Two hints.

1) This would be a very poor thread to choose to engage in flamewarring or flamebaiting.

2) It would be wrong to try to guess my position based on me posting this thread.

Correct!

LOL

I like your style!

So in the past, these organisms sucked carbon dioxide out of the air. But now that we are burning fossil fuels, these organisms will become estinct. Why? Because of the carbon dioxide?

Does not compute. Global warming sky is falling stupid computer model bump.

"However, in a related study published in Nature on Sept. 25, 2003, Caldeira and LLNL physicist Michael Wickett found that unrestrained release of fossil-fuel carbon dioxide to the atmosphere could threaten extinction for these climate-stabilizing marine organisms."

They just HAVE to add the propanda about "excess atmospheric CO2". Exactly "why" should a few more ppm of CO2 "threaten extinction" for critters who make their shells out of calcium carbonate?? Seems to me that it would be more likely to make them flourish in greater abundance.

"The most recent ice ages were mild enough to allow and possibly even promote the evolution of modern humans," Caldeira said. "Without these tiny marine organisms, the ice sheets may have grown to cover the earth, like in the snowball glaciations of the ancient past, and our ancestors might not have survived."

"The most recent ice ages were mild enough to allow and possibly even promote the evolution of modern gogatons," Xizirina said. "Without these hairless primates, the ice sheets may have grown to cover the earth, like in the snowball glaciations of the ancient past, and our ancestors might not have survived."

So there were glaciers at the equator. The whole earth must have been covered with ice. I guess it all piled up at the high points and left the ocean basins empty, right? Sure. If not, where did all the water go?

And I also believe that they know enough to model the atmosphere and predict whether or not CO2 will concentrate in the air or be absorbed in the water. Their many successes to date in such predictions (can anyone name one?) should give us plenty of confidence in their methods.

And what does this have to do with evolution?

[vpintheak]

Whatever! People will never stop at trying to explain the unexplainable. Unless you believe in God that is, then it is easy to explain.

This whole article is pure total .....

But in Precambrian times (which lasted up until 544 million years ago), marine organisms in the open ocean did not produce carbonate skeletons -- and ancient rocks from the end of the Precambrian geological age indicate that huge glaciers deposited layers of crushed rock debris thousands of meters thick near the equator. If the land was frozen near the equator, then most of the surface of the planet was likely covered in ice, making Earth look like a giant snowball, the researchers said.

A nice Scientific American article on the Snowball Earth hypothesis, which has gained considerable acceptance. (But some people think it was really only a "Slushball Earth.")

Actually it is quite easy to tell you are an evolutionist from the posting of this thread. Evolutionists cannot find any evidence for their position so they keep posting just so stories like this one that has no facts, no evidence, but says that evolution has been proven again.

Scientific predictions are made either about things which may occur in the future or things that have never been observed. This is neither, this is a story about something which has been observed and is already known. It is not a prediction, it is not science, it is an attempt to cover up the fact that the Cambrian explosion completely destroys the theory of evolution as the evolutionists Gould and Eldredge claimed.

One day, God and a scientest were debating crevo on Free Republic. They were making no headway in their heated exchange, so God decided a practical demonstration was necessary. God says, can science do this? And scooping up a handful of earth He created a man. The scientest said no problem and reached down for some dirt. Hey, no fair, exclaims God. Make your own dirt.

The article is pretty sketchy, and leaves a lot of questions unanswered which I presume are addressed in the actual paper. Since it hasn't been published yet it's not currently available, but the following website has several prior papers by Ridgwell available for viewing, and since CO₂ seems to be the running theme, they may shed some light on the same issues: http://lgmacweb.env.uea.ac.uk/e114/publications.html.

and LLNL physicist Michael Wickett found that unrestrained release of fossil-fuel carbon dioxide to the atmosphere could threaten extinction for these climate-stabilizing marine organisms.

LOL, course they would have to explain how these climate-stabilizing marine organisms functioned quite well in CO2 concentrations upto mid-Cambrian 7000ppm levels (over 16 times current levels) with no probs.

 

Global Surface Temperature and Atmospheric CO2 over Geologic Time 

Late Carboniferous to Early Permian time (315 mya -- 270 mya) is the only time period in the last 600 million years when both atmospheric CO2 and temperatures were as low as they are today (Quaternary Period ).

Temperature after C.R. Scotese
CO2 after R.A. Berner, 1994

•     There has historically been much more CO2 in our atmosphere than exists today. For example, during the Jurassic Period (200 mya), average CO2 concentrations were about 900 ppm or about 2.5 times higher than today. The highest concentrations of CO2 during all of the Paleozoic Era occurred during the Ordovician Period, exceeding 6000 ppm -- more than 16 times higher than today.

•     The Carboniferous Period and the Ordovician Period were the only geological periods during the Paleozoic Era when global temperatures were as low as they are today.
  
  To the consternation of global warming proponents, the Late Ordovician Period was also an Ice Age, with CO2 concentrations nearly 15 times higher than today-- 5500 ppm. According to greenhouse theory, Earth should have been exceedingly hot. Instead, global temperatures were no warmer than today. Clearly, other factors besides atmospheric carbon influence earth temperatures and global warming.
