In a recent Eos article ( 87 (3), 27, 2006), Broecker and Stocker criticize Ruddimaris [2003] hypothesis of an anthropogenic origin to the Holocene carbon dioxide (C0 2 ) rise. Broecker and Stocker note the analogy between the Earth's orbital configuration 400,000 years ago and the current configuration by aligning the EPICA Community Members [2004] ice core record for the deglaciation that occurred 430,000–420,000 years ago, with the last deglaciation (20,000–10,000 years ago). Considering that the two situations are analogous, it appears that no glacial inception, marking the end of the Holocene, should have occurred by now.
