An example of the ingenious technical work and hard-fought debates underlying the main story is the use of radioactive carbon-14 to assign dates to the distant past.

As for still earlier periods, carbon-14 dating excited scientists (including some climate scientists) largely because it might shed light on human evolution — the timing of our development as a species, and how climate changes had affected that.(2) It was especially fascinating to discover that our particular species of humans arose something like 100,000 years ago, no doubt deeply influenced by the ice ages.(3) A few scientists noticed that the techniques might also be helpful for the study of climate itself.

From its origins in Chicago, carbon-14 dating spread rapidly to other centers, for example the grandly named Geochronometric Laboratory at Yale University.

One application was a timetable of climate changes for tens of thousands of years back.

Many of the traditional chronologies turned out to be far less accurate than scientists had believed — a bitter blow for some who had devoted decades of their lives to the work.

Any contamination of a sample by outside carbon (even from the researcher's fingerprints) had to be fanatically excluded, of course, but that was only the beginning.
