Tree Stories: How Tree Rings Reveal Extreme Weather Cycles
New BYU study documents extreme 16-year drought in Utah BYU Geography Professor Matt Bekker uses dendrochronology (dendro=tree, chronology=time) to reveal extreme weather patterns in the Western U.S. By taking core samples from trees and measuring tree rings, the BYU research team can correlate patterns in tree rings to weather cycles. The process allows researchers to extend the known climatic history of a region hundreds of years beyond the written history. Such information can be used by water managers to prepare for possible drought cycles in the future. Data collected in Utah revealed an extreme period of drought that spanned 16 years; the event, which occurred in the year 1703, was previously unknown to climatologists. See more at: http://news.byu.edu/archive14-apr-dendrochronology.aspx Video produced by BYU News Producer Julie Walker Photography Brian Wilcox Editor Michael Gordon NEWS RELEASE FROM MAY 1, 2014: TREE RINGS REVEAL NIGHTMARE DROUGHTS IN THE WEST If you think the 1930s drought that caused The Dust Bowl was rough, new research looking at tree rings in the Rocky Mountains has news for you: Things can get much worse in the West. In fact the worst drought of this century barely makes the top 10 of a study that extended Utah's climate record back to the year 1429. With sandpaper and microscopes, Brigham Young University professor Matthew Bekker analyzed rings from drought-sensitive tree species. He found several types of scenarios that could make life uncomfortable in what is now the nation's third-fastest-growing state: - Long droughts: The year 1703 kicked off 16 years in a row with below average stream flow. - Intense droughts: The Weber River flowed at just 13 percent of normal in 1580 and dropped below 20 percent in three other periods. - Consecutive worst-case scenarios: The most severe drought in the record began in 1492, and four of the five worst droughts all happened during Christopher Columbus' lifetime. "We're conservatively estimating the severity of these droughts that hit before the modern record, and we still see some that are kind of scary if they were to happen again," said Bekker, a geography professor at BYU. "We would really have to change the way we do things here." Modern climate and stream flow records only go back about 100 years in this part of the country, so scientists like Bekker turn to Mother Nature's own record-keeping to see the bigger picture. For this study, the BYU geographer took sample cores from Douglas fir and pinyon pine trees. The thickness of annual growth rings for these species is especially sensitive to water supply. Using samples from both living and dead trees in the Weber River basin, the researchers built a tree-ring chronology that extends back 585 years into Utah's natural history. Modern stream flow measurements helped them calibrate the correlation between ring thickness and drought severity. As Bekker and his co-authors report in the Journal of the American Water Resources Association, the west's climate usually fluctuates far more than it did in the 1900s. The five previous centuries each saw more years of extremely dry and extremely wet climate conditions. "We're trying to work with water managers to show the different flavors of droughts this region has had," said Bekker. "These are scenarios you need to build into your models to know how to plan for the future." Bekker collaborated with researchers from the U.S. Forest Service, Columbia University and Utah State University. The team is currently working on a climate reconstruction based on tree rings that date back more than 1,000 years. Read more here: http://news.byu.edu/archive14-apr-dendrochronology.aspx
Tree Ring Dating Debunked (Dendrochronology Uncensored)
Tree Ring Dating (Dendrochronology) Debunked by Lord Christopher Monckton. Dendrochronology or tree-ring dating, is the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. This has three main areas of application: paleoecology, where it is used to determine certain aspects of past ecologies (most prominently climate); archaeology and the history of art and architecture, where it is used to date old panel paintings on wood, buildings, etc.; and radiocarbon dating, where it is used to calibrate radiocarbon ages. In some areas of the world, it is possible to date wood back a few thousand years, or even many thousands. As of 1995, the maximum reported fully anchored chronologies is ~11,000 years before the present.

Relative and Absolute Dating
Relative and Absolute Dating Dr. Michael Wilson, Geology Department, Douglas College "Relative dating would be the placement of something in a sequence. So if we establish a sequence for an area we simply need to know what came first, then what came next, etc. For example, in a sequence of stratified deposits, laid down by a river or deposited by wind, we are talking about superposition as the basis for that sequence. Superposition means that the oldest deposits would be at the bottom and the youngest deposits would be on the top, in kind of layer cake fashion. So that principal has served us very well. If we have no means by which to absolutely date materials, we can still work out a sequence of events – that can be extremely important. So relative dating was really the only mechanism that people had available for dating archaeological and paleontological materials until the 20th century. There were a few absolute dating methods, and by absolute, I mean dating with respect to a measured time series. In other words, being able to place something in terms of a calendar– dating in terms of years. There were a few techniques that could be used in certain situations – counting of annual cycles in glacial lakes – we call these cycles “varves”. Counting those annual cycles of sediment deposition could actually allow us to determine the age of these lake deposits if they continued up to the present day. Or the use of tree ring dating – counting the rings in trees if we have logs preserved in a fairly recent site and could relate it to some known historic trees. Those were absolute dating techniques. But for the most part, until the 20th century, relative dating was the basis for archaeological, paleontological and geological dating."

Evolution Debunked Pt3: Tree Ring Dating not Logical Beyond 3500 years
Tree Ring dating was a major breakthrough in dating in dating the earth and human artifacts. This has been scientifically dated to about 3500 years. After this, the "science" is a good effort, but fails. It fails based upon a simple principle: trees grow more densely when crowded out by more mature trees. Stated another way, when the canopies of mature trees overshadow saplings, those saplings grow to be more dense. Charles Lyell (a liar) invented a theory called Stratigraphy. This was the mother of "millions and billions of years". Geology has based their assignment of dates to layers of earth based on Stratigraphy. Archeology also based their system on Stratigraphy. Today, If you ask a Geologist how a layer of earth is dated, they will tell you it is based upon the dating of artifacts found therein. If you ask an Archeologist how the artifacts are dated, he will tell you it is dated according to the layer of earth in which it was discovered. ???????????????????????????????????????? ?????? That is a circular argument. They both date based on each other. The real origin of dating goes back to Stratigraphy and Charles Lyell.

