|15400 AD Ice Age|
|Average Temperature||-102° F|
|Temperature Change||-161° F|
|Areas Affected||The whole world|
The Great Ice Age Of 15,400 AD was the worst in Earth's history. It lasted 19 million years. Record bone chilling average temperatures of -102° F was felt across the globe.
Around 15,363 AD cold water currents blocked the warm tropical water from getting to the poles. Over the next 37 years global temperatures plummeted to -28° F. By the end of that century the ice age had truly begun. Glaciers 1.7 miles thick came from the polar regions. They reached to about 7.0° N and and 6.7° S latitudes.
During the beginning to middle of the ice age 67% of the human population perished. During the peak of the ice age global temperatures were at -102° F, effectively the only creatures that survived without much impact were polar bears, penguins, and other animals that had warm layers of fur or feathers. 88% of all reptiles became extinct due tothe extreme cold. By 19,014,981 AD the ice age finally ended, but not without of making 81% of the human population perish.
