Bristlecone pine carbon dating
This record has been used, among other things, to calibrate the radiocarbon timescale (the rate of radiocarbon production in the atmosphere is not constant over time, thus the need for calibration). Climatic variations and forcing mechanisms of the last 2000 years. Multi-millenial dendroclimatic studies from the western United States. This has permitted building a continuous chronology from the present back to 6828 BC (Hughes and Graumlich 1996).
Creationists have shown that the biblical kind is usually larger than the ‘species’ and in many cases even larger than the ’genus’—see my article Ligers and wholphins?
The Bristlecone pine became famous in scientific circles through the work of Dr.
Edmund Schulman (1908-1958) of the University of Arizona.
The radiocarbon method was developed by a team of scientists led by the late Professor Willard F.
Libby of the University of Chicago in immediate post-WW2 years.
