We stand by our original review. There is no support for a cosmic-origin catastrophe at ~12,850 cal years BP. There is also no support that at ~12,850 cal years BP human populations diminished, late Pleistocene megafauna were wiped out or reduced, and an unique global climate change occurred. The comments are largely built around the same claims we previously rebutted (and rebut here again) based on a broad range of scientific research published in long-standing and recognized journals on impact cratering and mineralogy/geochemistry, as well as late Quaternary geology, paleoclimatology, paleobiology and archaeology. Evidence and arguments purported to support the YDIH involve flawed methodologies, inappropriate assumptions, incomplete comparisons, overgeneralizations, misstatements of fact, misleading information, unsupported claims, irreproducible observations, misinterpretation of fundamental data, logical fallacies, and selected omission of contrary information. These issues are discussed within broader themes in the conduct of scientific research. The burden of proof is on the developers and supporters of the YDIH to critically test their own hypothesis and to fully respond to a large, diverse body of critiques, observations and contradictory evidence. To date, they have failed to do this.

反驳 Sweatman、Powell 和 West 的“拒绝 Holliday 等人所谓的对 Younger Dryas 影响假说的反驳”


我们坚持我们的原始评论。没有证据支持宇宙起源的灾难发生在 ~12,850 cal 年 BP。也没有证据证明在 ~12,850 cal 年时 BP 人类人口减少，更新世晚期的大型动物群被消灭或减少，并发生了独特的全球气候变化。这些评论主要基于我们之前反驳（并在此再次反驳）的相同主张，这些论点基于发表在长期和公认的期刊上的关于撞击坑和矿物学/地球化学以及晚期第四纪地质学、古气候学、古生物学和考古学的广泛科学研究。据称支持 YDIH 的证据和论点涉及有缺陷的方法、不适当的假设、不完整的比较、过度概括、事实的错误陈述、误导性信息、无根据的主张、不可重复的观察结果、对基本数据的误解、逻辑谬误以及选择性遗漏相反信息。这些问题在科学研究的更广泛的主题中进行了讨论。YDIH 的开发者和支持者有责任批判性地检验他们自己的假设，并全面回应大量不同的批评、观察和相互矛盾的证据。迄今为止，他们未能做到这一点。
