Peter Sinclair posted this video on his blog. It has some troubling new information.
We need to develop an action plan to deal with the likely outcome that about 10% of the world’s population will eventually be displaced. Ideally, before it happens. It does happen slowly so there is time to come up with some ideas. The trick will be getting the other 90% to care about those affected by it enough to contribute to finding solutions. The main driver of sea level rise is climate change. Solve that and you could save the lives and property of millions of people around the world.
An idea for dealing with the problem directly would be not encouraging new development along coastlines unless it meets high standards for safety and resiliency. New homes would need to be raised up enough to not be as vulnerable to flooding, and be able to withstand hurricane force winds with ever greater intensity.
