Geography: The major continents are the same as in our timeline. The main differences are in Australia, Southeast Asia and the Americas.
- The northern coast is partially flooded, so the Gulf of Carpentaria is slightly larger and extends farther into Australia than in our timeline.
- As such, Australia is wetter than in our timeline.
- New Guinea is shorter north to south.
- In addition, the Cape York Peninsula is slightly narrower than in our timeline, due to higher sea levels, and the islands in between Australia and New Guinea are smaller.
- Due to higher sea levels, there are more islands than in our timeline, though some are completely flooded.
- Similar to Oceania, much of Southeast Asia has been flooded by higher sea levels.
- The Mekong River Delta lays to the northeast of its present location due to higher sea levels, and Tonle Sap is a bay rather than a lake.
- Indonesia has a more irregular coastline, with more fjords, bays and inlets.
- Due to the higher sea levels, Southeast Asia has supported a sedentary fishing community for centuries as well as some of the world's most lucrative trading routes. While the islands can support permanent human populations or agriculture, their economies are primarily supported by trade and fishing due to excellent fishing grounds and their strategic location.
- The Bohai Sea in Northeast China is larger and extends farther into the North China Plain.
- The Indus and Ganges river deltas are submerged.
- The Caribbean islands are restricted to Cuba, Jamaica, Puerto Rico, and Hispaniola. All the others are either submerged or just barely above sea level.
- Half of the Yucatan Peninsulas and most of Florida are submerged underwater.
- Louisiana is partially submerged, with a narrow bay in place of the Mississippi river.
- The Andes Mountains, the Rockies, and the Mexican highlands are connected, forming a massive mountain range that extends from Alaska south to Chile. This provides a massive North-South highway for alpine flora and fauna to move across the Equator, allowing the human cultures that depend on them to migrate as well, making for a much more connected Americas, accelerating technological advancement and increasing their resilience to colonization.
- The Gulf of Sindra is slightly larger and extends into the desert, increasing average humidity, supporting a larger farming community.
- The Nile Delta is farther south than in our timeline due to higher sea levels.
- The eastern half of the north plain of Italy is partially submerged.
- Italy retains the characteristic boot-shaped spur in the south, though the southern tip is virtually an island.
