Really interesting reading - looks like there's a lot of comments here along the lines of things that could be done to build more fire/flood/huricane resistant housing.
I don't want to detract away from those points, but it's definitely worth saying that, at present, we're polluting CO2 into the atmosphere at a very large and to some extent avoidable rate. Climate change is already happening, but the extent to which it happens is still down to us - we can and need to do lots to improve flood resistance in, say, Florida, but we can also stop parts of Florida ending up below sea level too.
