So, let's say scientists started coming out and saying that the damage we've done to the Earth is irreversible and that our sea levels are definitely going to be one meter higher in 40 years, putting several coastal U.S. cities underwater. Wouldn't that dramatically alter the real estate market? And since, we're not really on our way to changing our production/consumption/emission habits, would it be a smart investment to start selling off beach front resorts now (just in case)?
