Found this tidbit in the Environmental Leader daily about a study conducted by the European Project for Ice Coring in Antarctica (EPCIA).

The original article was from Reuters:

"OSLO (Reuters) - Greenhouse gases are at higher levels in the
 atmosphere than at any time in at least 800,000 years, according to a
 study of Antarctic ice on Wednesday that extends evidence that mankind
 is disrupting the climate.

 
 
 Carbon dioxide and methane trapped in tiny bubbles of air in ancient
 ice down to 3,200 meters (10,500 ft) below the surface of Antarctica
 add 150,000 years of data to climate records stretching back 650,000
 years from shallower ice drilling.

 
 
 "We can firmly say that today's concentrations of carbon dioxide and
 methane are 28 and 124 percent higher respectively than at any time
 during the last 800,000 years," said Thomas Stocker, an author of the
 report at the University of Berne.

 
 
 Before the Industrial Revolution, levels of greenhouse gases were
 guided mainly by long-term shifts in the earth's orbit around the sun
 that have plunged the planet into ice ages and back again eight times
 in the past 800,000 years." More.
