Season 1, Episode 5 — Bob McDonald on curiosity, climate, and communicating science
Science enters public life through communication long before it reaches governments or policy debates. In this conversation, Bob McDonald, chief science correspondent for the CBC and longtime host of Quirks and Quarks, reflects on more than five decades spent translating scientific discovery for public audiences.
Drawing on a career shaped by the Apollo era, environmental reporting, and rapid technological change, McDonald discusses how public understanding of science has evolved alongside growing political polarization, climate misinformation, and distrust in expertise. He argues that science communication is less about simplifying information than about helping people connect scientific evidence to everyday life.
The conversation explores climate change, pseudoscience, artificial intelligence, energy transitions, scientific literacy, and the role of curiosity in shaping how societies respond to uncertainty and technological change. McDonald also reflects on optimism, public engagement, and why science journalism still depends on trust.
