These predictions don't even take into account factors like sea level rising by meters. Think about the demographic impact of coastal infrastructure going underwater and having to be rebuilt and reconnected to different roads and railways, farmland going underwater and permanently lost, many million of people becoming homeless also in first world countries, lack of food and clean water. Help yourselves to add more to the list. If enough of this happens fertility rates are the least of the problems.
