North Sea efficient sink for carbon dioxide
The measured annual increase in the concentration of carbon dioxide (CO2) in the atmosphere is only 60 percent of the annual emissions from fossil fuels.   view more (2005-10-11)

Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times... view more (1999-06-08)

Russian Filter For Russian Exhausts
Automobiles manufactured in Russia are now often equipped with expensive American or European catalytic exhaust scrubbers - converters. However, according the opinion of researchers from the Mendeleyev Russian Chemical-Engineering University, Russian automobiles will be soon equipped with exhaust... view more (2004-06-15)

Cleaning up pollutants with sunlight
A cheap, harmless chemical and sunlight could provide an environmentally friendly way of destroying micro-pollutants in the environment. UK researchers are developing a new type of reactor to destroy persistent contaminants such as pesticides and pharmaceutical residues. The technology, which... view more (2002-10-23)

Gas from the past gives scientists new insights into climate and the oceans
In recent years, public discussion of climate change has included concerns that increased levels of carbon dioxide will contribute to global warming, which in turn may change the circulation in the earth's oceans, with potentially disastrous consequences.   view more (2008-10-06)

New model revises estimates of terrestrial carbon dioxide uptake
Researchers at the University of Illinois have developed a new model of global carbon and nitrogen cycling that will fundamentally transform the understanding of how plants and soils interact with a changing atmosphere and climate.   view more (2007-12-12)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.   view more (2007-10-23)

Beneficial effects of no-till farming depend upon future climate change
By storing carbon in their fields through no-till farming practice, farmers can help countries meet targeted reductions in atmospheric carbon dioxide and reduce the harmful effects of global warming.   view more (2005-10-13)

Global warming plus natural bacteria could release vast carbon deposits currently stored in Arctic soil
Increasing concentrations of carbon dioxide in the atmosphere will make global temperatures rise. By studying soil cores from the Arctic, scientists have discovered that this rise in temperature stimulates the growth of microorganisms that can break down long-term stores of carbon, releasing them... view more (2005-05-05)

Chemical coffee maker promises purer medicines
Their method uses pressurised carbon dioxide as a solvent, because it allows chemical reactions which usually create a mixture of products to produce only one. Project leaders Chris Rayner and Tony Clifford believe it could change the way pharmaceuticals are manufactured in the future. "If the... view more (1999-03-15)

Water detection at Gusev crater described
A large team of NASA scientists, led by earth and planetary scientists at Washington University in St. Louis details the first solid set of evidence for water having existed on Mars at the Gusev crater, exploration site of the rover Spirit.   view more (2005-09-08)

Corals and Climate Change
A modest new lab at the Rosenstiel School is the first of its kind to tackle the global problem of climate change impacts on corals.   view more (2007-08-23)

NORTH ATLANTIC SLOWS DOWN THE GREENHOUSE-EFFECT
What sounds to us like bookkeeping of global change and tedious science, has a big meaning for our climate future. After all, traffic and industrial plants in Europe and North America play a particularly large role in the carbon dioxide pollution of the atmosphere and the greenhouse-effect... view more (1999-06-08)

Asthmatic children in multi-family housing hit by indoor nitrogen dioxide
Children with asthma living in multi-family housing who are exposed to certain levels of indoor nitrogen dioxide, a poisonous pollutant byproduct of gas stoves and unvented heaters, are more likely to experience wheeze, persistent cough, shortness of breath and chest tightness.   view more (2006-02-01)

Strengthening case for life on Mars - CMD19CMMP with The Physics Congress 2002
When it was announced last month that the Mars Odyssey satellite had found water ice beneath the planet`s frozen carbon dioxide south polar ice cap, "I felt excited!" says Dr Lidija Siller, a physicist from the University of Newcastle. "I believe that the data I have explains how this water became... view more (2002-03-26)

Researchers probe a DNA repair enzyme
U. of I. researchers have taken the first steps toward understanding how an enzyme repairs DNA. Enzymes called helicases play a key role in human health, according to Maria Spies, a University of Illinois biochemistry professor.   view more (2008-02-19)

Emissions rising faster this decade than last
The latest figures on the global carbon budget to be released in Washington and Paris today indicate a four-fold increase in growth rate of human-generated carbon dioxide emissions since 2000.   view more (2008-10-02)

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)

Methane doesn't necessarily mean life on Mars, says Dartmouth study
Two Dartmouth researchers have weighed in on the debate over whether the presence of methane gas on Mars indicates life on the red planet. Mukul Sharma, Assistant Professor of Earth Sciences, and Chris Oze, a postdoctoral fellow, argue that the Martian methane could have been produced by inorganic... view more (2005-06-08)

CO2 storage in coal can be predicted better
CO2 storage in the ground is being considered increasingly more often in order to realise the climate and energy objectives. Dutch researcher Saikat Mazumder made it possible to better predict routes of the 'underground highways' along which gasses like carbon dioxide (CO2) and methane (CH4) will... view more (2007-04-16)

Global climate change: a load of poo?
Plankton poo could be the key to understanding how much carbon dioxide our oceans can store according to Tasmanian researcher Dr Karin Beaumont.   view more (2004-09-09)

A link between greenhouse gases and the evolution of C4 grasses
How a changing climate can affect ecosystems is an important and timely question, especially considering the recent global rise in greenhouse gases.   view more (2007-12-21)

Ice core studies confirm accuracy of climate models
An analysis has been completed of the global carbon cycle and climate for a 70,000 year period in the most recent Ice Age, showing a remarkable correlation between carbon dioxide levels and surprisingly abrupt changes in climate.   view more (2008-09-12)

Researchers Predict Future Of Federal Climate Change Policy
The future of federal climate change policy is likely to include a host of strategies such as a national cap on carbon dioxide emissions, mandatory standards on renewable energy, mandatory efficiency standards on vehicles and products, and a national carbon dioxide cap-and-trade scheme, according... view more (2007-02-02)

First ever 'wind scrubbers' to be built
The first phase of a working unit that can remove greenhouse gases from ordinary air is to be completed by the end of this year, according to a report in Chemistry & Industry magazine. Marina Murphy describes the groundbreaking work being done by brothers Allen and Burton Wright (and Burton's... view more (2004-04-02)
