Scientists Verify Predictive Model for Winter Weather
Scientists have verified the accuracy of a model that uses October snow cover in Siberia to predict upcoming winter temperatures and snowfall for the high- and mid-latitudes of the Northern Hemisphere. view more (2007-08-21)
Laughing Gas in a Vicious Circle
Italian researchers discover another mechanism for the formation of atmospheric N2O Summer smog, the ozone hole, the greenhouse effect – the complex web of chemical reactions in the atmosphere, which leads to manifold environmental problems, is still not fully cleared up. In a tricky way, a single chemical compound is found at the center of... view more... (2001-05-15)
Atmospheric 'Sunshade' Could Reduce Solar Power Generation
The concept of delaying global warming by adding particles into the upper atmosphere to cool the climate could unintentionally reduce peak electricity generated by large solar power plants by as much as one-fifth, according to a new NOAA study. The findings appear in this week's issue of Environmental Science and Technology. view more (2009-03-12)
Mountainous plateau creates ozone 'halo' around Tibet
Not only is the air around the world's highest mountains thin, but it's thick with ozone, says a new study from University of Toronto researchers. view more (2005-12-08)
Small fluctuations in solar activity, large influence on the climate
Our sun does not radiate evenly. The best known example of radiation fluctuations is the famous 11-year cycle of sun spots. Nobody denies its influence on the natural climate variability, but climate models have, to-date, not been able to satisfactorily reconstruct its impact on climate activity. view more (2009-08-28)
Cosmic rays detected deep underground reveal secrets of the upper atmosphere
Cosmic-rays detected half a mile underground in a disused U.S. iron-mine can be used to detect major weather events occurring 20 miles up in the Earth's upper atmosphere, a new study has revealed. view more (2009-01-22)
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)
No quick or easy technological fix for climate change, researchers say
Global warming, some have argued, can be reversed with a large-scale "geoengineering" fix, such as having a giant blimp spray liquefied sulfur dioxide in the stratosphere or building tens of millions of chemical filter systems in the atmosphere to filter out carbon dioxide. view more (2008-12-18)
Scientists uncover solar cycle, stratosphere and ocean connections
Subtle connections between the 11-year solar cycle, the stratosphere, and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research appearing this week in the journal Science. view more (2009-08-28)
Connections among solar cycle, stratosphere and ocean discovered
Subtle connections between the 11-year-solar cycle, the stratosphere and the tropical Pacific Ocean work in sync to generate periodic weather patterns that affect much of the globe, according to research results appearing this week in the journal Science. view more (2009-08-28)
Satellite instrument helps tackle mysteries of ozone-eating clouds
Polar stratospheric clouds have become the focus of many research projects in recent years due to the discovery of their role in ozone depletion, but essential aspects of these clouds remain a mystery. view more (2006-04-11)
A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years. view more (2007-09-19)
Ozone and UV over Europe: no sign of improvement
"The occurrence of ozone mini-holes over Europe increases and any ozone layer recovery could only become measurable around 2010 at the earliest" concludes an assessment report, released today, on European research in the stratosphere. The report concerns loss of ozone, increases in ultraviolet radiation as well as the impact of aircraft... view more... (2002-01-21)
Underground Nuclear Explosions Deteriorate The Ozone Layer
Russian scientists have found one more cause of depletion of the ozone layer. They think that abyssal gases can go to the surface and reach stratosphere, deteriorating the ozone shield. Underground nuclear explosions enforce this process. A geologist Boris Golubov of the Institute of Geosphere Dynamics RAS and a climatologist Grigoriy Kruchenitsky... view more... (2002-08-16)
Scientists want to solve puzzle of excess water vapor near cirrus clouds
A number of researchers in recent years have reported perplexing findings of water vapor at concentrations as much as twice what they should be in and around cirrus clouds high in the atmosphere, a finding that could alter some conclusions about climate change. view more (2006-12-01)
Field project seeks clues to climate change in remote atmospheric region
Scientists are deploying an advanced research aircraft to study a region of the atmosphere that influences climate change by affecting the amount of solar heat that reaches Earth's surface. view more (2008-06-13)
Southern ocean carbon sink weakened
Scientists have observed the first evidence that the Southern Ocean's ability to absorb the major greenhouse gas, carbon dioxide, has weakened by about 15 per cent per decade since 1981. view more (2007-05-21)
A bubbling ball of gas
The Sun is a bubbling mass. Packages of gas rise and sink, lending the sun its grainy surface structure, its granulation. Dark spots appear and disappear, clouds of matter dart up - and behind the whole thing are the magnetic fields, the engines of it all. view more (2009-11-12)
New simulation shows consequences of a world without Earth's natural sunscreen
Nearly two-thirds of Earth's ozone is gone -- not just over the poles, but everywhere. The infamous ozone hole over Antarctica, first discovered in the 1980s, is a year-round fixture, with a twin over the North Pole. The ultraviolet (UV) radiation falling on mid-latitude cities like Washington, D.C., is strong enough to cause sunburn in just five... view more... (2009-03-19)
Environmental science flies higher and wider
A new and highly modified survey aircraft is the latest tool to help study our environment from the skies. The Natural Environment Research Council (NERC) is to lease a Dornier 228 to replace the Piper Navajo Chieftain that has given valiant service in earth observation for the past 16 years. Because the new aeroplane can fly further and carry... view more... (2000-07-25)
