But how can we know when the candle was lit? The scientists worked independently of one another. We could try to match a pattern of rings on the furniture, with a pattern of rings in living oaks from a forest near to where it was made. Researchers can compare and match these patterns ring-for-ring with patterns from trees which have grown at the same time in the same geographical zone and therefore under similar climatic conditions. Second, radiocarbon dates on objects of known age have confirmed the reliability of radiocarbon dating, and hence dendrochronology, when applied to the last 2, years, at least. A fully anchored and cross-matched chronology for oak and pine in central Europe extends back 12, years, [20] and an oak chronology goes back 7, years in Ireland and 6, years in England. No fewer than twenty-three scientists responded to these claims, and the subsequent debate is nicely summarized by Scott Johnson at Ars Technica. It can be anchored by cross-matching a section against another chronology tree-ring history whose dates are known. Take, for instance, a piece of charcoal from an ancient campsite. Growth rings result from new growth in the vascular cambium , a layer of cells near the bark that botanists classify as a lateral meristem ; this growth in diameter is known as secondary growth.

    The evolving atmosphere filled rapidly with carbon, but this rate slowed as carbon found its way into the oceans and the biosphere. Measurement Limits Until the last few years, laboratories measured carbon content indirectly by extracting all the carbon from a sample and then counting its radioactive emissions.

    He noticed variations in the width of annual growth rings in yellow pine trees growing around Flagstaff, Arizona. Without stretching the analogy too far, let us imagine that the wax represents carbon

    However, most sources useful for the reconstruction of past climates have their shortcomings, and these inevitably stimulate controversy.