Ancient sentinels and the secrets locked away in their tree-rings
The explosive eruption of the volcano Thera on Santorini more than 3,400 years ago buried the Minoan settlement on the island in a layer of ash and pumice more than 130 feet (40 meters) deep. The effects of the eruption were felt as far away as Egypt and what is now Istanbul in Turkey. New analyses that use tree rings could settle the long-standing debate about when Thera erupted by resolving discrepancies between archeological and radiocarbon methods of dating the eruption, according to new University of Arizona-led research. “It’s about tying together a timeline of ancient Egypt, Greece, Turkey and the rest of the Mediterranean at this critical point in the ancient world — that’s what dating Thera can do,” said lead author Charlotte Pearson, an assistant professor of dendrochronology at the UA Laboratory of Tree-Ring Research.

Lord of the Tree Rings - Science Nation
David Stahle travels to ancient forests around the world, collecting tree rings to learn more about major climate and historical events dating back hundreds and thousands of years. With help from the National Science Foundation, he uses Dendrochronology, or tree-ring dating, to get a snapshot of climate change over time. Stahle can also determine things like the socioeconomic impact of droughts. In fact, in 1998, he made the front page of the New York Times with his discovery that drought could have contributed to the disappearance of colonists in Jamestown. He also found that 1587 was the driest year in 800 years. Stahle runs the Tree-ring Lab at the University of Arkansas and what he and fellow tree-ring researchers are learning is that a trend of global warming began in the 1800s and continues today, brought about by changes in tropical sea surface temperatures of no more than a few tenths of a degree Celsius. Today Stahle is working with hydrologists and government planners in California and throughout Mexico to plan for drought and climate change events.

Tree Rings
Original file date: Sun, 29 Mar 2015, ID:nyr68x Trees respond to water like all living things, and they make useful records of dry and wet seasons. When it’s wet, the trees flourish. When it’s dry, they’re stressed. All those responses show up in a tree’s rings. Using those ring records, dendrochronologists have been able to take a look back in time and get a sense of water and drought in the West. Last month, scientists at Utah State University, Brigham Young University and The U.S. Forest Service announced they’d traced the Bear River’s stream flow back 1,200 years. That’s long before Mormon pioneers started building the first towns and cities in the area, and longer than any other tree-ring record in northern Utah to date. “One of the key messages is there is no ‘normal,’” said Roger Kjelgren, a professor and plant scientist at USU. “(Northern Utah) really is like a grandfather clock. It oscillates back and forth, moving between orbiting around a dry period and then shifting and oscillating back to a wet period.” The trick is lining up all that wet-dry variation with climate models. Climate models do a good job at predicting temperatures, but they’re not as good at predicting future precipitation. That’s where the trees can help. “I wouldn’t say it’s a match made in heaven, but it’s kind of a jigsaw-puzzle fit, taking the past tree record from the tree rings and combining it with the climate models to get an idea of these cycles,” Kjelgren said. During a wet season, trees drink in water and grow proportionally. As the season dries, they harden and cell walls get darker. That’s how tree rings form. During dry years, the rings will be tiny, sometimes requiring a microscope to see. The Bear River tree-ring study went back 1,200 years with the help of Utah juniper trees, a particularly finicky and telling species when it comes to water. “It maintained its sensitivity going back in time,” said Justin DeRose, a U.S. Forest Service scientist and the lead author of the study. “So we decided to go with Utah juniper against the advice of some folks.” When dendrochronologists study trees, they don’t just look at live ones. They scavenge for dead wood in the area, then line up the tree-ring records of dry and wet periods. The process, called cross-dating, helps scientists take the chronology back further in time. “It also helps us work out any problems if there are particularly bad years, and some trees deiced not to grow a ring on a part of the stem which is called an absent ring, by having a couple of cores per tree or cross sections, can find out where those occur across multiple trees,” DeRose said. Juniper are “sensitive” because their variability in tree-ring width is high compared to other trees. “For Utah juniper, everything’s’ this year. It lives for today, it’s very Zen-like,” Kjelgren said. “It lives in the now, and if there’s no water it doesn’t grow. If there is water, particularly in the springtime, it puts everything it can into foliage and trunk growth.” In drier climates, like the Southwest, juniper trees often have false rings because the region typically has two wet seasons — spring runoff and summer monsoons. The region is also prone to long drought, which means junipers won’t grow any rings at all. That’s not the case in northern Utah. “Up here, we have one distribution of precipitation — we get precipitation in the winter, we get snowmelt, then in the summer it’s dry,” De Rose said. “It’s one of the reasons we love living here. Utah juniper  thrives in dry, rocky areas, where older specimens are often better preserved. It’s also one of the most prolific trees species in the state.  The ancient Utah juniper DeRose analyzed in his study fo...

Tree Rings
The rings that a tree forms in its wood, are a measure of the tree's growth and age. A new ring is formed each year, so you can tell how old a tree was by counting the rings on the stump. The size and spacing of the rings relate to the growing conditions during the tree's lifetime. A series of narrow rings indicates a period of drought or competition from neighboring trees which slowed growth while wide, evenly spaced rings means growing conditions were good. Fire and insect damage leave scars, and some trees even show scars from animal scratchings. http://mdc.mo.gov/conmag/1996/10/70.html
