CAMBRIDGE, MA–TERC Senior Engineer Paul Wagoner is the lead author of "Climate Change in a Shoebox: Right Result, Wrong Physics" —an article appearing in the May 2010 issue of the American Journal of Physics. Paul and co-authors Chunhua Liu and Roger Tobin of Tufts University report on their investigation of a common classroom demonstration that purports to show the role of carbon dioxide in increasing greenhouse warming. The authors compared the results of the demonstration with carbon dioxide to the results obtained using argon gas, and show with experimental data and a theoretical analysis that the warming found in the demonstration is due not to the infrared absorption of carbon dioxide but rather to its greater density compared to air.

The results apply only to the analysis of classroom-scale demonstrations, and do not call into question current scientific models of global greenhouse warming.
