More often, yes, but not continuously in any one area. The planet is a big place and while I don't doubt a lot more of our resources will need to go into dealing with the costs of increased natural disasters including reduced capacity to produce food, it's hard to see this affecting everywhere all at the same time. More likely is that entire areas become gradually unable to support a modern economy and comfortable lifestyle forcing mass relocations (some of which may well be to areas that are currently "underpopulated" due to currently inhospitable climates or even reserved wilderness parks etc.).
