Ah, I remember back when idiots thought climate change meant the world would be under water. Turns out it actually means a lot less water will be available.
Edit: i just went to check how my country is doing water wise:
Germany is one of the regions with the highest water loss worldwide. Since 2000, the country has lost 2.5 cubic kilometres of water per year. In the years 2019 to 2021, record low groundwater levels below the long-term lowest groundwater levels were recorded at the measuring points in many places.
Some areas will be under more saltwater than now, like Florida and the Netherlands. Some areas will be inhospitable due to consistent heat and lack of FRESHwater like Mexico, Northern Africa, India, etc.
There is also a mix: salty water that won't submerge land permanently, but that will reach more and more inland across rivers during high tides. River Mekong comes to mind, along which rice is cultivated and that already now suffers from this phenomenon. Salty water on land means you will not grow anything there anymore.
The Mekong delta produces rice that is used to feed an incredibly high number of people in Asia.
In Brazil there was a mega flooding in the south recently, I knew some people there and they said it felt very apocalyptic. This is most definitely not normal climate.
Also they found some arid (like desert arid) zones recently in Brazil for the first time. It used to be semi-arid.
