For example with rising sea levels the damage estimates are based on property value assumed to drop to zero in places that would be covered by a rise.
But what actually happens is that we can build structures which cost orders of magnitude less than all that property values to keep the water out of those places.
And it’s not just speculation. People actually do build such structures, and extract economic value from places below sea level.
These models that talk about damages assume a total loss of value to all points below new sea level. Doesn’t match how things actually play out in reality.
