Solar Variability and Climatic Change:

Isotope, Tree Ring and Other Proxies





"I arrived at the University of Arizona in time for the fall semester of 1957. The Geology Department had been criticized by the Physics and Chemistry Departments as a good pick and hammer department but behind the times. Urey, a chemist, had initiated the use of stable isotopes in geology, making use of Neir's advances in mass spectrometry. Neir, a physicist, had advanced geochronology; Blackett, a physicist, had initiated the field of geomagnetism; and Libby, a chemist, had developed 14C dating. I was supposed to bring the department into the post-World War II modern age of science with the commission to build an up-to-date 14C laboratory and to build a K Ar laboratory.
