If you have or are planning to have a family, you should likely be thinking about just this already on a personal and family level. Do what you can to reduce your footprint, but also do your long-term planning based on expectations of climate change.
Among other things, don't buy property within anything considered 100-year or possibly even 500-year flood zones - climate change may mean that 100-year zones start getting flooded every 10 years or less, and that's not only going to impact you directly but the economics of recovery because you and all your never-expected-to-flood neighbors will be trying to recover.
Also consider how the climate is expected to change over the next 50 years where you're considering settling - and what impact it'll have if it changes faster than that.
