Ancient global warming was jarring, not subtle, study finds
Los Angeles Times ^ | January 5, 2007 | Robert Lee Hotz

Foreshadowing potential climate chaos to come, early global warming caused unexpectedly severe and erratic temperature swings as rising levels of greenhouse gases helped transform Earth, a team led by researchers at UC Davis said Thursday.

The global transition from ice age to greenhouse 300 million years ago was marked by repeated dips and rises in the amount of carbon dioxide in the atmosphere and wild swings in temperature, with drastic effects on forests and vegetation, the researchers reported in the journal Science.

"It was a real yo-yo," said UC Davis geochemist Isabel Montanez, who led researchers from five universities and the Smithsonian Museum of Natural History in a project funded by the National Science Foundation. "Should we expect similar but faster climate behavior in the future? One has to question whether that is where we are headed."

The provocative insight into planetary climate change counters the traditional view that global warming could be gradual and its regional effects easily anticipated.

Over several million years, carbon dioxide in the ancient atmosphere increased from about 280 parts per million to 2,000 ppm, the same increase that experts expect by the end of this century as remaining reserves of fossil fuels are burned.

No one knows the reason for so much variation in carbon dioxide levels 300 million years ago, but as modern industrial activity continues to pump greenhouse gases into the air at rapid rates, the unpredictable climate changes that took millions of years to unfold naturally could be compressed into a few centuries or less today, several experts said.

Carbon dioxide levels last year reached 380 ppm, rising at almost twice the rate of a decade ago, experts said. Average global temperatures have been rising about 0.36 of a degree Fahrenheit per decade for the last 30 years.

Still, the transformation

Dino Gas, just like Gore talks about cow flatulence.

Does anyone realize how large an SUV would have been required to carry 6 full-grown brontosaurs? I have estimated the size of the engine at 3000 cubic inches with 5000 horsepower - and that does not even count the turbos. Typical milage was .10 per gallon and they did not even have catalytic converters.
Butt since they wouldn't even have windows that you could roll up (for good reason), there would be some weight savings––maybe enough to get mileage to .101 mpg.

Sigh ... wishes for a time machine to see what feeding broccoli, cauliflower, black beans and garlic would do to a brontosaur....

Not even close. Since one apatosaur weiged 40 tons, you looking at multiplying the figures on a normal suv by approximately 500. If the Chevy Tahoe V8 has 325 horsepower has 325hp, then the prehistoric ride would need about 162,000hp. Of course, they wouldn't call it horsepower, as horses hadn't evolved yet.

"... Over several million years, carbon dioxide in the ancient atmosphere increased from about 280 parts per million to 2,000 ppm, the same increase that experts expect by the end of this century as remaining reserves of fossil fuels are burned.... "

BS ALERT!!

I consider myself well-read about climate change and nowhere have I come across anyone anywhere who has stated that the amount of carbon dioxide in the atmosphere will approach 2000 ppm. (This doesn't mean that someone hasn't stated it - just that I have not seen it in Scientific American, Science, Nature, or other journals like that.) I just did a quick google and found that even the radical environmentalists are stating that the figure for the end of the century will be 450 to 550 ppm.

The other BS alert: "...as the remaining reserves of fossil fuels are burned..." Talk about hyperbole! All the natural gas, all the oil, all the methane hydrates are gone by the year 2100?

So, in essence, we're all going to die. Which is true for all of us. I won't make it to 2100. I don't think my death will be from global warming, though.

In the meantime, as I turn to me left, I can see the temperature outside my window. It is now -40.9 degrees, about 35 degrees below average for this place and this time of year. Must have something to do with global warming.

Its terrible - we haven't seen these kinds of temperature increases since 125,000 years ago (and 225,000 and 325,000 and 425,000 years ago).

Luckily I have a $1 million dollar grant that is funding my research into determining if temperture variations are cyclical. Early models are inconclusive and it will no doubt require more time and money.

Don't dismiss this article, folks, because this is the key to smacking these idiot global-warming certaintists right across their arrogant temples.

Ask them "Why and how did 'Global-like-Warming-man®' happen before man was even around...dude?...Take your time."

Then give them an example that strikes home to these essentially selfish and hypocritical pinheads:

"OK, like dude, man...suppose the city said that there was a smell coming from your neighborhood, 'nd like dude...they kinda figgered it was cuz of your septic tank...'nd cuz-a-that, they're like demanding that you spend what your house is worth to like dig it up and then follow all the potential drain points to like sanitize it...man. But...don't question their judgement on that, man, cuz that would be like totally reactionary...just accept it and dig deep, dude."

We all know what these self-centered and hypocritical schmucks would say.

From all the research I have read I come to a couple of conclusions:

1) Global warming cycles are tied to hundreds of year long solar cycles of the sun.

2) Mankind and all animal life in general benefit as a whole from warmer temps. More food supply.

3) Their is nothing we can do about this. We should be responsible and focus on pollution going into our atmosphere because thier is conclusive proof we have damaged the ozone causing lots more cancer and lung-ilness.

mass extinction.
fever spikes
instability, erratic

A quick list of the fear words in this article. Is this a news article or an editorial?

The most important line in the article is the very last one:

"It suggests," she said, "that the normal behavior in major climate transitions is instability, erratic temperature behavior and carbon dioxide changes."

Get that? Changes are NORMAL!

solar cycles of the sun

Isn't that a little bit like "dampness of water?"

This baby could haul them. It has 3,400 horsepower & gets 0.3 mpg. Allowing for a longer unit for comfortable seating, and more power for higher speeds (the Cat can go 40 mph), your estimates are probably pretty close.

Here we are now changing the rules in midstream; it will no longer be enough to counter the human influence by pointing to warming periods in the past because it is the speed with which the warming takes place that is at the hand of man, therefore, only man can change it back or stop it.

Perfect ploy, it's still my fault and I didn't do a thing.

And, pig will fly, too. Better get all your Liberal friends to invest in pork belly futures, NOW! Tell 'em to mortgage the house, invest their whelps college funds - get in while there is still time!

These are the same lunatics who get tears in their eyes talking about how the plains were black with buffalo before whitey came along and killed them all for their hides.

Ya know, I like yer thinkin'. I'm in a private mail discussion with a tinfoil hat wearer (who I believe won't go public with his comments because he knows he'll get his head handed to him by FReepers 100 times smarter than he is) who quotes me stuff from James Hansen (apparently his hero) and some report that "proves" that the sun has less influence on GW than previously believed. In his mind, that means that Al Gore and Ed Begley are the enviro-gurus. These people scare me that they cannot think rationally or intelligently.

But, I guess that SOMEBODY has to vote for Democrats!!

Listen: Fully 1/3 of Americans believe that George Bush had something to do with 9/11. I posted a thread on it in September. As a matter of fact moveon.org organized a large protest about said "conspiracy" at the WTC even as family members were reading the names of the dead. I work across the street and the only reason I didn't knock one of them out was out of respect for the ceremony. There out there. I'm well aware of it.

Liberalism is a mental disorder.
