The greatest challenge facing humanity is climate change. One of its most serious consequences is sea-level rise. The rise of the oceans can be monitored by satellite, a global technology for a global problem. NASA and domestic and international partners have constructed a satellite system to carry out this task. Who has collaborated? Who has not? Why? Because this system is about climate change, NASA and its allies have had to navigate through turbulent political waters. This presentation will draw lessons learned for collaborative governance.
