Studies of ancient climates suggest Earth is now on a fast track to global warming
Human activities are releasing greenhouse gases more than 30 times faster than the rate of emissions that triggered a period of extreme global warming in the Earth's past, according to an expert on ancient climates. view more (2006-02-17)
Rising surface ozone reduces plant growth and adds to global warming
Scientists from three leading UK research institutes have today released new findings that could have major implications for food production and global warming in the 21st century. view more (2007-07-26)
Most of Arctic's Near-Surface Permafrost May Thaw by 2100
Global warming may decimate the top 10 feet (3 meters) or more of perennially frozen soil across the Northern Hemisphere, altering ecosystems as well as damaging buildings and roads across Canada, Alaska, and Russia. view more (2005-12-20)
2007 ozone hole 'smaller than usual'
The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements made by ESA's Envisat satellite, this year's ozone loss peaked at 27.7 million tonnes, compared to the 2006 record ozone loss of 40 million tonnes. view more (2007-10-04)
Inside the Ozone Layer
A new atmospheric model is able to quantify man-made versus naturally occurring damage to the stratosphere with an eye toward repairing the diminishing ozone layer that is located within the stratosphere. view more (2006-02-24)
U of M researchers unlock mystery of layer encircling the Earth's core
University of Minnesota associate professor of chemical engineering Renata Wentzcovitch and her team of researchers have confirmed the properties of a mineral (post-perovskite) that may form near the Earth's core in a layer called the D'' region. view more (2006-01-31)
NASA Study Finds Clock Ticking Slower On Ozone Hole Recovery
The Antarctic ozone hole's recovery is running late. According to a new NASA study, the full return of the protective ozone over the South Pole will take nearly 20 years longer than scientists previously expected. view more (2006-06-30)
No safe ground for life to stand on during world's largest mass extinction
The world's largest mass extinction was probably caused by poisonous volcanic gas, according to research published today. view more (2005-12-02)
The inside dope
Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce materials for modern electronics, small amounts of impurities are introduced into silicon - a process called doping. view more (2007-07-27)
Seismologists detect a sunken slab of ocean floor deep in the Earth
Halfway to the center of the Earth, at the boundary between the core and the mantle, lies a massive folded slab of rock that once formed the ocean floor and sank beneath North America some 50 million years ago. view more (2006-05-18)
Titania nanotubes create potentially efficient solar cells
A solar cell, made of titania nanotubes and natural dye, may be the answer to making solar electricity production cost-effective, according to a Penn State researcher. view more (2006-02-08)
Rare high-altitude clouds found on Mars
Planetary scientists have discovered the highest clouds above any planetary surface. They found them above Mars using the SPICAM instrument on board ESA's Mars Express spacecraft. The results are a new piece in the puzzle of how the Martian atmosphere works. view more (2006-08-29)
'Quasicrystal' metal computer model could aid ultra-low-friction machine parts
Duke University materials scientists have developed a computer model of how a "quasicrystal" metallic alloy interacts with a gas at various temperatures and pressures. view more (2005-09-16)
NASA Study Links "Smog" to Arctic Warming
NASA scientists have found that a major form of global air pollution involved in summertime "smog" has also played a significant role in warming the Arctic. view more (2006-03-15)
NASA's AURA satellite peers into Earth's ozone hole
NASA researchers, using data from the agency's AURA satellite, determined the seasonal ozone hole that developed over Antarctica this year is smaller than in previous years. view more (2005-12-07)
As ozone hole approaches annual peak, NASA scientists reveal latest information and images
In 1987, the United States joined several other nations in signing the Montreal Protocol, an international treaty designed to protect the Earth's ozone layer by phasing out the production of a number of substances believed to be responsible for ozone depletion. view more (2006-09-29)
New Era for Norwegian Antarctic Research
The framework conditions for Norwegian research in Antarctica are completely changing. The Norwegian summer station, Troll, will be a year-round station, and the airstrip beside Troll will soon accommodate intercontinental flights. This will have enormous consequences for Norwegian research. From February 2005, year-round operations at the... view more... (2004-08-04)
Ozone layer decline leveling off, according to new study
A new global study involving long-term data from satellites and ground stations indicates Earth's ozone layer, while still severely depleted following decades of thinning from industrial chemicals in the atmosphere, is no longer in decline. view more (2005-08-30)
Volcanic aerosol clouds and gases lead to ozone destruction
Volcanic eruptions destroy ozone and create 'mini-ozone holes', according to two new studies by researchers at the Universities of Cambridge and Oxford. view more (2006-11-09)
Study finds no safe level for ozone
Even at very low levels, ozone-the principal ingredient in smog-increases the risk of premature death, according to a nationwide study to be published in the April edition of the journal Environmental Health Perspectives. view more (2006-02-17)
