FYI,

The two research papers and a summary perspective on the work are  
published in the current issue of Science:

ATMOSPHERIC SCIENCE:
Tiny Bubbles Tell All
Edward J. Brook

Our knowledge of long-term human effects on greenhouse gas levels in  
the atmosphere comes from air trapped in ice cores taken from polar ice  
sheets. These ice core samples allow researchers to place modern  
changes in the context of natural variations over hundreds of thousands  
of years. In his Perspective, Brook discusses results reported in the  
same issue by Siegenthaler et al. and by Spahni et al. based on new  
samples obtained by the European Project for Ice Coring in Antarctica  
(EPICA). The new long records of carbon dioxide, methane, and nitrous  
oxide from EPICA extend the window on greenhouse gas levels to 650,000  
years. The results confirm that the modern atmosphere is highly  
anomalous and reinforce the view that greenhouse gases and climate are  
intimately related.
