I have not yet, however, seen any such research on consensus for the effects of climate change. Is there a large, documented consensus on any estimate of sea level raise?
My point was that real estate market prices are much more heavily influenced by current conditions, and current demand, rather than hypothetical future conditions. The price elasticity of demand has little to do with whether the buyer believes that the property will flood in future decades due to climate change. Someone who wants a beachfront mansion is probably going to buy it for close to the same price whether or not s/he believe it will still be there in 50 years, just as s/he might buy an expensive car that will similarly degrade and need expensive maintenance exceeding the original purchase price over time.
If we are talking about the US then there's government flood insurance.
If you still believed what was once the consensus, you would believe in some crazy stuff. Science is skeptism of the consensus, not the other way around.
Much waterfront property is _already_ vulnerable (and expensive to insure) today, regardless of whether you believe in consensus climate science, due to storms and flooding in current climatic conditions. That house by the ocean is going to destroyed at some point, the only question is when and how.
