U of M physicist reads the history of the solar system in grains of comet dust
Four years ago, NASA's Stardust spacecraft chased down a comet and collected grains of dust blowing off its nucleus. When the spacecraft Comet Wild-2 returned, comet dust was shipped to scientists all over the world, including University of Minnesota physics professor Bob Pepin.   view more (2008-01-04)

Pine Bark Beetles Affecting More than Forests
Pine bark beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.   view more (2008-09-25)

DARESBURY REPORT SHOWS ROAD TO CLEANER TRANSPORT
Future global targets on reducing emissions of greenhouse gases may be more easily met thanks to new research on catalysts for fuel cells, published today in the new annual report from Daresbury Laboratory’s Synchrotron Radiation Department. Tough emission targets are driving the development... view more (2000-12-11)

ESA providing Kyoto estimates of French Guiana's tropical forests
ESA is providing data from its Earth observation satellites to monitor the tropical forests in French Guiana and help the French government meet its obligations under the international Kyoto Protocol agreement on global warming. Like all the so-called "Annex I" signatories to the Kyoto... view more (2003-06-05)

More than a meteor likely killed dinosaurs 65 million years ago
Growing evidence shows that the dinosaurs and their contemporaries were not wiped out by the famed Chicxulub meteor impact alone, according to a paleontologist who says multiple meteor impacts, massive volcanism in India and climate changes culminated in the end of the Cretaceous Period.   view more (2006-10-27)

Argonne breakthrough may revolutionize ethylene production
A new environmentally friendly technology created by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory may revolutionize the production of the world's most commonly produced organic compound, ethylene.   view more (2008-02-06)

When will India have fusion power plants?
What role could fusion power plants play in the future energy supply of India - one of the world's most highly populated and rapidly expanding countries? How might India's overall energy requirements develop till the year 2100, what technologies will cover them, and what influence will this have on... view more (2002-03-05)

Low-cost reusable material could facilitate capture of carbon dioxide from power plants
Researchers have developed a new, low-cost material for capturing carbon dioxide (CO2) from the smokestacks of coal-fired power plants and other generators of the greenhouse gas. Produced with a simple one-step chemical process, the new material has a high capacity for absorbing carbon dioxide -... view more (2008-03-10)

Yale journal examines the global impact of cities
The global impact of cities is the focus of cutting-edge research in a special issue of Yale's Journal of Industrial Ecology.   view more (2007-06-18)

Ceramic tubes could cut greenhouse gas emissions from power stations
Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material.   view more (2007-08-03)

Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian... view more (2006-09-07)

Arctic sea ice narrowly missed record low in winter 2007, says University of Colorado team
The maximum extent of Arctic sea ice in winter 2007 was the second lowest on satellite record, narrowly missing the 2006 record, according to a team of University of Colorado at Boulder researchers.   view more (2007-04-05)

Energy Lab Sets Aggressive Greenhouse Gas Reduction Goal
The U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has pledged to reduce its greenhouse gas emissions by 75 percent from 2005 to 2009.   view more (2007-12-06)

Global warming doubles rate of ocean rise
Global ocean levels are rising twice as fast today as they were 150 years ago, and human-induced warming appears to be the culprit.   view more (2005-11-28)

Action needed now for Minnesota to reach goals in reducing greenhouse gas emissions by 2015
The state of Minnesota must act now if it wants to reach its Minnesota Next Generation Energy Act goals of reducing greenhouse gas emissions by 15 percent by 2015, according to a team of University of Minnesota transportation and public policy researchers.   view more (2008-07-23)

Fossil wood gives vital clues to ancient climates
New research into a missing link in climatology shows that the Earth was not overcome by a greenhouse period when dinosaurs dominated, but experienced rapid fluctuations in temperature and sea level change that resulted in a balance of the global carbon cycle.   view more (2006-02-24)

"Rational" Meccano
Nanofibrous carbon is interesting by itself: it consists of carbon fibres of 3 to 500 nm in diameter. These fibres can form " cylinders" (which make almost finished polymeric nanotubes), or a system of cones stowed one into the other at a certain angle to the fibre axis, or simply "wrapping... view more (2003-06-16)

Understanding the global carbon budget -- Woods Hole Research Center expert provides insights
As climate change becomes more and more a central issue in local, national, and international discussions, understanding the global carbon budget, and how it influences trends in global warming, will become increasingly crucial.   view more (2007-05-10)

Ocean's 'twilight zone' may be a key to understanding climate change
A major study sheds new light on the role of carbon dioxide once it's transported to the oceans' depths. The research indicates that instead of sinking, carbon dioxide is often consumed by animals and bacteria and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below... view more (2007-04-30)

A warming climate can support glacial ice
New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events.   view more (2008-01-11)

Researchers light up lungs to help diagnose disease
Researchers at the University of Sheffield have developed innovative technology which illuminates a person's lungs and helps clinicians identify if they are functioning correctly. The new technology could result in earlier diagnosis of emphysema and smoking related damage, as well as other lung... view more (2008-04-29)

Woods Hole Research Center scientist furthering discussion of soil carbon decomposition
Significantly more carbon is stored in the world's soils than is present in the atmosphere. In a process called a "positive feedback," global warming may stimulate decomposition of soil organic matter, thus releasing heat-trapping carbon dioxide gas to the atmosphere, possibly causing the... view more (2006-03-09)

Greenhouse Gas Auction Revenues Can Help Cut Md. Electric Use Significantly, Says Study
Maryland officials can reduce electricity use in the state significantly by investing revenues from the Regional Greenhouse Gas Initiative (RGGI) cap-and-trade auctions in energy efficiency programs, says a new study from a University of Maryland-led research team. It adds that neighboring states... view more (2008-10-23)

Calculations favor reducing atmopshere for early Earth
Using primitive meteorites called chondrites as their models, earth and planetary scientists at Washington University in St. Louis have performed outgassing calculations and shown that the early Earth's atmosphere was a reducing one, chock full of methane, ammonia, hydrogen and water vapor.   view more (2005-09-08)
