How things have changed. My first exposure to the science of climatology was in 1980, when I took an upper-division Physical Climatology course at the University of Utah. I still have the textbook: Smith, 1975, Principles of Applied Climatology.
The picture is a scan showing just about everything the book said about CO2 and climate change.
A few thoughts:
1. Climatologists in the 1970s predicted that atmospheric CO2 would increase to 418–450 ppm by 2010 [the atmosphere just hit 400 ppm this past few months], and a doubling of atmospheric CO2 by sometime in the 21st century.
2. Climatologists in the 1970s predicted global warming of 2° to 3°C in the 21st century because of this increase of atmospheric CO2.
3. There was no discussion in the textbook about the implications of a global 2° to 3°C temperature increase.
4. I didn’t make any marks or notes in the section, so it didn’t make too much of an impression on me at the time.
Grace and Peace
