What were we talking about again?
Gorebull warnings L0L
I tried talking global warming and anthropomorphism and you all yawned. Then we got into the vanities and I...I...I can’t help myself.
I’m not SILLY. I mean I try to be silly but never try to emulate SILLY. Does SILLY talk about anthropomorphism in fictional literature and how it’s very definition parallels the fiction of man-made climate change? NO!!! Why? Because that wouldn’t be silly, nor would it be SILLY, which I am not. The person.
Honestly. I dont understand the aversion to vanitys.
Of course we relegated this to chat by yukking up on a vanity, but people yuk it up on AP storys all the time and those dont get relegated to chat.
This TAX the world because the sun shines stuff is totally out of control and the original poster makes a valid point.
Why is it a valid argument if the MSM brings it up but not if it is put forth by joe blogger?
These Global warning twits will be taxing the CO2 in sodas soon
"Vanity...Definately my favorite sin."
I don't either. I mean, they're great for keeping all my girl-products like lotions, hairbrushes and cosmetics and stuff.
And I like to sit at one and put on my "face" before going out.
They're really quite convenient.
A well written vanity IMHO Lilpug, beats anything Katey Couric ever wrote.
These Global warning twits will be taxing the CO2 in sodas soon
Well, at least it was an educated hijacking.
Convenient and well made
My contribution wasn't exactly educated.
It was mostly silly.
Not SILLY, the FReeper, just silly.
Everything that has lived or died on this planet produces Co2
Al Gore and his Ilk are nuts
Still, a fun diversion!
I gotta crawl into bed. It isnt 11 am for me.
That would cause Sonic drive-in restaurants to start offering truffles and fois gras.
We'd be treading into some uncharted waters there....
WTF? There is a quandry
Me neither. I'm still in Houston 'til Wednesday morning, 'member? :)
I must be off to study the insides of my eyelids as well.
"This thread has gotten extremely silly."
My hovercraft is full of eels.
If I said you had a great body would you hold it against me. I am no longer infected.
Good night all.
Now, I see why there are so many weird posts in mid-morning when I'm back at my other "home" 'round the globe.
It's all coming clear to me now...
Really, is this the new name? I did not get the memo.
Need to bookmark this link. Remind me if I slip again.
Antarctic Ice Core Hints Abrupt Warming Some 12,500 Years Ago May Have Been Global (http://www.sciencedaily.com/releases/1998/10/981002082033.htm)
ScienceDaily (Oct. 2, 1998) An analysis of an ancient Antarctic ice core indicates an abrupt climate warming occurred there about 12,500 years ago, an event previously thought to have primarily influenced climate in the Northern Hemisphere.
Geologic temperature record
James White, a paleo-climatologist at the University of Colorado at Boulder, said changes in stable isotope ratios — an indicator of past temperatures in the Taylor Dome ice core from Antarctica — are almost identical to changes seen in cores from Greenland’s GISP 2 core from the same period.
“The ice cores from opposite ends of the earth can be accurately cross-dated using the large, rapid climate changes in the methane concentrations from the atmosphere that accompanied the warming,” White said.
The evidence from the greenhouse gas bubbles indicates temperatures from the end of the Younger Dryas Period to the beginning of the Holocene some 12,500 years ago rose about 20 degrees Fahrenheit in a 50-year period in Antarctica, much of it in several major leaps lasting less than a decade.
“We used to think this climate change signal from the Younger Dryas to the Holocene was a big event in the Arctic, but not much more than a blip on the screen in the Antarctic,” said White, also a CU associate professor of geology and former interim director of the National Ice Core Laboratory in Lakewood, Colo. “But these findings throw a monkey wrench into paleo-climate research and rearrange our thinking about climate change at that time.”
A paper principally authored by research associate Eric Steig and co-authored by White and Scott Lehman, all of CU’s Institute of Arctic and Alpine Research, was published in the Oct. 2 issue of Science. The paper also included co-authors from Washington State University, the University of Rhode Island, Princeton University, the University of Texas at Austin, the University of Washington and the U. S. Geological Survey.
Deep-sea sediment cores from temperate regions, combined with arctic ice core evidence, confirm the climate warmed rapidly at the end of the Younger Dryas in the Northern Hemisphere, said White. But the amount of methane — a greenhouse gas primarily produced in tropical regions — that was found recently in the Taylor Dome Antarctic ice core argues for a more global climate-warming episode 12,500 years ago.
“What the Taylor Dome ice core seems to be telling us is there was a synchronization of warming at the end of the Younger Dryas at both poles,” said White. “This strengthens the argument that the warming phenomenon was global since the cores from both poles seem to be dancing to the same tune at the same time.”
Other Antarctic ice cores from the same time period like the Byrd and Vostok cores drilled in Antarctica’s interior contain climate records that do not correlate well with the Taylor Dome ice core, which was drilled on the southern edge of the continent near the Ross Sea, said White.
“There is no Rosetta stone ice core,” said White. “It is becoming clear that ice cores in different parts of the major ice sheets record the different climates in those areas. The Taylor Dome ice core may correlate more with Greenland ice cores in part because it was taken near the Ross Sea, an area of active ocean-atmosphere heat exchange today.”
Chemical changes seen in ice cores are helping scientists understand how humans are “presently re-arranging Earth’s energy budget and the global carbon cycle by increasing greenhouse gases in the atmosphere,” he said. The research team used both changes in atmospheric methane and the differing isotopic ratios of molecular hydrogen found in ice cores at both poles to reach their conclusions.
