Long before SUVs, Arctic was warm enough to support mastodons; leafy vegetation Written by CCD Editor on 18 December 2014. In a new paper published in the Proceedings of the National Academy of Sciences, a team reveals that 125,000 years ago the Arctic was once a "holiday home" for mastodons, a forest-dwelling animal with a preference for "heaps of leafy goods" and a warm climate. Instead of dying out from rapid climate change or over hunting by humans as previously thought, the paper shows they simply moved south when the Arctic grew colder and they eventually died out.

Ancient relative of the elephant ‘holidayed in warm Arctic 125,000 years ago’Scientists have puzzled over this chronology as mastodons, which looked similar to modern-day Asian elephants, are known to have had a preference for forests and wetlands filled with heaps of leafy goods. In a paper published today in the Proceedings of the National Academy of Sciences, an international team suggests that the Arctic and Subarctic were just temporary “holiday homes” for mastodons when the local climate was warm around 125,000 years ago. When the cold weather returned, their populations moved much further to the south, where the paper suggests they ultimately died out about 10,000 years ago. The findings debunk theories about over hunting by early humans being the reason for their disappearance from this region as these new dates show they were wiped out locally before human colonisation. Researchers from the University of Oxford and the University of California radiocarbon dated collagen from 36 fossil teeth and bones of American mastodons from Alaska and Yukon. The dates for all of the fossils were older than previously thought. Alaska and Yukon were part of an ancient region known as eastern Beringia which is thought to have connected Asia with North America at various times. When taking mastodon habitat preferences and other ecological and geological information into account, the results show that mastodons probably only lived in eastern Beringia for a relatively short time when temperatures were as warm as they are today. ~snip~ www.heritagedaily.com/2014/12/ancient-relative-elephant-holidayed-warm-arctic-125000-years-ago/106077

Science and academia has some really major problems. I am saying this because it is triggered by the sentence: An interesting quote. Follow that up by these and try to guess what 'field' of research these two quotes come from: "In other words, if the facts do not agree with the favored theory, then such facts, even an imposing array of them, must be discarded."and "This supports the primary point we are trying to make in ###########, namely, that there exists in the scientific community a knowledge filter that screens out unwelcome evidence."
Yes you guessed right those quotes are about Archaeology They come from: Cremo, Michael (2011-01-28). Forbidden Archaeology. Torchlight Publishing Inc. I have found similar quotes in all fields of science. Climate science policy based data making just happens to be being used to support political power grabbing. But the approach of hypotheses and models trumping observations seems to be disturbingly common.

But the approach of hypotheses and models trumping observations seems to be disturbingly common. I would have to agree. Though it is mot new, it seems to be getting worse.

I think this is posted elsewhere but was worth a repost here. Matt Ridley Policy-based evidence makingPublished on Tuesday, December 09, 2014, updated Wednesday, December 10, 2014 Science is being corrupted by political bias My column in the Times, with post-scripts: As somebody who has championed science all his career, carrying a lot of water for the profession against its critics on many issues, I am losing faith. Recent examples of bias and corruption in science are bad enough. What’s worse is the reluctance of scientific leaders to criticise the bad apples. Science as a philosophy is in good health; science as an institution increasingly stinks. The Nuffield Council on Bioethics published a report last week that found evidence of scientists increasingly “employing less rigorous research methods” in response to funding pressures. A 2009 survey found that almost 2 per cent of scientists admitting that they have fabricated results; 14 per cent say that their colleagues have done so. This month has seen three egregious examples of poor scientific practice. The most recent was the revelation in The Times last week that scientists appeared to scheme to get neonicotinoid pesticides banned, rather than open-mindedly assessing all the evidence. These were supposedly “independent” scientists, yet they were hand in glove with environmental activists who were receiving huge grants from the European Union to lobby it via supposedly independent reports, and they apparently had their conclusions in mind before they gathered the evidence. Documents that have recently come to light show them blatantly setting out to make policy-based evidence, rather than evidence-based policy. ~snip~ www.rationaloptimist.com/blog/policy-based-evidence-making.aspx

What is worrying to me is that temps are expected to match those of the inter glacial ,125,000yrs ago, before the end of the century? When we look at the state of global ice back then it also begs the question "why are predicted sea level changes so low?" when we know what how much ice was absent and what that means for global sea levels.
It's interesting to figure just how the basin was over that period with 'tropical' creatures and plants in the record there? Did we just have a winter season of heavy fogs, trapping in heat at the surface, once winter nights arrived ( and the ocean began to shed its heat).
What happens to the temperate zones when we have no cold to import over winter? We don't need to 'rapidly warm' only for our moderating cold outbreaks to become absent.

What is worrying to me is that temps are expected. . . . . you probably shouldn't worry about the "expectations" of climate models that so far have been wrong about everything. Actually Obama's promise that everybody could keep their current healthcare plan has been far more correct than the climate models because at least a few people were able to keep their health plan.

On the run up to 2000...alot of people expected their computers would go phut.... Acidohm, a lot would have phutted had not concentrated remediation efforts been undertaken. The corporation where I worked spent countless man hours testing, re-coding in house apps that did not comply, retiring apps that could not be fixed, testing third-party (eg, Micro$oft) apps to confirm manufacturers' claims, testing software-controlled machinery, etc. In the end, we had a few minor problems but nothing mission critical. Luckily for me, Clipper supported all dates in the range 01/01/0100 to 12/31/2999 and I needed to make no changes to any code.

Fair enough...at the time I lived with a computer programmer who laughed all the way to the bank....He always gave me the impression he was committing legal theft!

It's exactly the same here is Australia. If only I could find the Gergis/Karoly paper, I'd post a reference.

Finland is close to the Arctic circle with meridonal jet streams it would stay cool, but with latitudinal jet streams, warm air is being dragged towards the poles and Finland gets warmer. At the same time where the large Rossby wave loops take the jet streams equatorwards areas like the Midwest and the Levant are colder than normal. The news item was a desperate attempt to come up with a warming headline.
