    Visitors to a small log cabin in Kentucky are right to ask: Is it true that Abraham Lincoln slept here? On the eve of Lincoln's 209th birthday tomorrow, Brook Silva-Braga has the answer... "What we're trying to do is authenticate when this cabin was made by using the tree rings in the logs," he replied. Some say our 16th president, born in these hills in 1809, spent some of his childhood in this cabin at Knob Creek. But did he?... So no, Abraham Lincoln did not sleep here in the Knob Creek cabin … or in the "symbolic cabin" at...
  • The Warmist Crisis [Global Warming Becomes a Hot Topic]

    The AMERICAN THINKER ^ | April 9, 2013 | Jonathon Moseley
    The Warmist conspiracy has reached a critical point, with doubters in the establishment speaking out. One of Sweden's top climatologists now admit global temperatures have barely changed (translated from Swedish): "The Earth appears to have cooling properties that exceeds the previous thought ones, and that computer models are inadequate to try to foretell a chaotic object like the climate, where actual observation is the only way to go." In March, a scientific study "Orbital forcing of tree-ring data" found that global warming is caused by that big yellow thing in the sky. Earth's orbit varies over the centuries. Changing distance...

    The Most Important Records For Dating Old Objects Were Just Found In A Japanese Lake Dina SpectorOct. 18, 2012, 2:01 PM Lake Suigetsu in Japan For tens of thousands of years, leaf and twig fossils have remained undisturbed at the bottom of Lake Suigetsu in Japan. By drilling into well-preserved layers of sediment and extracting cores containing those leaves and twigs, researchers have obtained some of the most accurate records of radiocarbon in the atmosphere yet. These records give a precise estimation of how much radioactive carbon there was in the atmosphere in any given year, and could help increase...

    Dr. Tim Ball: A Different Perspective ^ | July 7, 2012 | Dr. Tim Ball
    No, this is not another article about tree rings, hockey sticks, and rewritten history, although that is one tree in the climate forest. A group of scientists dismissed historical evidence and misled the public about temperature trends. Some dismiss their actions as bad science, but the evidence, particularly exposed in the leaked e-mails from the Climatic Research Unit (CRU), indicate differently. Many, including those claiming to be climate scientists were misled because they were experts on another tree in another part of the forest. The Intergovernmental Panel on Climate Change (IPCC) is not studying climatology, but specialists looking at some...

    Americans sweltering in the recent record-breaking heatwave may not believe it - but it seems that our ancestors suffered through much hotter summers in times gone by, several of them within the last 2,000 years. Phew, what a scorcher, Marcus. Let's get in the frigidarium A new study measuring temperatures over the past two millennia has concluded that in fact the temperatures seen in the last decade are far from being the hottest in history. A large team of scientists making a comprehensive study of data from tree rings say that in fact global temperatures have been on a...

    University of Arizona ^ | November 4, 2011
    A new study at the University of Arizona's Laboratory of Tree-Ring Research has revealed a previously unknown multi-decade drought period in the second century A.D.Almost nine hundred years ago, in the mid-12th century, the southwestern U.S. was in the middle of a multi-decade megadrought. It was the most recent extended period of severe drought known for this region. But it was not the first. The second century A.D. saw an extended dry period of more than 100 years characterized by a multi-decade drought lasting nearly 50 years, says a new study from scientists at the University of Arizona.

    Global Warming: Russian analysts accuse Britain's Meteorological Office of cherry-picking Russian temperature data to "hide the decline" in global temperatures. Is Copenhagen rooted in a single tree in Siberia? Michael Mann, a Penn State meteorologist, wrote in Friday's Washington Post that "stolen" e-mails from the University of East Anglia's Climate Research Unit still don't alter the evidence for climate change. Mann, a creator of the discredited hockey-stick graph used in reports from the U.N.'s Intergovernmental Panel on Climate Change to show man-made warming, attacks climate skeptics, including former Alaska Gov. Sarah Palin, saying they "confuse the public." Chutzpah has been...

    JSTOR: Artic and Alpine Research ^ | November 4, 1998 | G.M.McDonald & R.A.Case
    “A 538-yr tree-ring chronology and reconstruction of June temperatures were developed from living and dead Larix dahurica trees. The samples were obtained near the lower Lena River in northern Siberia. Dendrochronological techniques were used to estimate the ages of establishment and mortality of Larix dahurica on the presently treeless uplands and to determine the establishment dates of living trees in the lowlands. ………………………………… It was during the 19th century that the uplands lost much of their tree and soil cover. Recruitment of trees occurred in the lowlands during the 20th century, but trees have not been able to recolonize the...

    Beginning in 2003, I worked with Stephen McIntyre to replicate a famous result in paleoclimatology known as the Hockey Stick graph. Developed by a U.S. climatologist named Michael Mann... ...Steve and I showed that the mathematics behind the Mann Hockey Stick were badly flawed, such that its shape was determined by suspect bristlecone tree ring data. ...a series of other studies published since 1998 had similar shapes, thus providing support for the view that the late 20th century is unusually warm. The IPCC also made this argument in its 2007 report. But the second expert panel, led by statistician Edward...

    This video includes a lengthy series of interviews with Steve McIntyre of Climate Audit. It is an excellent recap of his battles with Mann and the CRU. It was produced by a Finnish group and adds their own tree ring data which support McIntyre. It is in Finnish with English subtitles. The McIntyre interviews are of course in English. It was released recently and appears to have been updated with new information from this past weekend. Click here to open the site.
  • E-Mails Of Climate Researchers Buttress Case Of Warming Fraud

    Junk Science: Hacked e-mails from Britain's Climate Research Unit are only the latest evidence of climate fraud. Just ask NASA's James Hansen about the faking of climate data or EPA employees about the suppression of climate fact. For years, noted scientists and other global warming skeptics have been accused of being on the take, their research tainted and funded by grants from Big Oil and other fossil-fuel interests. Now, it turns out, it's the warm-mongers who are fudging the numbers and concealing the inconvenient truth. We don't know who "Deep Throat" is. But according to an interview in Investigate Magazine's...

    A fascinating, hot-off-the-presses story emerges from the emails that were hacked yesterday from the University of East Anglia's Hadley Climatic Research Centre. It is one of many exchanges that shed light on the priority that the global warming alarmists give to politics and career advancement over science. The story began when Steve McIntyre, the same researcher who was largely responsible for destroying Michael Mann's "hockey stick" graph purporting to show unprecedented warming in the 20th century, turned his attention to a famous article published by Keith Briffa of East Anglia's CRU in 2000. This article analyzed the diameters of tree...

    A big news day. It appears Steve McIntyre (volunteer unpaid auditor of Big-Government-Science) has killed the Hockey Stick a second time. The details are on the last three days of Steve McIntyre’s site Climate Audit, and summed up beautifully on Watts Up. The sheer effrontery and gall appears to be breathtaking. The Briffa temperature graphs have been widely cited as evidence by the IPCC, yet it appears they were based on a very carefully selected set of data, so select, that the shape of the graph would have been totally transformed if the rest of the data had been included....

    March 26, 2002 Tree Rings Show a Period of Widespread Warming in Medieval Age By KENNETH CHANG A new study of old tree rings shows that 1,000 years ago, long before power plants and sport utility vehicles, temperatures across North America, Europe and Asia rose in a period of unusual warmth. In warm weather, trees thrive and grow a thick ring of wood in their trunks for that year. In cold years, growth slows and the tree ring is thin. Temperatures were known to be warm in Europe between 900 and 1100, what is known as the Medieval Warm Period....
