oscillation (ENSO) cycle, which is currently leading to record high global temperatures. Before ending with a story about the discovery of oxygen, we take an in-depth discussion with Emma about measuring the air quality of different production facilities, and what exactly affects air quality and how it is measured.
