Carbon dioxide emissions predicted to reduce density of Earth's outermost atmosphere by 2017
Carbon dioxide emissions from the burning of fossil fuels will produce a 3 percent reduction in the density of Earth's outermost atmosphere by 2017, according to a team of scientists from the National Center for Atmospheric Research (NCAR) and Pennsylvania State University (PSU).   view more (2006-12-12)

Planting carbon deep in the earth -- rather than the greenhouse
Storing carbon dioxide deep below the earth's surface could be a safe, long-term solution to one of the planet's major contributors to climate change.   view more (2007-11-27)

Researchers at the University Jaume I put environmentally-friendly refrigerants to the test
Keeping food cool in the fridge or switching on the air conditioning at the office can be costly for the environment. The gases that have been used up till now for refrigeration (mainly the so-called HCFCs, such as R22) contain high proportions of chlorine, one of the elements responsible for the... view more (2004-06-28)

New earth observation centres announced
Two new centres which will use satellites and models to help forecast earthquakes and the effects of carbon in climate change were announced (Wednesday 17 October) by Lord Sainsbury, Science & Innovation Minister. Said Lord Sainsbury, " I am delighted to announce that the Natural... view more (2001-10-19)

Cooking with gas may increase inflammatory activity in the lungs
Cooking with gas may increase inflammatory activity in the lungs, suggests a study in Occupational and Environmental Medicine. Teflon filters were used to collect any particulate matter pollution emitted from gas and electric cookers. The residue was then applied to cultured cells that normally... view more (2001-02-10)

Thawing permafrost increases greenhouse gas emission from subarctic mires
The permafrost in the mires of subarctic Sweden is undergoing dramatic changes. The part of the soils that thaws in the summer, the so-called active layer, has become deeper since 1970 and the permafrost has disappeared altogether in some locations. This has lead to significant changes in the... view more (2004-02-24)

A WAKE-UP CALL FOR ENVIRONMENTAL HEALTH (p 587)
Issue 23 August 2003 Embargoed 0001 h (London time) 22 August 2003. This week's editorial comments on the new energy bill that will increase US domestic energy supply, concluding that the bill's implications for increased energy consumption rather than conservation is 'a step backwards for... view more (2003-08-20)

Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world.   view more (2007-07-10)

Global warming is reducing ocean life, increasing atmospheric carbon dioxide, say scientists
Alarming new satellite data show that the warming of the world's oceans is reducing ocean life while contributing to increased global warming.   view more (2006-12-07)

Solvents in Retreat
A new catalyst for selective solvent-free hydrogenation at low temperatures A number of cyclic hydrocarbons with multiple double bonds are readily accessible intermediates in chemical industry. In the course of further processing it is often necessary to saturate some of the double bonds with... view more (2001-03-27)

Amazon outflow is found to power ocean capture of carbon dioxide
Nutrients washed out of the Amazon River are powering huge amounts of previously unexpected plant life far out to sea, thus trapping atmospheric carbon dioxide, according to a new study.   view more (2008-07-24)

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)

Brown Scientists Say Biodiversity Is Crucial to Ecosystem Productivity
In the first experiment involving a natural environment, scientists at Brown University have shown that richer plant diversity significantly enhances an ecosystem's productivity.   view more (2008-04-25)

First-ever study to link increased mortality specifically to carbon dioxide emissions
A Stanford scientist has spelled out for the first time the direct links between increased levels of carbon dioxide in the atmosphere and increases in human mortality, using a state-of-the-art computer model of the atmosphere that incorporates scores of physical and chemical environmental processes.   view more (2008-01-04)

Nitrous oxide from ocean microbes
A large amount of the greenhouse gas nitrous oxide is produced by bacteria in the oxygen poor parts of the ocean using nitrites, Dr Mark Trimmer told journalists at a Science Media Centre press briefing today.   view more (2007-12-11)

Hold your breath; Plants may absorb less carbon dioxide than we thought
The world's land plants will probably not be able to absorb as great a share of the rising atmospheric carbon dioxide as some models have predicted.   view more (2006-04-13)

Insects take a bigger bite out of plants in a higher CO2 world
Atmospheric carbon dioxide levels are rising at an alarming rate, and new research indicates that soybean plant defenses go down as CO2 goes up. Elevated CO2 impairs a key component of the plant's defenses against leaf-eating insects, according to the report.   view more (2008-03-25)

Groundbreaking research in Scotland
A £5.85 million pound study of the soil in the Cheviot Hills has finally come to an end, producing a huge wealth of new information for scientists.   view more (2004-03-31)

Aloe vera coating may prolong freshness, safety of fruits and vegetables
