Climate change is the preeminent problem of the 21st century. Why not address it with 21st century solutions? While still in development, advances in data science — specifically around big data and AI — offer new and valuable tools for climate adaptation. How is this being deployed and who is leading the charge? In the Season 3 premiere of ClimateReady, we are joined by Paul Fleming, Corporate Water Program Manager for Microsoft (microsoft.com/environment). We discuss some of the reasons why a company known primarily for computer software is leading groundbreaking developments for water management related to climate change. Paul discusses the potential for big data and AI with respect to utilities and smarter water management. We also hear about the CEO Water Mandate initiative (ceowatermandate.org) and the expanding role of the private sector in addressing the century’s greatest environmental and sustainable development challenges. Following our main interview, we introduce a new segment to the show. Underlying all of our work around climate adaptation is a sense of optimism. We can (and must!) create more resilient systems and societies. To support this idea, we are featuring short personal reflections about a “Climate of Hope.” The episode closes out with a story from Nureen Anisha, an AGWA Research Fellow and graduate student, speaking of efforts in her native Bangladesh that give her hope for the future.
