A bumpy shift from ice house to greenhouse
The transition from an ice age to an ice-free planet 300 million years ago was highly unstable, marked by dips and rises in carbon dioxide, extreme swings in climate and drastic effects on tropical vegetation, according to a study published in the journal Science Jan. 5.   view more (2007-01-05)

Rising carbon dioxide levels increase risks to satellites
Climate change is widely attributed to the build-up of greenhouse gases, such as carbon dioxide, in the Earth's atmosphere. However, scientists from the School of Engineering Sciences at the University of Southampton have shown that the impact of carbon dioxide is being felt in space too.   view more (2005-04-18)

HOW TREES CHANGED THE WORLD
Before 380 million years (Ma) ago, the continents had only patches of mosses and algae with no tree cover. The effect of the evolution of trees (large vascular plants with deep, extensive roots) changed the world for ever, according to Dr Robert Berner (Yale University). He presents his findings at... view more (2001-06-21)

CONVERTING WASTE VEGETABLE OIL INTO A USEFUL ENERGY SOURCE
A RESEARCHER in environmental engineering at Staffordshire University has developed a technique to convert unwanted cooking oil into a ‘biodiesel’ which is a much cleaner alternative to fossil diesel. Dr Tarik Al-Shemmeri, a Reader in Environmental Engineering at Staffordshire... view more (2002-09-09)

Three ESA satellites reveal Etna's complexity
As detected by ESA satellite sensors, the recent eruptions of the Mount Etna volcano in Sicily are throwing huge amounts of ash and trace gases into the atmosphere. Working with data from the Global Ozone Monitoring Experiment (GOME) sensor onboard ESA's ERS-2 spacecraft, scientists at the German... view more (2002-10-30)

Researchers discover trees in Amazon much older than assumed, raising questions on global climate impact of region
Trees in the Amazon tropical forests are old. Really old, in fact, which comes as a surprise to a team of American and Brazilian researchers studying tree growth in the world's largest tropical region.   view more (2005-12-14)

Nature Points the way to a sustainable hydrogen economy
"This is an exciting early step in developing a sustainable system for producing electricity from hydrogen" said Professor Chris Pickett (Associate Head of the Biological Chemistry Department at JIC). "In Nature iron-sulphur enzymes catalyse a range of important chemical reactions... view more (2005-02-10)

Ecologists, material scientists pursue genetics of diatom's elegant, etched casing
Diatoms - some of which are so tiny that 30 can fit across the width of a human hair - are so numerous that they are among the key organisms taking the greenhouse gas carbon dioxide out of the Earth's atmosphere.   view more (2008-01-24)

Greenhouse theory smashed by biggest stone
A new theory to explain global warming was revealed at a meeting at the University of Leicester (UK) and is being considered for publication in the journal "Science First Hand".   view more (2006-03-14)

Increase in atmospheric moisture tied to human activities
Observations and climate model results confirm that human-induced warming of the planet is having a pronounced effect on the atmosphere's total moisture content.   view more (2007-09-18)

MIT: Nanoengineered concrete could cut CO2 emissions
While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen.   view more (2007-01-30)

Electrons 'in limbo' seen for first time
Hrvoje Petek, University of Pittsburgh professor of physics and codirector of Pitt's Gertrude E. and John M. Petersen Institute of NanoScience and Engineering (PINSE), has published two papers in recent weeks that literally illuminate how electrons behave on various surfaces.   view more (2006-03-15)

Liquid CO2 drives rapid thrust of diamond-bearing structures
Freeze-dried ice cream looks like the original product, and even tastes pretty good, but "drying" ice cream at room temperature would leave a sour-smelling, sloppy mess.   view more (2007-05-03)

Nitrogen in the air feeds the oceans
A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow?   view more (2005-08-11)

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)

Research Cruise To Understand Major Changes In Atlantic
Scientists at the University of Liverpool are embarking on a research cruise to help them understand recent major changes in the temperature of the Atlantic.   view more (2005-05-10)

Sea level on the rise - in real and virtual worlds
The climate system, and in particular sea level, may be responding more quickly to rising carbon emissions than climate scientists have estimated with climate models.   view more (2007-02-05)

Greenhouse ocean may downsize fish
By 2100, warmer oceans with more carbon dioxide may no longer sustain 1 of the world's most productive fisheries, says USC marine ecologist.   view more (2008-01-14)

Cranking up the volume-- Sounds travel farther underwater as world's oceans become more acidic
It is common knowledge that the world's oceans and atmosphere are warming as humans release more and more carbon dioxide into the Earth's atmosphere. However, fewer people realize that the chemistry of the oceans is also changing--seawater is becoming more acidic as carbon dioxide from the... view more (2008-09-30)

Late life depression associated with blood flow changes in the brain
Depression in later life seems to be associated with changes in blood flow velocity in the main arteries of the brain, shows research in the Journal of Neurology Neurosurgery and Psychiatry. Hardened and thickened arteries, which are more typical in later life, do not explain the findings.   view more (2002-06-25)

Harvard Six Cities Study Follow Up: Reducing Soot Particles Is Associated with Longer Lives
An eight-year follow up to the landmark Harvard Six Cities Study has found an association between people living longer and cities reducing the amount of fine particulate matter, or soot, in their air.   view more (2006-03-16)

The effects of climate change on the physiology of alfalfa
The biologist Gorka Erice Soreasu, a researcher in the Department of Plant Biology of the University of Navarra, has studied the effects of climate change on the physiology of alfalfa.   view more (2006-04-12)

The 'oxygen imperative'
It's common knowledge that humans and other animals couldn't survive without oxygen. But scientists are now learning a good deal more about the extent of our evolutionary debt to a substance that was once a deadly poison.   view more (2006-03-24)

Scientists discover two-component lantibiotic with therapeutic potential
The discovery and preparation of a naturally occurring antibiotic could open the door to new therapeutic drugs for treating nasty infections.   view more (2006-10-31)

Greenhouse gas burial
Deep coal seams that are not commercially viable for coal production could be used for permanent underground storage of carbon dioxide (CO2) generated by human activities, thus avoiding atmospheric release.   view more (2007-06-26)
