Compared to the other continents, Africa would lose the least land, but due to increased temperatures, it would become an inhospitable place. Cairo, Alexandria, Dakar, Lagos and thousands of cities would be covered by the seas.
If the ice melts, we could really know what Antarctica looks like. In what is known as the Antarctic Archipelago (eastern part), four fifths of all the world's ice are currently contained, and although it has remained in the last hottest periods, it would definitely not survive an Eocene period. In western Antarctica we find more fragile ice fractions that float on water. As of 1992, the net loss of ice has been about 65 million metric tons per year.
Cities like Shanghai, Beijing, Tokyo, Singapore, Bangkok, Mumbai, Baghdad and Dubai in Asia, which currently have more than 760 million people living in areas, will be completely under water; including several other cities that would also be affected. That is why hundreds of new islands would emerge along the coast of the Pacific and Indian Oceans.
Australia will lose a small piece of land, mainly along the entire coast; But four out of every five Australians will have to emigrate because it is on the coasts where 80 percent of their population is concentrated. Besides, a new lake will emerge in the central part of the island.
Europe will be the continent most affected. London, Amsterdam, Copenhagen and Stockholm will cease to exist, as will Holland and Denmark (and they will have to put aside their eternal fight for the sea). The Mediterranean Sea will grow but the Black Sea and the Caspian Sea will grow twice in size.
As for North America, the major urban centers on the east coast will disappear. The entire Florida peninsula and a good part of Cuba and the Yukatán peninsula will no longer exist. The western coast would not be affected as much as the eastern part, but cities like Seattle, Los Angeles and San Francisco would.
In South America, its northern part will be under water, affecting Colombia, Venezuela, Guyana and Suriname. The basins of the Orinoco, La Plata and Amazon rivers will allow the passage of water extending the Atlantic Ocean. And with the increase in temperature, the Andes area will be affected by modifying the climate of cold cities such as Bogotá, Quito and La Paz.
