Wolbach et al. published two papers on the Younger Dryas Impact Hypothesis (YDIH)—the paleoenvironmental effects of a purported cosmic impact at the beginning of the Younger Dryas Chronozone (YDC). Part 1 includes a selective summary of previous discussions of the YDIH but leaves out key reviews, uncritically accepts previous interpretations of purported impact, and fails to take into account abundant criticisms and contradictory data. A discussion of icecore evidence focuses only on the beginning of the YDCrather thanona longer interval thatwouldallow the context of claimed impact indicators to be evaluated. The exceptionalism claimed for many of the key data points is the result of exaggerations, and the graphical analyses themselves are not reproducible. Part 2 presents data from sedimentary records. The authors assume that impacts triggered widespread fires, but the evidence for such a link between extraterrestrial impacts and wildfires is weak. The presence of charcoal at the beginning of the YDC (YDB) fails to unambiguously support the hypothesis of impact-related fires because there is also a large peak at the end of the YDC. Stratigraphic markers used to argue for widespread burning, such as the Usselo soil of northwest Europe and the blackmat of the southwesternUnited States,were shownby their original investigators to have no plausible link to an impact event. Human population decline in North America is not supported by abundant published

约 12,800 年前的年轻仙女木宇宙撞击引发的非凡生物质燃烧事件和影响冬天，第 1 部分和第 2 部分：讨论

沃尔巴赫等人。发表了两篇关于 Younger Dryas Impact Hypothesis (YDIH) 的论文——在 Younger Dryas Chronozone (YDC) 开始时所谓的宇宙撞击对古环境的影响。第 1 部分包括对 YDIH 先前讨论的选择性摘要，但省略了关键评论，不加批判地接受了先前对所谓影响的解释，并且没有考虑大量批评和相互矛盾的数据。对冰核证据的讨论仅集中在 YDCrather thanona 更长间隔的开始，这将允许评估声称的影响指标的背景。许多关键数据点的例外论是夸大其词的结果，图形分析本身是不可重复的。第 2 部分介绍了沉积记录中的数据。作者假设撞击引发了广泛的火灾，但外星撞击与野火之间存在这种联系的证据很弱。YDC (YDB) 开始时木炭的存在不能明确支持与撞击相关的火灾的假设，因为 YDC 结束时也有一个大的峰值。用于论证广泛燃烧的地层标记，例如欧洲西北部的 Usselo 土壤和美国西南部的黑土，最初的研究人员表明，它们与撞击事件没有合理的联系。大量发表的论文不支持北美人口下降 YDC (YDB) 开始时木炭的存在不能明确支持与撞击相关的火灾的假设，因为 YDC 结束时也有一个大的峰值。用于论证广泛燃烧的地层标记，例如欧洲西北部的 Usselo 土壤和美国西南部的黑土，最初的研究人员表明，它们与撞击事件没有合理的联系。大量发表的论文不支持北美人口下降 YDC (YDB) 开始时木炭的存在不能明确支持与撞击相关的火灾的假设，因为 YDC 结束时也有一个大的峰值。用于论证广泛燃烧的地层标记，例如欧洲西北部的 Usselo 土壤和美国西南部的黑土，最初的研究人员表明，它们与撞击事件没有合理的联系。大量发表的论文不支持北美人口下降
