What's wrong with migration? People do that anyway when they move out of their parent's house and into their own, often in another city. You describe storms becoming more frequent, which is something insurance companies will see a mile away and increase premiums or refuse to provide cover for. That will reduce the value of property in those areas and property buyers will go further inland instead. It sounds like some poor property investor might be left holding the bag if he doesn't sell his coastal city building in time. Instead of feeling sad for his loss, perhaps trust that he knows what he's doing and will sell it in time so the migration happens gradually and for incremental economic reasons rather than as a sudden emergency. Your energy argument doesn't add up. Increasing the thermal energy of everything in a system doesn't make it able to do more work (violent storms). Storms are driven by heat flowing from hot to cold. Not from hot to also-hot. If you show that temperature differences between parts of the ocean/atmosphere are going to become more extreme, then more severe storms would make sense. That could be caused by cold things getting colder or hot things getting hotter.
