Mines could provide geothermal energy (7/29/2009)

Mines could provide geothermal energyMine shafts on the point of being closed down could be used to provide geothermal energy to local towns. This is the conclusion of two engineers from the University of Oviedo, whose research is being published this month in the journal Renewable Energy. The method they have developed makes it possible to estimate the amount of heat that a tunnel could potentially provide. ...> Full Article


Hydrocarbons in the deep Earth? (7/28/2009)

Hydrocarbons in the deep Earth?Oil and gas started out as living organisms that died, were compressed, and were heated under layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could have been created deeper in the mantle and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under conditions of the upper mantle. ...> Full Article


Rainfall to decrease over Iberian Peninsula (7/27/2009)

Rainfall to decrease over Iberian PeninsulaScientists have recorded a decline in winter precipitation over the past 60 years in Spain, and they now forecast that precipitation will also decrease in spring and summer. A team from the Pyrenean Institute of Ecology has studied rainfall data from 1950 to 2006 and the climate projections for coming decades, showing that less rain will fall in future over the Iberian Peninsula. However, precipitation will continue to be more frequent in winter than in spring and summer. ...> Full Article


Geoengineering: The promise and its limits (7/26/2009)

Four expert speakers attended an event organized by the Institute of Physics, the Royal Society of Chemistry and the Royal Academy of Engineering on July 15 at the House of Commons to address an audience curious about geoengineering the planet to combat the effects of global warming; the solutions it offers and the concerns it raises. ...> Full Article


Tiny diamonds on Santa Rosa Island give evidence of cosmic impact (7/25/2009)

Tiny diamonds on Santa Rosa Island give evidence of cosmic impactNanosized diamonds found just a few meters below the surface of Santa Rosa Island off the coast of Santa Barbara provide strong evidence of a cosmic impact event in North America approximately 12,900 years ago, according to a new study by scientists. Their hypothesis holds that fragments of a comet struck across North America at that time. ...> Full Article

New geothermal heat extraction process to deliver clean power generation (7/24/2009)

A new method for capturing significantly more heat from low-temperature geothermal resources holds promise for generating virtually pollution-free electrical energy. Scientists at the US Department of Energy's Pacific Northwest National Laboratory will determine if their innovative approach can safely and economically extract and convert heat from vast untapped geothermal resources. ...> Full Article


Ancient global warming episode holds clues to future climate (7/23/2009)

Ancient global warming episode holds clues to future climateA global warming event 55 million years ago cannot be solely explained by atmospheric carbon dioxide levels, a study published in Nature Geoscience shows. Richard Zeebe from the University of Hawaii and his team highlight gaps in scientists' understanding of impacts from intense and rapid climate change. Carbon dioxide released at the time can only account for a fraction of the temperature rise. So far unknown mechanisms must have contributed significantly to the ancient warming. ...> Full Article

Early initiation of Arctic sea-ice formation (7/22/2009)

Significant sea ice formation occurred in the Arctic earlier than previously thought is the conclusion of a study published this week in Nature. "The results are also especially exciting because they suggest that sea ice formed in the Arctic before it did in Antarctica, which goes against scientific expectation," says scientific team member Dr. Richard Pearce of the University of Southampton's School of Ocean and Earth Science based at the National Oceanography Center, Southampton. ...> Full Article

Arctic sea ice images derived from classified data should be made public (7/21/2009)

Hundreds of images derived from classified data that could be used to better understand rapid loss and transformation of Arctic sea ice should be immediately released and disseminated to the scientific research community, says a new report from the National Research Council. ...> Full Article


'Motion picture' of past warming paves way for snapshots of future climate change (7/20/2009)

By accurately modeling Earth's last major global warming -- and answering pressing questions about its causes -- scientists led by a University of Wisconsin-Madison climatologist are unraveling the intricacies of the kind of abrupt climate shifts that may occur in the future. ...> Full Article

Earth's most prominent rainfall feature creeping northward (7/4/2009)

Earth's most prominent rainfall feature creeping northwardThe rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years. If the band continues to migrate at just less than a mile a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator may be starved of freshwater by midcentury or sooner. ...> Full Article


Plants save the earth from an icy doom (7/3/2009)

Plants save the earth from an icy doomFifty million years ago, the North and South poles were ice-free and crocodiles roamed the Arctic. Since then, a long-term decrease in the amount of CO2 in the atmosphere has cooled the Earth. Researchers at Yale University, the Carnegie Institution of Washington and the University of Sheffield now show that land plants saved the Earth from a deep frozen fate by buffering the removal of atmospheric CO2 over the past 24 million years. ...> Full Article
