Science Channel TV Special

This link is not informative, it simply supports the existence of the program.

I found this which is informative but not represenative of the episode I saw. The gist of what I saw was that world wide spontaneous combustion is not supported by the existence of charcoal in sufficient quantity outside the radius of the Yucatan impact site, and the survival of several frog species argues against acid rain on a global scale.

Bottom line, dinos were already in decline and were finished off by multiple impacts and volcanic activity after the Yucatan impact.

Like I said it is a controversy, not a resolution
