Arguably, few research topics engage so many different fields of science and have such a profound impact on our understanding of Earth and Solar science as the history of C in the Earth's atmosphere and the surface and deep oceans.

Over the past decade we have witnessed a remarkable development and proliferation of accelerator mass spectrometers; these instruments have reduced the counting time by a factor of 100 and reduced the sample size by a factor of 1000 compared to the classic B-counting systems.

It is estimated that nearly 90% of all measurements made at the more than 50 active accelerator mass spectrometry laboratories are radiocarbon dates.

This dramatic increase in the number of radiocarbon dates is driving the demand for a radiocarbon calibration program that spans the entire radiocarbon timescale from the present to 55,000 years BP.

Of practical importance to a wide range of scientific disciplines is the radiocarbon calibration, which is used for converting radiocarbon ages to calendar years; essential for measuring time and rates of change for numerous scientific fields.

    But well-intentioned people may be uncomfortable with intense emotions or believe that they are helping when they are actually invalidating. The truth is that validation is not self-acceptance, it is only an acknowledgement that an internal experience occurred.
