12,900 Years Ago: North American Comet Impact Theory Disproved
ScienceDaily ^ | Jan. 27, 2009 | Unknown

Posted on 01/27/2009 3:06:57 AM PST by decimon

New data disproves the recent theory that a large comet exploded over North America 12,900 years ago, causing a shock wave that travelled across North America at hundreds of kilometres per hour and triggering continent-wide wildfires.

Dr Sandy Harrison from the University of Bristol and colleagues tested the theory by examining charcoal and pollen records to assess how fire regimes in North America changed between 15 and 10,000 years ago, a time of large and rapid climate changes.

Their results provide no evidence for continental-scale fires, but support the fact that the increase in large-scale wildfires in all regions of the world during the past decade is related to an increase in global warming.

When they mention ‘global warming’, I quit reading.

So by studying fire patterns SINCE the supposed event, he has been able to prove that the event never occurred?

What am I missing here?

Maybe fire patterns increased because IT TOOK A WHILE FOR IT TO ALL GROW BACK?

I hate these guys who say something is set in stone, a better title would be something like “Evidence found against ancient comet theory”, but I guess if he goes to parties, he gets more babes if he says “I disproved something...”

When I read that a single ‘scientist’ from Bristol, I got suspicious. It seems like it would be a herculean task to compare the data from samples over the entire continent.

Like you, when I reached the “global warming” part, I realized I was not reading about a scientist but a religious zealot who claims he knows the date of the coming, man-caused apocalypse.

The next-to-last paragraph in the story seems to contradict the initial claims:

They found clear changes in biomass burning and fire frequency whenever climate changed abruptly, and most particularly when temperatures increased at the end of the Younger Dryas cold phase.

What am I missing here? There is evidence that the globe has been cooling for at least the last decade.

Everything. You must report to The Consensorate for your annual conscienceness raising.

Unless I missed it, they haven't 'disproved' the theory that a comet struck the U.S. at about 12,000 years ago, but only that it didn't (so they say) lead to continent sized wild fires.

Must say, these scientists cover *all* the bases.

These psychos find evidence of global warming when the go out in the morning to pick up the paper.

I don't believe this scientist. With good reason: it was this "break" around 12,000 years ago that wiped out the larger mammals in North America (woolly mammoth, saber-toothed tiger, and several species of large bears) and wiped out much of human existence in what is now the North American continent. And it all happened in a VERY short period of time.

This stuff makes me chuckle! There is NO WAY they can know what happened 12,900 years ago. -continent wide wildfires.. come on now... Unless you were THERE, there is NO WAY to positively know this! It’s SPECULATION not science.
