Two papers, both of which dispute the occurrence of wildfires
associated with a hypothetical impact event at the start of the
Younger Dryas, have been recently published. They are:

1. Marlon, J. R., P. J. Bartlein, M. K. Walsh, S. P. Harrison, K. J.
Brown, M. E. Edwards, P. E. Higuera, M. J. Power, R. S.
Anderson, C. Briles, A. Brunelle, C. Carcaillet, M. Daniels,
F. S. Hu, M. Lavoie, C. Long, T. Minckley, P. J. H. Richard,
A. C. Scott, D. S. Shafer, W. Tinner, C. E. Umbanhowar, Jr.,
and C. Whitlock, 2009, Wildfire responses to abrupt climate
change in North America. Proceedings for the National
Academy of Science. Published online before print

and 2. van der Hammen, T. and B. van Geel, 2008, Charcoal
in soils of the Aller?d-Younger Dryas transition were the
result of natural fires and not necessarily the effect of an extra-
terrestrial impact. Netherlands Journal of Geosciences (Geologie
en Mijnbouw) vol. 87, no. 4, pp. 359-361.

A paper about the role of climatic change unrelated to
extraterrestrial impacts in wildfire synchrony is:

Kitzberger, T., P. M. Brown, E. K. Heyerdahl, T. W. Swetnam,
 and T. T. Veblen, 2007, Contingent Pacific?Atlantic Ocean
influence on multicentury wildfire synchrony over western
North America. Proceedings of the National Academy of
Sciences of the United States of America. vol. 104 , no. 2.
pp. 543-548.
