Dealing with Uncertain Futures:Climate Change Vulnerability in the TRV
• There is uncertainty associated with both the marine and riverine drivers, as will as the interaction between the two
• However, it is possible to envision plausible futures under different scenarios associated with changing riverine and marine drivers
Implications
• El Niño conditions provide a snapshot of a potential future
• Still investigating impacts and causes
• TJR mouth rarely closes, but when it does there can be major impacts
• Highlights importance of long-term monitoring, real-time data access, and rapid management response (USFWS and City of IB)
