What if some of the places we think are thousands of miles apart are not quite as far apart as we have been taught?
We interpret weather systems, geography, migration, oceans, and even seemingly unrelated natural events through a particular picture of the Earth. But historical maps have not always shown the continents the way our modern maps do, and today’s coastline does not necessarily represent the full landmass beneath the water.
In this Author’s Notes conversation, Lula Starling is not trying to prove that one particular old map is correct. The question is what happens when we stop assuming the modern map is the one part of the conversation that cannot be questioned.
What would Saharan dust look like if the journey were shorter than we think? What might submerged land change? Why could one cartographer depict the world so differently only nine years apart? And what if some events look disconnected simply because of the map we are using to understand them?
Maybe the map we know is right.
But what if there is another possibility?
This episode is speculative inquiry, not an attempt to establish an alternative geographic model as fact. Historical and scientific material is used to explore the questions, not to prove that unrelated events share a cause.

Library of Congress — Martin Waldseemüller Maps
1507 Universalis Cosmographia and 1516 Carta Marina
The Library of Congress notes that the 1507 map depicted a separate Western Hemisphere and Pacific Ocean, while the later Carta Marina reduced the New World, eliminated the Pacific from the depiction, and showed North America joined to Asia.
U.S. Geological Survey — Florida Basement Geology
USGS research identifies the ancient basement beneath Florida as including the Gondwanan Suwannee terrane with West African origins.
NOAA — Saharan Air Layer
NOAA tracks Saharan dust traveling across the Atlantic and reaching the Caribbean, Florida, Central America, and during stronger outbreaks, Texas.
Recent weather context
The August 2026 Nepal/Tibet flooding and Grand Canyon flash flooding were among the recent events that inspired the broader question explored in this episode. They are not presented as evidence that the events shared a cause.
