PALEOCLIMATOLOGY/OCEANOGRAPHY: PREINDUSTRIAL LEVELS OF CO2


Item #d93jan31

"Palaeo-CO2 and Climate," R.A. Berner (Dept. Geol., Yale Univ., New Haven CT 06511), Nature, 358(6382), 114, July 9, 1992. Discusses methods for deducing ancient CO2 levels other than by analysis of air bubbles trapped in ice cores.


Item #d93jan32

"Do Glaciers Tell a True Atmospheric CO2 Story?" Z. Jaworowski (Inst. Phys., Univ. Oslo, POB 1048, Blindern, N-0316 Oslo, Norway), T.V. Segalstad, N. Ono, Sci. Tot. Environ., 114, 227-284, Apr. 1992.

Argues that the widely accepted value of 290 ppm for preindustrial CO2, determined from analyses of air trapped in glacial ice bubbles, is incorrect because the estimate is subject to invalid assumptions, processes in ice sheets, artifacts in ice cores, and arbitrary rejection of high readings. This outcome has led to a widely accepted false dogma of anthropogenic warming, which could have enormous negative impacts on our common future. (See following entry.)


Item #d93jan33

"Carbon Dioxide Climate Curves from Ice Cores," H.E. Heyke (Brunnenwiesenweg 17, W-7061 Lichtenwald Hegen, Ger.), Erdol & Kohle Erdgas Petrochemie, 45(5), 208-214, May 1992.

In determining the preindustrial levels of atmospheric CO2 from air trapped in ice cores, many basic laws of chemistry seem to have been largely ignored, and experimental errors have made the results rather doubtful. Such determinations should be repeated under improved and more careful conditions.
