Volcanic Warming Eyed in 'Great Dying'

My theory on the Great Dying is that some species had reached a state of advancement in intelligence and technology that they were able to see into the distant future.

Upon seeing the event of Hillary Rodham, that decided that the only prudent course to save the universe was mass extinction.

Sadly, they failed.

Once you expose a huge amount of underwater sediment to the atmosphere, two very bad things happen — a huge amount of carbon in the sediments is released and also methane. Once (methane) hits the atmosphere it's the most efficient greenhouse gas on the planet," he said.

So the current "Global Warming Trend" advertised by the left will actually cause sea levels to rise thereby reducing the amount of underwater sediment to the atmosphere, reducing greenhouse gasses?

These things are pretty complicated.

Really, Really enormous volcanic eruptions (Like the "Siberian Traps" eruption that covered an area the size of Europe with Lava and made every eruption of Yellowstone look like a joke by comparison) both cool the earth and heat it up.

They initially cool the earth with SO2 emissions; so it gets real cold, really fast. Then longer term you get global warming because of greenhouse gas emissions that stay in the atmosphere much longer.

tHEY WERE KILLED BY A GIANT fART?.....

"90 percent of all marine life and nearly three-quarters of land-based plants and animals went extinct."

You mean Darwin's progressive evolution didn't occur?

Cataclysm is the key to species' existence and extinction?

Is the "Theory of Evolution" as posed by Darwin and contradicted by these scientific facts expunged from our schools?

I'd guess that the tususami released more methane than a billion SUVs in a hundred years.

"the absence of evidence isn't evidence for absence."

The same thing can be said for WMDs.

[Strategerist]

Pretty clear you don't have even have the foggiest understanding of evolution.

Where do you get this from?

[LibWhacker]

But catastrophic events don't contradict evolutionary theory.

What's the lowest percentage of oxygen a human can live in and what percentage of oxygen is the equivalent to, say, the amount of oxygen at the top of Everest (which is about as high as humans can survive)? Anyone know?

Agreed. I've seen some discovery channel shows detailing this eruption. It really makes us appreciate how "calm" things are now geologically. After the tsunami, it seemed like most thought it was the biggest geological event ever.

I am curious if you saw anything new in this article. I saw a discovery channel program last year that mentioned the Russian volcano eruption as the probably cause of the great extinction. I was under the impression that this has been the prevailing hypothesis for a while.

Ok, according to Intelligent Design, God did it so there is no need for this absurd research. Wasting taxpayers dollars on professor's salalries when we all know it was God's will and we shouldn't think to much about it < /sarcasm>

More likely: a Global Winter. The lowering of sea levels he talks about is related to Ice Ages, where water on Earth and in its atmosphere is locked up in ice and glaciers, instead of flowing back into the sea again.

Sounds like a Dem request for a special prosecutor.

[Old Professer]

Sounds like my ice bucket.

Carl Sagan used the absence/evidence argument famously in the 1970s, I believe; his disincorporated remains watch over us as we speak.

[Old Professer]

About 19%.
