Hi,

Unsurprisingly, Sweatman, Powell, and West have replied to Holliday et 
al. (2023)?s refutation of the YDIH with Sweatman et al. (2024). In response,
Holliday and associates replied with Holliday et al. (2024) and an open access
supplementary material, YDIH Skeptics (2024).

The publications are:

Holliday, V.T., Daulton, T.L., Bartlein, P.J., Boslough, M.B., Breslawski, R.P., 
Fisher, A.E., Jorgeson, I.A., Scott, A.C., Koeberl, C., Marlon, J.R. and 
Severinghaus, J., 2023. Comprehensive refutation of the Younger Dryas 
Impact Hypothesis (YDIH). Earth-Science Reviews, 247, p.104502.

I wonder how much time and money has been spent researching, debating, writing,
and publishing on this topic.

Yours,
