On the recordJuly 28, 2003
What Tom Mullins said is totally consistent with what I talked about earlier. In the National Black Chamber of Commerce and the U.S. Hispanic Chamber of Commerce they talked about the unemployment rate and how it hurts poor people. I think that to be very true. Now I want to turn to temperature trends in the 20th Century. GCMs predict that rising atmospheric CO2 concentrations will cause temperatures in the troposphere, the layer from 5,000 to 30,000 feet, to rise faster than surface temperatures--a critical fact supporting the alarmist hypothesis. But in fact, there is no meaningful warming trend in the troposphere, and weather satellites, widely considered the most accurate measure of global temperatures, have confirmed this. To illustrate this point, just think about a greenhouse. The glass panes let sunlight in but prevent it from escaping. The greenhouse then warms from the top down. As is clear from the science, this simply is not happening in the atmosphere. Satellite measurements are validated independently by measurements from NOAA balloon radiosonde instruments, with records extending back over 40 years. This is very critical. The extremists will tell you warming is occurring. If you look at this chart of balloon data, extremists will tell you that warming is occurring, but if you look more closely you see that temperature in 1955 was higher than temperature in 2000.
