If the Romans start mining coal and other minerals because gunpowder makes blasting easier, global warming will kick in earlier and we'll get some changes.
Higher sea levels will give us
1. Suez Straits, for easier travel to India and the Far East.
2. Karelian Straits, for easier travel along the Siberian coast.
3. Volga Straits, for easier travel to the Caspian Sea.
4. Antarctic Archipelago.
5. Greenland Archipelago.
6. Warmer Siberia, for European expansion along the coast and up the rivers.
7. Warmer Canada, for Amerind expansion down the rivers to the islands.
8. Warmer Iceland, for Cod fishing, pasture, and lumbering.
9. Lots of flooded lowlands for good fishing, such as
a. Mississippi Sea at the conjunction of the Missouri, Mississippi, and Ohio.
b. Amazon Sea, west of the Manaus Straits.
c. California Sea, east of the Carquinez Straits.
d. West China Sea, west of the Shantung Archipelago.
e. Plata Sea, up to the Parana river.
f. Bengal Sea, up to the falls of the Brahmaputra, dividing India and Asia.
g. Baltic Passage, from the Rhine to the fjords of Norway, east to Muscovy.
h. Khmer Sea, to the falls of the Mekong.
i. Orinoco Passage, around the Guiana Archipelago.
10. Lots of accessible mountains and hills next to the ocean, which gives us
a. Lots of mining next to the ocean.
b. Lots of waterfalls next to the ocean.
c. Lots of little agricultural areas isolated from other areas by mountains.
11. Warm weather gives us expansion of malaria into Europe and consequent demographic decline of northerners till enough thalasemia and sickle cell genes build up to reverse the decline.
12. Increased trade because the Northern passage will open sooner or later, first along the Siberian coast, then across the Bering Straits to the Americas. Figure on syphillis and trichinosis making it to the Old World, and Malaria, Alcoholism, and childhood epidemics making it to the New World with consequent demographic declines for the next few hundred years till enough disease resistant European genes can spread among the natives.
13. New World and Old World crops spread out. Potatos, Cassava, Corn, Sweet Potatos, Peanuts, Beans, Squash, Chilis, Sunflowers, etc.
So what happens to the Roman empire when the population of the north explodes with the new warm lands, and their population collapses as the malaria mosquitos moves north?
