説明
<jats:title>The whole story</jats:title> <jats:p> An accurate, precise record of the carbon-14 ( <jats:sup>14</jats:sup> C) content of the atmosphere is important for developing chronologies in climate change, archaeology, and many other disciplines. Cheng <jats:italic>et al.</jats:italic> provide a record that covers the full range of the <jats:sup>14</jats:sup> C dating method (∼54,000 years), using paired measurements of <jats:sup>14</jats:sup> C/ <jats:sup>12</jats:sup> C and thorium-230 ( <jats:sup>230</jats:sup> Th) ages from two stalagmites from Hulu Cave, China. The advantage of matching absolute <jats:sup>230</jats:sup> Th ages and <jats:sup>14</jats:sup> C/ <jats:sup>12</jats:sup> C allowed the authors to fashion a seamless record from a single source with low uncertainties, particularly in the older sections. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6420" page="1293" related-article-type="in-this-issue" vol="362" xlink:href="10.1126/science.aau0747">1293</jats:related-article> </jats:p>
