Tiny Gems, Cosmic Impact

Sorry, this cannot be true. Catastrophic climate change cannot occur without human intervention. There is no force in the universe more powerful than humans!

I really hope davidvm is kidding because even if we can coax life from dirt like God did, we can't make our own dirt. ;-D Also, if humans are the most powerful force, how come we can be killed?

davidvm, have you never been in a earthquake, seen a storm or watched the force of an angry ocean hit the shore? Humans have nothing to do with a volcano and yet the dust cloud from an eruption can change the climate on earth for years. Surly you were being facetious with your post. This is a fascinating article and should their research prove out, it would explain so much that has been heretofore a mystery.

Heellllooooo! Sarcasm alert!

"davidvm" is throwing out some Global Warming Denier humor, y'all!

He's now on on Official Notice.

it happened then, and it's going to happen again sooner or later. liberals be damned on their reasoning. bush's ancestor's prolly killed off the clovis and company. change happens people

Look up something called the "vela-fragment". You may find it insightful. That layer of scorched earth is a reminder of the last age of man, and the precarious status of the current one. The Natural Force will always win, we are powerless against it. And only the adaptive and open-minded have any hope of continuation. We can only attain a symbiosis with our planet. Anything else will ensure our destruction as a species.

Sunlight could not come through. Imagine what it must have been like ! You know, Native Americans have many stories about a time of total darkness when the world was flooded by a sudden darkness that eliminated animal species. Could this be a memory of a true historical event ?

Davidvm ...while excluding the "universe" ...is right....we have been altering our environment since we started farming ...and fire, sadly we are near to destroying the most abundant and bottom of the food chain lifeform simply by acidifying our oceans. Where do you think that'll lead us? An impact could also explain why there aren't more clovis tools on the eastern coastal regions of the US ..

Just to be clear ...i was referring to the last part of his comment ...not the first part ;)

So -- diamonds aren't a girl's best friends, after all?!?!

Ya gotta shake your head in bemused wonder at those who don't understand the science (and sometimes art) of archeology and paleoecology... This work is just another piece in assembling the complicated jigsaw of earth's sometimes turbulent, and always changing, history. The truth WILL set us free - from the myths and superstitions that get erected in the absence of demonstrable evidence, whether the children of Bishop Usher like it or not.

Also in the news: Jupiter pulled in another big comet recently. The idea to put Jupiter out there is a good one, and so far has worked out well for us. Thank you God.
