CO2 lags Temperature changes

Atmospheric Carbon Dioxide Concentration Across the Mid-Pleistocene Transition
(Science, Volume 324, Number 5934, pp. 1551-1554, June 2009)
- Bärbel Hönisch, N. Gary Hemming, David Archer, Mark Siddall, Jerry F. McManus
"The lack of a gradual decrease in interglacial PCO2 does not support the suggestion that a long-term drawdown of atmospheric CO2 was the main cause of the climate transition."
Atmospheric CO2 Concentration from 60 to 20 kyr BP from the Taylor Dome ice core, Antarctica (PDF)
(Geophysical Research Letters, Volume 27, Issue 5, March 2000)
- Andreas Inderm¨uhle, Eric Monnin, Bernhard Stauer, Thomas F. Stocker
"The lag was calculated for which the correlation coefficient of the CO2 record and the corresponding temperatures values reached a maximum. The simulation yields a lag of (1200 ± 700) yr."
Atmospheric CO2 Concentrations over the Last Glacial Termination
(Science, Volume 291. Number 5501, January 2001)
- Eric Monnin, Andreas Indermühle, André Dällenbach, Jacqueline Flückiger, Bernhard Stauffer, Thomas F. Stocker, Dominique Raynaud, Jean-Marc Barnola

"The start of the CO2 increase thus lagged the start of the [temperature] increase by 800 ± 600 years."
Ice core records of atmospheric CO2 around the last three glacial terminations
(Science, Volume 283, Number 5408, pp. 1712-1714, March 1999)
- Hubertus Fischer, Martin Wahlen, Jesse Smith, Derek Mastroianni, Bruce Deck

"High-resolution records from Antarctic ice cores show that carbon dioxide concentrations increased by 80 to 100 parts per million by volume 600 ± 400 years after the warming of the last three deglaciations."
Southern Hemisphere and Deep-Sea Warming Led Deglacial Atmospheric CO2 Rise and Tropical Warming
(Science, Volume 318, Issue 5849, September 2007)
- Lowell Stott, Axel Timmermann, Robert Thunell
"Deep sea temperatures warmed by ~2C between 19 and 17 ka B.P. (thousand years before present), leading the rise in atmospheric CO2 and tropical surface ocean warming by ~1000 years."
The phase relations among atmospheric CO2 content, temperature and global ice volume over the past 420 ka (PDF)
(Quaternary Science Reviews, Volume 20, Issue 4, pp. 583-589, February 2001)
- Manfred Mudelsee
"Over the full 420 ka of the Vostok record, CO2 variations lag behind atmospheric temperature changes in the Southern Hemisphere by 1.3±1.0 ka"
Timing of Atmospheric CO2 and Antarctic Temperature Changes Across Termination III
(Science, Volume 299, Number 5613, March 2003)
- Nicolas Caillon, Jeffrey P. Severinghaus, Jean Jouzel, Jean-Marc Barnola, Jiancheng Kang, Volodya Y. Lipenkov

"The sequence of events during Termination III suggests that the CO2 increase lagged Antarctic deglacial warming by 800 ± 200 years and preceded the Northern Hemisphere deglaciation."
