Extreme weather events — from hurricanes and floods to increasingly severe heat waves — not only kill thousands globally; they damage critical infrastructure, force displacement, and imperil the livelihoods of millions. At the same time, our capacity to understand these risks has expanded dramatically. Global datasets from satellites, sensors, and crowdsourcing, together with advances in AI weather forecasting and earth-science foundation models, are creating unprecedented capabilities to identify vulnerable populations, anticipate hazards, and understand the resilience of the built environment. Yet greater technological capability does not automatically produce better decisions or more resilient communities. Join our teams at Harvard and NYU to explore what we are learning from developing and deploying global digital public goods for the climate crisis — and the governance and decision frameworks needed to translate new data and technologies into responsible, effective public action THE SESSION IN TWO PARTS 1. Lessons from building digital public goods Lessons learned from developing digital public goods for the climate crisis. Drawing on practical experience with remote sensing, crowdsourcing, and AI — including the teams behind FloodNet, Heat Risk API, and ReadyMapper — we examine what has worked, what remains difficult, and how global datasets can complement local knowledge to build climate-data infrastructure as a genuine public good. 2. Closing the data-to-action chasm From data to action: closing the data-to-action chasm responsibly. We examine the emerging funding, governance, stewardship, and decision frameworks needed to connect digital public goods more directly to public action — addressing accountability, access, sustainability, local capacity, and social legitimacy. THE GUIDING QUESTION How do we build the institutional and governance infrastructure that enables digital public goods to lead to better decisions — and ultimately better climate outcomes?
