Researchers at Scripps find evidence that glaciers are tougher than we might think

Global warming has been the hotly debated harbinger of the apocalypse in recent years. Rising ocean levels may put cities or perhaps entire states under salty ocean water while violent storms fueled by an over-warmed atmosphere wrack dry land.

Doom and gloom aside, one naturally occurring effect of raising ocean temperatures is the shrinking of polar ice caps and glaciers. The frozen water returning to the ocean contributes to climbing sea levels and should they disappear into the brine, could probably put most of the eastern seaboard under a pleasant warm ocean surf.

Or maybe they won't. Recently published data from a study done at Scripps Institute of Oceanography at the University of California, San Diego indicates that there may have been glacial growth even during one of the strongest climate warmings in Earth's history, known as the Cretaceous Thermal Maximum.

"Until now it was generally accepted that there were no large glaciers on the poles prior to the development of the Antarctic ice sheet about 33 million years ago. This study demonstrates that even the super-warm climates of the Cretaceous Thermal Maximum were not warm enough to prevent ice growth," explains Richard Norris, professor of paleobiology at Scripps and co-author of the study, titled "Isotopic Evidence for Glaciation During the Cretaceous Supergreenhouse." The study is published in the most recent issue of Science.

The researchers used two independent methods to harvest the data on which they base their claim. Both studies used microfossils from the Cretaceous period and examined them for telltale signs of glacial melt. In one test, the researchers used ocean surface dwelling microfossils and subtracted the ocean surface temperature record from the stable isotope record found in the fossils.

The second method involved bottom-dwelling and near-surface microfossils known as foraminifera. Stable oxygen isotopes were measured in these tests and were found to support the theory of growing icecaps via changing ocean chemistry. Both tests support the conclusion, and fall in line with previous studies which show that sea level fell 25-40 meters at the same time as the ice sheets would have been growing during the Cretaceous.

The catalyst for glacial growth during such a hot period is still a mystery, but some suggestions found in the study are that unusually cool summers could have fostered growth in the mountains of the current Antarctic ice cap, or that increased moisture in the air from the greenhouse affect could have increased winter snowfall in high latitudes and elevations.

That's not what he was saying here. Don't remember the speech where G.W. said, "We have to go to Iraq and capture Sadaam so that his people can try him." "We have to eliminate Sadaam by all means necessary" was the mantra.

Oh you are right, that's just the terrorist count. Other independent groups estimate anywhere from 300,000 civilians to 1 million... Thought I would error on the conservative side.

Easier = better? Really... Maybe we should just nuke all of the Middle East. Be easier to get the oil once the smoke clears..

That's right being liberal allows you to be selective in your criticism to make your point.

Oops. The highest (by far) estimate was the Lancet study which claimed 650,000...a study that not only has been proven inaccurate, but was later revealed to have been funded by Bush opponent George Soros, the billionaire bankroller of Kerry's presidential bid.

Yes, eliminate him from office. If you recall - we did tell him to turn himself in. So if he did die in a bombing or raid, it would have been his own fault anyway.

George Soros is an Independent Group? Thats a laugh. You mean the guy who funds media matters and moveon.org?

I wouldn't say all...we can keep Israel. But in all seriously, it would be much easier to just roll over one night and crush Canada to take Oil if we really wanted to take someones oil.

I wasn't aware that part of the catholic cirriculum. But being as I have no gone to church (outside of a wedding / funeral) in about 14 years, I would have to say NO.

Who said you're afraid? You just want to make everyone be like you so that you are no longer socially unacceptable. I personally do not cater to anyone but myself. Sorry to dissapoint.

Eh? They've found mass graves in Iraq with more than that in it. Estimates for the total number killed under Hossein run up to several million...and that's just his own people, not counting all the dead from Iraq's incursions into Iran and Kuwait. He killed some 300,000 Shias during the 1991 uprising alone.

> "At least turtles don't kill each other just to prove who has a bigger c*ck."

You couldn't be further from the truth. Dominance battles are common among animals of most species...and quite often, the loser of such contests is driven off, maimed, or even killed.

Next, I suppose you'll say that "animals never kill for pleasure"?

Animals do fight for dominance. But its part of their survival. For mating, for being leader of the pack... Etc. Survival of the fitest...

Men literally do fight and kill each other over stupid ass reasons, like who has more girth.

Animals cannot rationalize another solution. Humans can but choose not to.

Which animals?

Dominance displays aren't required for their survival. They're a behavior which has evolved as a competitive advantage....the same reason it exists in humans.

> "Which animals?"

Ah, an urban dweller, eh? Most carnivores will kill for sport. That includes all the big cats (including many housecats), some wolves and dogs, many marine species including killer whales, etc.
