We are going to have a housing crisis and more because of climate change and people moving from places where temperatures are unbearable and the weather is more unstable.
Feel free to post a link to one concrete case of mass migration due to human climate change from temperatures or rising sea levels. Not ambiguous cases like the hurricane in your link but actual relatively demonstrable cases of direct temperature rises or sea level rises from climate change caused by humans. So far, a lot of frantic hand waving and heady speculation aside, I know of none.
There are lots of articles if you want to read more, for example: https://www.sciencenewsforstudents.org/article/climate-chang...
