Thanks Paul I've already been soapboxing on this one.

My disappointment is that learned folk with supposedly solid logic processing, still view events as "an all or nothing proposition". I see nothing yet that refutes an impact over Northeastern North America in the time frame. We know there have been wildfires ever since trees first sprouted and they continue right up to the present. On one hand, if I read the article correctly, widespread wildfires were the likely cause of the Younger Dryas Event. On the other hand widespread wildfires from one or more thermo-nuclear-like flashes from an impacting comet can't be a component of those wildfires. Seems like the logic breaks down. The reported occurrence of nanodiamonds and buckyballs from various sites was not addressed and may not have even been evaluated.

Reminds me of how you stack evidence selected in climate predictions: where the selection of data was not based on statistically-sound procedures .( e.g. excluding cases with suspected corrupt or incomplete collection errors, but selecting cases solely for purposes of underpinning the foregone test results). So we don't analyze any site suspected of containing nanodiamonds or buckyballs cause that carbon would skew 14C ratios? It is arguable that fungal-ly induced carbon could skew dating results yielding younger radiometric dates. We aren't privy to the experimental controls for accounting for those variables.

So their bottom line is that only "non-impact-ignited wildfires" could be involved in forcing northern hemisphere temperatures down for 800 years during an overall warming trend which was already melting continental ice sheets?

The

"The results of our study clearly falsify the

the extraterrestrial impact hypothesis. Both the finding
> that
the northern Folsom sites are earlier than the southern
Folsom
> sites, and the finding that there is a hiatus between
Clovis and Folsom in
> the south of the latter?s range as
well as spatial and temporal overlap of
> Clovis and Folsom
in the north run counter to the predictions of the

impact hypothesis."
