Meteoric Research at Lake El'gygytgyn: the most continuous archive of information about past climate change from the entire Arctic borderlands
The paper is called: Pliocene Warmth, Polar Amplification, and Stepped Pleistocene Cooling Recorded in NE Arctic Russia.
Like reading a detective novel: the most continuous archive of information about past climate change from the entire Arctic borderlands - from ScienceDaily:
"While existing geologic records from the Arctic contain important hints about this time period, what we are presenting is the most continuous archive of information about past climate change from the entire Arctic borderlands. As if reading a detective novel, we can go back in time and reconstruct how the Arctic evolved with only a few pages missing here and there," says
A huge meteorite, perhaps a kilometer in diameter! Telling a story going back more than 3 million years...
"Lake E" (that's easier) was formed 3.6 million years ago when a meteorite, perhaps a kilometer in diameter, hit the Earth and blasted out an 11-mile (18 km) wide crater. It has been collecting sediment layers ever since. Luckily for geoscientists, it lies in one of the few Arctic areas not eroded by continental ice sheets during ice ages, so a thick, continuous sediment record was left remarkably undisturbed. Cores from Lake E reach back in geologic time nearly 25 times farther than Greenland ice cores that span only the past 140,000 years.The Arctic was very warm way back in time, when CO2 was not much higher than those of today...a sign of things to come:
"One of our major findings is that the Arctic was very warm in the middle Pliocene and Early Pleistocene [~ 3.6 to 2.2 million years ago] when others have suggested atmospheric CO2 was not much higher than levels we see today. This could tell us where we are going in the near future. In other words, the Earth system response to small changes in carbon dioxide is bigger than suggested by earlier climate models," the authors state.The research doesn't just provide answers it raises some intriguing new questions, the answers to which will add to knowledge about past climatic events:
The sediment core also reveals that even during the first major "cold snap" to show up in the record 3.3 Million years ago, temperatures in the western Arctic were similar to recent averages of the past 12,000 years. "Most importantly, conditions were not 'glacial,' raising new questions as to the timing of the first appearance of ice sheets in the Northern Hemisphere," the authors add.
An Incredible Achievement, Phenomenal and DifficultThe Guardian article gives a glimpse into the difficulties faced by the scientists (my bold):
"It's a phenomenal record," said Prof Peter Sammonds, at University College London. "It is also an incredible achievement [the study's work], given the remoteness of the lake." Sixteen shipping containers of equipment had to be hauled 90km over snow by bulldozers from the nearest ice road, used by gold miners.
But this incredible achievement, this phenomenal, difficult and dangerous work was all for nothing if you follow the deniosaurs. They could have just asked Tony!
DuKE™ 1: Anthony Watts Dimly DuKEs** it OutAnthony draws on his years of anti-science blogging and solid paleo research (not!) and decides that the "researcher" (he doesn't say which of the 16 researchers) forgot about the Isthmus of Panama. (Read together with Lunt et al (2008) here.) This researcher, according to Anthony "simply skipped over this important detail is pushing the idea that CO2 was the only issue."
Scientists "don't know nuffin'" - if only they'd asked TonyI expect Anthony's trying to say that not only all the specialists conducting this research, but the editors of Science and the paper's reviewers "don't know nuffin'". Oh my! If only they'd remembered (or just asked Tony). It would have saved them years of work.
Warning: The Auditor is on the warpathAnthony goes on to issue this dire warning that The Auditor is On the Warpath, which will no doubt leave all the scientists quaking in their boots and wishing they'd never embarked on such a foolish venture:
I’m sure Steve McIntyre will be interested in getting a look at the sediments and the dating methods to see if there are errors there.
Lately, it seems that paleo research has made some very broad assumptions, and almost always in the favor of the theory.Duh!
DuKE™ 2: The Australian Raises the White Flag
On another front, Graham Readfearn has devoted some space to pointing out how Graham Lloyd of/and The Australian are so far into science denial that they are now "too fringe for Monckton". Earlier this week Lloyd wrote a piece regurgitating some idiocy promoted five years ago by the Dragon Slayers (who don't 'believe in' greenhouse gases). He reckons we might be "heading for an ice age". Wow!
Can they fall any lower?
Tim Lambert kept up with The Australian's War on Science for many years. Seems to me The Australian has raised the white flag and signalled it has lost its war. Now they are reduced to pushing fantasies that are even too much for the potty peer.
Time for Barry Bickmore to come up with the First and Second Laws of Graham Lloyd and The Australian.
