Climate Extremes and Urgent Choices with Sonia Seneviratne
Episode 4
In this episode, Chris sits down with Sonia Seneviratne, climate scientist, professor at ETH Zurich, and a leading voice in climate extremes. From her early fascination with astrophysics and childhood astronomy books to pivotal moments in the Amazon rainforest and now shaping global climate assessments, Sonia's journey is one of curiosity turned into environmental responsibility.
What drives Sonia's work is a deep commitment to fact-checking reality and speaking truth at the intersection of science and society. Together, we explore her path from physics and biology to environmental science, her role as a coordinating lead author and bureau member of the IPCC - and Vice Chair of the IPCC's Working Group I - she sees herself as both a teacher and a "climate doctor." This is a powerful and inspiring conversation about truth, responsibility, and the urgent choices before us.
