  1. Wow, the Comet Research Team’s (CRT) opening statement here:

    “However, such criticisms must be based on facts. Instead, many of the assertions made in the discussion by Holliday and coauthors are inaccurate. In this article, we present rebuttals of the most significant of their inaccurate assertions but decline to address unfounded opinions.”

    …will certainly leave a mark.

    AKA the CRT essentially said:

    “We will address your bad science and leave your intemperate statements stand and impeaching you.”

  2. The CRT paper was written before either the South African or South American paper came out.

    My count YDIH continent count is Eurasia, North America, South America and Africa.


    This is inaccurate. Impact-related proxies have been found in sediment samples from 23 Bayesian-dated sites in nine countries on three continents, as re-ported by Kennett et al. (2015; table 1). The average age ranges from∼18,640 cal BP in the Last Glacial Maximum through the entire YDepisode to 7,837 cal BP into the early Holocene, an average span of∼11,000 y
