A reconstruction of mean surface temperature in the northern hemisphere over the past two millennia based on high-resolution proxy temperature data (white curve), which retain millennial-scale variability, together with the instrumental temperature record for the northern hemisphere since 1856 (black curve). This combination indicates that late twentieth-century warmth is unprecedented for at least roughly the past two millennia for the northern hemisphere. (Climate Chnage in Prehistory)

The Mayan civilization flourished on the immense lowland, limestone shelf forming the Peten-Yucatan peninsula that thrusts out into the Gulf of Mexico. Here the climate is hot, and in the south very wet during the rainy season of May to October. The northern region of the peninsula is much drier, requiring the Maya to excavate and construct thousands of underground, bottle-shaped cisterns. (The Mayan Prophsies for 2012)

North America

In some prehistoric periods the Southwest was wetter than it is today, but for most of the last ten thousand years the Southwest has usually been at least as hot and dry as it is today, and there were short periods of extreme drought. (Patterns in Prehistory)


A description of Antarctica, published in 1992 (more than twentyfour centuries later), offers a strikingly similar geographic account. “The most conspicuous physical features of the continent are its high inland plateau (much of it over 10,000 ft.), the Transantarctic Mountains . . . and the mountainous Antarctica Peninsula and off-lying island. The continental shelf averages 20 miles in width (half the global mean and in places it is non-existent).” Like Atlantis, Antarctica rises high above sea level. Indeed, it is the highest continent in the world. (Atlantis Beneath the Ice)
