Ninety-five percent of the activity of Oxalic Acid from the year 1950 is equal to the measured activity of the absolute radiocarbon standard which is 1890 wood. This is the International Radiocarbon Dating Standard.The prodigious mobilization of science that produced nuclear weapons was so far-reaching that it revolutionized even the study of ancient climates.Nuclear laboratories, awash with funds and prestige, spun off the discovery of an amazing new technique — radiocarbon dating.

So given that the half-life of carbon-14 is 5730 years, consider a sample of fossilized wood that, when alive would have contained 24 g of carbon-14. It also has some applications in geology; its importance in dating organic materials cannot be underestimated enough.In 1979, Desmond Clark said of the method “we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation” (3).Climate science required the invention and mastery of many difficult techniques.These had pitfalls, which could lead to controversy.
