On the side of people disputing the Younger Dryas Impact hypothesis there is:
Kerr, R. A., 2010, Mammoth-Killer Impact Rejected. Science Now, August 30, 2010 http://news.sciencemag.org/sciencenow/2010/08/mammoth-killer-impact-rejected.html Dalton, R., 2010, Comet theory carbonized: Sediment studies rule out impact as cause of ancient cold spell. Nature News. August 31, 2010. http://www.nature.com/news/2010/100831/full/news.2010.441.html Impact hypothesis loses its sparkle, Physorg. August 30, 2010, http://www.physorg.com/news202382634.html http://www.physorg.com/news195979458.html Kerr, R. A, 2010, Mammoth-Killer Impact Flunks Out. Science, vol. 329, no. 5996, pp. 1140 - 1141 DOI: 10.1126/science.329.5996.1140 http://www.sciencemag.org/cgi/content/summary/329/5996/1140 The paper is: Daulton, T. L., N. Pinter, and A. C. Scott, 2010, No evidence of nanodiamonds in Younger–Dryas sediments to support an impact event. Proceedings of the National Academy of Science of the United States. Published online before print August 30, 2010, doi: 10.1073/pnas.1003904107 http://www.pnas.org/content/early/2010/08/26/1003904107.abstract?sid=f62eef7c-9d13-48e9-a003-ddd93d93d75b On the other hand, the BBC Article stated: “Allen West said further nanodiamond evidence in support of the impact theory would be published in the coming weeks.” One of these papers is: Kurbatov, A. V., P. A. Mayewski, J. P. Steffensen, A. West, D. J. Kennett, J. P. Kennett, T. E. Bunch, M. Handley, D. S. Introne, S. S. Que Hee, C. Mercer, M. Sellers, F. Shen, S. B. Sneed, J. C. Weaver, J. H.
