The National Science Foundation has funded a study to determine past climates by studying tree rings. Environmental students from Arizona studied bristlecone pine trees to determine aspects about the Earth´s climates during the Paleo age. The study of tree growth rings to understand Earth´s past climate is called dendrochronology. As each year passes, trees add growth rings around their trunks. These dendrochronologists study these rings to gain all sorts of information not only...

Reintroduction of the American Chestnut tree after billions died due to blight could be accomplished more effectively thanks to a software tool developed and recently tested by the University of Cincinnati. The death of the American Chestnut due to an Asian bark fungus accidentally introduced to the United States had profound environmental and economic consequences since the tree was highly valued for its strong, workable lumber and a variety of wildlife from deer to birds to bears relied...

Ancient Forest In NY More Diverse Than Scientists Thought

[ Watch the Video ] After unearthing a previously unknown portion of one of the planet´s earliest known forests, archeologists say the fossils of 385-million-year-old trees reveal a far more diverse ecosystem than researchers had previously thought existed. Partially uncovered by quarry workers in 1870, the ancient forest beneath the tiny town of Gilboa, N.Y. has been of intense interest to paleobotanists since the 1920s. Dating back to the Devonian Period, researchers early on...

Nation's Urban Forests Losing Ground

National results indicate that tree cover in urban areas of the United States is declining at a rate of about 4 million trees per year, according to a U.S. Forest Service study published recently in Urban Forestry & Urban Greening. Tree cover in 17 of the 20 cities analyzed in the study declined while 16 cities saw increases in impervious cover, which includes pavement and rooftops. Land that lost trees was for the most part converted to either grass or ground cover, impervious cover...

Tree Rings May Underestimate Climate Response To Volcanic Eruptions
2012-02-06 05:45:55

Some climate cooling caused by past volcanic eruptions may not be evident in tree-ring reconstructions of temperature change because large enough temperature drops lead to greatly shortened or even absent growing seasons, according to climate researchers, who compared tree-ring temperature reconstructions with model simulations of past temperature changes. "We know these tree rings capture most temperature changes quite well," said Michael Mann, professor of meteorology and geosciences and...


Word of the Day
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
