Do Urban CO2 Domes Contribute to Urban Heat Islands?
Reference Balling Jr., R.C., Cerveny, R.S. and Idso, C.D. 2002. Does the urban CO2 dome of Phoenix, Arizona contribute to its heat island? Geophysical Research Letters 28: 4599-4601. Background Past research in Phoenix, Arizona has demonstrated the existence of a well-developed urban heat island and a well-developed urban CO2 dome that are spatially and temporally coherent. Given the great interest in the climate-alarmist claim that the historical increase in the air’s CO2 content is responsible for the global warming of the past century or so, the authors thought it would be advisable to see if the Phoenix CO2 dome is significantly contributing to the Phoenix heat island. What was done Over a 14-day period in January 2000, the authors obtained vertical profiles of atmospheric CO2 concentration, temperature and humidity over Phoenix, Arizona from measurements made in association with once-daily aircraft flights that extended through, and far above, the top of the city’s urban CO2 dome
