[ 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...

Frankincense, a festive fragrance that has been harvested in the wild in the Middle East and the Horn of Africa since ancient times, is declining so dramatically that production of the resin could be halved over the next fifteen years, according to a new study published in the Journal of Applied Ecology. Frankincense is produced by tapping the gum of trees in the Boswellia genus. It is traditionally used in incense and perfumes around the world and is a key part of the Christmas story --...

Image 1 - Climate Change To Blame For Dead African Trees

Trees are dying in the Sahel, a region in Africa south of the Sahara Desert, and human-caused climate change is to blame, according to a new study led by a scientist at the University of California, Berkeley. "Rainfall in the Sahel has dropped 20-30 percent in the 20th century, the world's most severe long-term drought since measurements from rainfall gauges began in the mid-1800s," said study lead author Patrick Gonzalez, who conducted the study while he was a visiting scholar at UC...