Antarctic Seafloor Core Suggests Earth’s Orbital Oscillations May Be The Key To What Controlled Ice Ages (http://www.sciencedaily.com/releases/2001/10/011018071615.htm)
ScienceDaily (Oct. 18, 2001) COLUMBUS, Ohio - An international team of scientists reported this week that a rock core drilled from the seafloor off the coast of Antarctica is the first to show cyclic climate changes in polar regions that are linked to cores taken from the ocean bottom in both temperate and tropical zones.
These records show ice sheet advances and retreats that match Milankovitch cycles - variations in the Earth’s orbit around the sun, in the tilt of the Earth’s axis and in the direction the planet’s axis is pointing. The finding, reported in the British journal Nature, suggests a link between these orbital oscillations and the timing of Antarctic ice ages.
The core was drilled in 1998-99 as part of the Cape Roberts Project, an effort by scientists from seven nations to retrieve climate histories trapped in millions of years of sediment beneath the floor of the Ross Sea. Drill sites located just offshore from the Transantarctic Mountains and near McMurdo Station, the main U.S. base in the Antarctic, have retrieved cores from three drill holes. The report in Nature discusses sediments found in the second of these cores. While the Antarctic ice sheets formed approximately 34 million years ago, the parts of the core described in this paper were deposited during a period lasting about 400,000 years, approximately 24.1 to 23.7 million years ago.
Global temperatures at that time were perhaps 3 to 4 degrees C higher than they are today, similar to those predicted for the next century by current climate models that incorporate global warming effects. The amount of carbon dioxide in the air at that time is believed to have been approximately twice current levels.
For years, researchers examining deep-ocean cores from tropical and temperate parts of the oceans have used indirect evidence to propose that variation in the volume of the ice sheets in the polar regions was driven by so-called Milankovitch cycles.
But none of the cores drilled on the Antarctic continental shelf had provided the high-quality data needed to rigorously test that theory. And interpreting changes in polar climate based on evidence recovered so far-removed from the region in question makes many scientists uneasy.
These new findings, however, show that Antarctic ice sheets advanced and retreated at regular intervals during a 400,000-year period between 24.1 and 23.7 million years ago. The records in the core showed the cycles lasted approximately 100,000 years and 40,000 years — the same time spans characteristic of some Milankovitch cycles.
“It appears that the Antarctic ice sheet has responded in a very major and rhythmic way during this period,” explained Peter Webb, professor of geological sciences at Ohio State University and co-chief scientist on the project. “The growth and reduction of the Antarctic ice sheet at its margins is similar to that of the Quaternary Ice Sheets in the Northern Hemisphere.”
That is important since most scientists believe that the more recent formation of the large Quaternary ice sheets, some 2.5 million years ago in the Northern Hemisphere, stockpiled water on the continents and caused sea levels to drop by as much as several hundred feet. Webb says the sea level drop indicated by these new Antarctic core is of similar magnitude.
Overall, the Cape Roberts Project cores record approximately 15 million years of Antarctic history. Within that history, Webb said that the team had identified approximately 46 sediment cycles, each of which contained a similar pattern of sediment layers. Each records a major glacial advance, followed by ice sheet retreat, and concludes when ice advanced again from the land into the into the marine continental shelf area.
“This is exactly what we would expect from a growing and receding ice sheet over time,” explained Larry Krissek, an associate professor of geological sciences at Ohio State and a member of the Cape Roberts team.
What sets the new finding apart from other work is that the three sediment sequences described in the Nature paper contained known time markers that allowed researchers to date them precisely. The time markers included deposits of volcanic ash from eruptions of known dates; microfossils known to live during a specific period; and episodes when the Earth’s polarity was reversed - all elements that helped to date the cores. Previous drill cores lacked the precise dating needed to test any paleoclimatic signal for a potential Milankovitch effect.
Within the Cape Roberts Project drillcores, researchers recognized climate changes that lasted a few tens of thousands of years. That observation let them identify climatic variations dating 17 to 34 million years ago. Previously, that kind of change had only been known in Antarctic ice cores for only the past half-million years.
Both Krissek and Webb were surprised with how rapidly global climate changed, based on the sequences in the core. Like evidence from cores below the seafloor in the North Atlantic, these segments suggest a transition from intense glaciations to a wide-scale glacial retreat may have taken less than 100 years.
“It should catch people’s attention now since the change appears to occur in about a human lifespan,” Krissek said. Both agree that the discovery places polar seafloor core research on a level with similar work from sites in the mid-latitudes, a significant accomplishment given the short time such work has been underway. Significant seafloor drilling for climate records only began in 1972.
“We’ve shown now that the Antarctic continent has a valuable archival record,” Webb said. “Now we need to go to other parts of the continent and see if the entire ice sheet is behaving in this manner, or if our new record reflects only a small part of it.” He added that researchers also must fill in the gap between 17 million years ago and the present, a time when the Earth has been considerably colder than the 15 million years before that.
The Cape Roberts project involves scientists from Australia, Germany, Italy, Netherlands, New Zealand, the United Kingdom and the United States and is supported by the scientific programs of each of those nations. Cores retrieved during the project are divided and stored at two sites - the Alfred Wegener Institut in Bremerhaven, Germany and Florida State University.
