Detailed Answer: Predicting sea level rise is complex and involves multiple factors, including thermal expansion of water, melting glaciers and ice sheets, and land subsidence. For San Diego specifically, projections vary depending on the emission scenario (how much greenhouse gas we continue to release) and the model used. However, most climate models suggest a significant rise in sea level over the next 50 years. Conservative estimates predict a rise of several inches to over a foot. More aggressive scenarios, where greenhouse gas emissions remain high, could see rises exceeding two feet. These projections do not account for local factors like land subsidence, which could further exacerbate the impact in San Diego. It's important to consult reports from organizations like the IPCC (Intergovernmental Panel on Climate Change), NOAA (National Oceanic and Atmospheric Administration), and the California Coastal Commission for the most up-to-date and detailed projections. These reports often provide ranges, acknowledging the uncertainties inherent in these complex predictions.
Simple Answer: San Diego can expect sea levels to rise between several inches and potentially over two feet in the next 50 years, depending on greenhouse gas emissions and other factors.
Casual Reddit Style Answer: Yo, so sea level rise in SD? It's gonna be a thing. We're lookin' at anywhere from a few inches to maybe even a couple of feet in the next 50 years. Depends on how much we screw up the planet, you know? Check out some NOAA reports if you wanna get nerdy with the details.

San Diego, a coastal city renowned for its beautiful beaches and vibrant waterfront, faces a significant challenge: rising sea levels. Driven by climate change, this phenomenon poses a substantial threat to coastal infrastructure, ecosystems, and the city's economy.
Scientific projections indicate a substantial rise in sea levels along the San Diego coastline over the next half-century. While precise predictions vary depending on the emission scenario and the climate model used, the consensus points towards a significant increase. Conservative estimates suggest a rise of several inches to over a foot. However, more aggressive scenarios, under which greenhouse gas emissions remain high, could result in a rise exceeding two feet.
Several factors contribute to rising sea levels, including the thermal expansion of seawater (as warmer water expands), the melting of glaciers and ice sheets, and even land subsidence in certain areas. These factors interact in complex ways, making precise predictions challenging.
The impact of sea level rise on San Diego will be significant, potentially leading to increased coastal erosion, flooding, and saltwater intrusion into freshwater sources. Proactive adaptation strategies are essential to mitigate these risks. This includes investing in coastal protection measures, implementing stricter building codes, and promoting sustainable land use planning.
The projected sea level rise in San Diego underscores the urgency of addressing climate change. By reducing greenhouse gas emissions and implementing effective adaptation measures, San Diego can safeguard its coastal communities and its valuable natural resources for future generations.
Expert Answer: Based on current climate models and IPCC reports, San Diego is likely to experience a significant sea level rise within the next 50 years, ranging from several inches under conservative scenarios to potentially over two feet in more pessimistic projections. The considerable uncertainty inherent in these predictions necessitates a precautionary approach, prioritizing adaptation strategies and mitigation efforts to minimize the potential impacts on coastal infrastructure and ecosystems. Local land subsidence needs to be considered for more precise regional estimates.
