Centennial-scale changes in the global carbon cycle during the last deglaciation
Description: The underlying processes responsible for a rise in atmospheric carbon dioxide levels at the last glacial termination remain uncertain. This paper presents high-resolution carbon dioxide and methane records of the last deglaciation from the West Antarctic Ice Sheet Divide ice core. The authors find that a significant proportion of the direct radiative forcing associated with the rise in atmospheric carbon dioxide during the last glacial-interglacial occurred in three abrupt steps during approximately four centuries.
