Ice sheets can retreat 'in a geologic instant,' study of prehistoric glacier shows (6/24/2009)

Modern glaciers, such as those making up the Greenland and Antarctic ice sheets, are capable of undergoing periods of rapid shrinkage or retreat, according to new findings by paleoclimatologists at the University at Buffalo. ...> Full Article


Close relationship between past warming and sea-level rise (6/23/2009)

Scientists from the National Oceanography Centre, Southampton, along with colleagues from Tuebingen and Bristol have reconstructed sea-level fluctuations over the last 520,000 years. Comparison of this record with data on global climate and CO2 levels from Antarctic ice cores suggests that even stabilization at today's CO2 levels may commit us to much greater sea-level rise over the next couple of millennia than previously thought. ...> Full Article


Ancient drought and rapid cooling drastically altered climate (6/22/2009)

Ancient drought and rapid cooling drastically altered climateTwo abrupt and drastic climate events, 700 years apart and more than 45 centuries ago, are teasing scientists who are now trying to use ancient records to predict future world climate. The events -- one, a massive, long-lived drought believed to have dried large portions of Africa and Asia, and the other, a rapid cooling that accelerated the growth of tropical glaciers -- left signals in ice cores and other geologic records from around the world. ...> Full Article


When palm trees gave way to spruce trees (6/21/2009)

When palm trees gave way to spruce treesOne long-standing climate puzzle relates to the Late Eocene and Early Oligocene. Profound changes were underway. Globally, carbon dioxide levels were falling and the hothouse warmth of the dinosaur age and Eocene Period was waning. In Antarctica, ice sheets had formed and covered much of the southern polar continent. But what exactly was happening on land, in northern latitudes? An international team that included Dr. David Greenwood, an NSERC-funded researcher at Brandon University, now provides some of the very first detailed answers. ...> Full Article

Sediment yields climate record for past half-million years (6/17/2009)

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years. The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period. ...> Full Article


The Earth's magnetic field remains a charged mystery (6/16/2009)

Professor Gregory Ryskin from the McCormick School of Engineering and Applied Science at Northwestern University in Illinois, US, has defied the long-standing convention by applying equations from magnetohydrodynamics to our oceans' salt water (which conducts electricity) and found that the long-term changes (the secular variation) in the Earth's main magnetic field are possibly induced by our oceans' circulation. ...> Full Article


Greenland ice sheet larger contributor to sea-level rise (6/13/2009)

Predicted ground motions for great earthquake in Pacific Northwest: Seattle, Victoria and Vancouver (6/12/2009)

A new study evaluates expected ground motion in Seattle, Victoria and Vancouver from earthquakes of magnitude 7.5 - 9.0, providing engineers and policymakers with a new tool to build or retrofit structures to withstand seismic waves from large "subduction" earthquakes off the continent's west coast. ...> Full Article


Surprise: Typhoons trigger slow earthquakes (6/11/2009)

Surprise: Typhoons trigger slow earthquakesScientists have made the surprising finding that typhoons trigger slow earthquakes, at least in eastern Taiwan. Slow earthquakes are non-violent fault slippage events that take hours or days instead of a few brutal seconds to minutes to release their potent energy. The researchers discuss their data in a study published the June 11 issue of Nature. ...> Full Article


Cantabrian cornice has experienced 7 cooling and warming phases over past 41,000 years (6/5/2009)

The examination of the fossil remains of rodents and insectivores from deposits in the cave of El Miron, Cantabria, has made it possible to determine the climatic conditions of this region between the late Pleistocene and the present day. In total, researchers have pinpointed seven periods of climatic change, with glacial cold dominating during some of them, and heat in others. ...> Full Article


Team starts first-ever Tennessee Valley earthquake survey (6/4/2009)

A new research project at the University of Tennessee, Knoxville, funded by the Nuclear Regulatory Commission will provide the first-ever record of seismic activity in the Tennessee Valley, providing not only new information on past quakes but insight into future activity.Led by Robert Hatcher, a team will explore sites from just north of Knoxville, Tenn., to just north of Rome, Ga. The area, known as the East Tennessee Seismic Zone, is the second most seismically active area in the eastern US. ...> Full Article


Melting Greenland ice sheets may threaten Northeast United States, Canada (6/3/2009)

A melting of the Greenland ice sheet this century may drive more water than previously thought toward the already threatened coastlines of New York, Boston, Halifax and other cities in the northeastern United States and in Canada, according to new research led by NCAR. ...> Full Article


Meteorite bombardment may have made Earth more habitable, says study (6/2/2009)

Large bombardments of meteorites approximately four billion years ago could have helped to make the early Earth and Mars more habitable for life by modifying their atmospheres, suggests the results of a paper published today in the journal Geochimica et Cosmochima Acta. ...> Full Article


Height of large waves changes according to month (6/1/2009)

A team of researchers from the University of Cantabria has developed a statistical model that makes it possible to study the variability of extreme waves throughout the year, according to the journal Coastal Engineering. The study has shown that there are seasonal variations in the height of waves reaching Spain's coasts, and stresses the importance of this data in planning and constructing marine infrastructures. ...> Full Article
