Pythons Will Colonize U.S.

Global Warming Will Make Southern States More Habitable

Python habitat will grow dramatically as the U.S. warms up over the next century, according to a new U.S. Geological Survey and National Parks Service study.

"Burmese pythons — an invasive species in south Florida — could find comfortable climatic conditions in roughly a third of the United States according to new 'climate maps' developed by the USGS," the agencies reported. "Although other factors such as type of food available and suitable shelter also play a role, Burmese pythons and other giant constrictor snakes have shown themselves to be highly adaptable to new environments."

The maps tell the story:
