https://solarsystem.video/videos/watch/d53942d3-d878-4e88-a43e-cc421dd596aa Meet Dr. Colleen Golja, atmospheric scientist working at the intersection of chemical engineering and climate research, visiting ISSI as part of a Working Group on stratospheric processes. Listen to Colleen as she traces her path from an early fascination with chemical engineering and energy systems to a growing concern about climate change that pulled her toward atmospheric science. She explains why the stratosphere, and the ozone layer within it, matters so much. Colleen walks us through the discovery of the ozone hole and one of the most successful international environmental agreements ever adopted. She describes her own work piecing together satellite measurements of ozone, water vapour, wind, and temperature, and highlights the value of her ISSI Working Group. Beyond the science, Colleen reflects on returning to ISSI for a second time, this time in the warmth of a Bernese summer and closes with a note of hope.
