Climate Change circa 6,000 B.C.

Along with death and taxes, the only other constant in life is change.  Now that the Al Gore hysteria of global warming seems to be cooling down a bit  the new climate hysteria mantra has been changed to  let's stop global climate change. 

But the global climate has always been changing as proven once again by a recent discovery published in a scientific journal by famed University of Chicago paleontologist Paul Sereno and his team. 

About 6000-10,000 years ago  
The period of the Green Sahara, as some researchers call it, began when a fluctuation in the Earth's orbit changed African weather patterns and brought more rain to the desert. The lakes that developed supported six-foot-long pike fish, turtles, crocodiles and an array of other wildlife and human settlers.

But the dunes eventually returned, swallowing for ages any record of how Stone Age people managed to thrive at the site in northern Niger.

"It's really the story of humanity's struggle to exist in an environment undergoing severe changes," Sereno said.

Hmmm, 6000 years ago people had already discovered fire but was it this smoke polluting the atmosphere; was this smoke so damaging to the environment to cause the Earth's orbit to change?  Probably not.  Or is it possible that there are other factors beyond human actions which cause climate change such as the change in the Earth's orbit? 

Digging at different locations all across our planet would reveal artifacts such as plants and bones that indicate thousands of years ago these places had a different climate.  In other words it has changed since then; climate has always been changing long before Al Gore noticed it and will continue to do so long after he and his acolytes have moved on to the latest phony crisis. 
And that is a constant.
