The ocean and river mouths contain very many important resources for societies to ignore. --- > rise will be slow enough that no one's going to drown. It depends on the solution: the cheapest usually is to build seawalls, and this obviously puts the city at greater risk of flooding. --- The comment you're replying to states rising sea levels as an example. There are, of course, known consequences that you don't address. To name two, it is a very direct consequence that 1) the weather will get more violent, with the additional amount of energy it contains, leading to a more frequent occurrence of natural disasters. Next, a change in climate will cause a massive redistribution and likely destruction of land suitable for agriculture, as well as lower overall quality for agricultural land, thereby 2) threatening worldwide food security.
