GGG Ping.
(I don't see much difference in this and earlier articles)(?)

Did Comets Cause Ancient American Extinctions?

No.

A most likely cause was an ancient and earth minded ancestor of Albert Gore.

[DBrow]

“”You have to ask what kind of blast might peter out by the time it gets to Mexico and not have much effect on South America,”

Well, for one thing, an explosion’s force falls off as the cube of the distance (not the square) so the difference between Michigan and Michoacan could be considerable.

Tunguska flattened square miles when it hit yet Petrograd was unscathed.

[buck jarret]

Perhaps the megafaunas turned gay and lesbian.

[Eye On The Left]

I've used this graph on occasion to show people that Al Gore's CO2-temperature correlation is really a REVERSED one. Because one can clearly see that temperature increases (blue line) actually PRECEEDED CO2 increases (red line) all throughout this 400,000 year time interval. In fact, by an of average 800 years! Yet Gore makes the dishonest claim that it was CO2 that warmed the earth to get us out these past 4 glaciations (roughly every 100,000, the result of periodic changes in Earth's orbit and spin axis). BP = before present.

In any case, perhaps this same graph can be of use in this current discussion?

[Eye On The Left]

On second thought, the graph really isn’t that useful, even when zoomed 200%. I had hoped the sharp post ice age temp decrease (at ~13,000 yrs) might show up on it.

[montag813]

An Obama Presidency would be a good time for another comet strike.

[JasonC]

No.

Next idiotic brainstorm, please.

[TXnMA]

He and his colleagues have also found widespread and abundant minuscule diamonds and magnetic particles in the layer of Earth that dates to this time.

I agree that we archaeologists are missing much vital information when we simply screen the dirt to isolate (artifacts or whatever) and then toss that soil back in the hole without examining it with every possible analytical tool.

Of course, there is that ever-present limitation of cost... :-(

[CurlyDave]

Possibly NASA could arrange for a comet to hit Al Gore.

The classic two birds with one stone.

[yefragetuwrabrumuy]

Whatever it was, I suspect that its effects were just as pronounced in South America, possibly wiping out either an ancient Egyptian quality civilization, or the last of the giant “terror birds”, very large, predatory birds that might have existed as late as 15,000 years ago. Or both, as they might have co-existed.

When Indians later occupied the area, they had no idea who built the great cities there.

[ProtectOurFreedom]

One widely accepted hypothesis suggests that melting ice sheets and glacial lakes 12,000 years ago dumped so much meltwater into the oceans that it disrupted ocean circulation. This in turn cooled much of the planet, especially in the Northern Hemisphere.

Sounds like an AGW kook theory to me. Global warming melted the glaciers which then caused global cooling. Somehow I have a hard time buying into the warming causes cooling theory.

[Verginius Rufus]

The Houston Comets? No, the WNBA hasn’t been around that long.
