A statement by Professor Szymon Suckewer in PAW’s March 17 article about Princeton’s climate skeptics deserves clarification. Suckewer says that his own research has convinced him that “increased CO2 levels caused by human activity have little to do with rising global temperatures, and that most of the temperature increase is caused by changing of the water-vapor concentration in the atmosphere, possibly due to changing of the ocean currents.” These changing currents and the effect of vapor on climate are complicated and not well understood, explained Suckewer, a professor of mechanical and aerospace engineering, and “to properly include their contribution to global temperature change in computer climate modeling requires much more study.”
The Princeton men’s lacrosse team beat Brown 9–7 April 3. The score was incorrect in the April 28 edition of PAW.
