Ancient Indians who lived in the Southwest accurately forecast the occurrence of global warming over 12,000 years ago, scientists at the General Delivery University announced today.

"With remarkable accuracy, the ancient Indians who lived near what is modern day Phoenix, predicted massive climate change over 10,000 years BCE," said Emil Howlry, dead of the GDU School of Archeology and Pot Hunting.

The world 12,000 years ago looked much different than today's world, said Howlry.

"Most of North America down to about Iowa was covered in a giant sheet of ice, and sea level was about 300 feet lower than it is today," Howlry added. "A land bridge connected Siberia to Alaska."

"The climate of central and southern Arizona looked more like Colorado, with lots of running water and grassy plains," he added. "The desert as we know it today didn't exist."

But the ancient Indians saw change coming.

"The ancient Indians anticipated that the massive glaciers were going to melt, sea level was going to rise, and in general the climate was going to get hotter and drier for the next 10 or 20 thousand years," Howlry added.

"The ancients noticed that glaciers in the mountains north of Phoenix and Tucson started to melt.  "They extrapolated that the big ice sheets farther north we also going to melt, flooding the world."

"Turns out their forecast was spot on," he added. "They forecast global warming."

Ancient writing suggest that 10,000 years ago, blame for the climate change was mostly placed people offending their gods.

"Ancient people thought they had offended the gods, so the weather turned hostile to them," said Howlry. "The ancients assumed they had caused the global warming which was melting the ice."

Variations of climate change being people's fault is also found in the Noah and Flood stories which abound around the world.

"Something seriously bad happened around 10,000 years ago and people assumed it was their fault," said Howlry.

As late as 1,000 years ago, climate change was still impacting prehistoric residents of Arizona.

"We had the Hohokams living in central Arizona, and they were wiped out due to changes in the climate such as extended drought," said Howlry. "According to our sources, blame for this was placed on neighboring Indian tribes such as the Apaches."

Howlry noted that even  modern Phoenix could also fall to the effects of continuing climate change. "This time people will probably blame the Republicans in the state legislature if Phoenix runs out of water due to climate change,' said Howlry.

Today, the continuing change of global climate to even warmer and drier regimes is again being blamed on humans.

"Whatever is going wrong, it must be the fault of humans" said a spokesman for People Against People On Earth, a group wanting to reverse most of the last 3 centuries of technological advancement to reduce carbon emissions into the atmosphere.

"Humans presume maybe more than they are actually responsible for," noted Howlry. "Climate change is the only is either always getting warmer, or always getting colder out there. Look at the record of the last million years...sometimes there are ice ages, and sometime not."
