Scientists predict that a 0.5 m sea level rise is likely, with more possible. We calculated that about 4,000,000 people would have to move if the sea level rose by this amount. If the sea level rose by even 1/10th this amount, about how many people would likely have to move? (Assume the population is distributed evenly across the affected areas.
