Bob Watson Discusses Large-Scale Systems Transformation, His Life in Science Assessment, and the Need for Trust in an Anti-Science Era

Global science assessment goes far beyond crunching numbers and tallying up abstract human impacts: it is about convincing the world to act. Recalling his life in leadership with co-hosts Kai Chan (professor and Canada Research Chair at UBC) and Maia O’Donnell (UBC graduate in soil science and producer of the Small Planet Heroes podcast), Robert (Bob) Watson narrates his path from early training in atmospheric chemistry to high-stakes positions at NASA, the White House, and chairing organizations like the Intergovernmental Panel on Climate Change (IPCC) and the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Bob reveals how speaking up for the environment means rising above politics. Yet confronting so many unknowns, including corruption and intense disparities in power, access, and resources, is often at great personal cost.

In the quest for transformative systems change, Bob reminds us that seeking a consensus while tackling massive problems means making sense of a lot of noise. Much of it is negative, even paralyzing. He asks us instead to answer, whether with our phones, wallets, or simply more open minds, the call for a more grounded, evidence-based, and mindful future for everyone.
