MIT, Harvard offer solution to Mars enigma
Planetary scientists have puzzled for years over an apparent contradiction on Mars. Abundant evidence points to an early warm, wet climate on the red planet, but there's no sign of the widespread carbonate rocks, such as limestone, that should have formed in such a climate.   view more (2007-12-26)

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)

Sinking Greenhouse Gases into the Ocean
"Polarstern" begins new iron fertilization experiment On January 21, 2004, the "Polarstern", research vessel of the Alfred-Wegener-Institute of Polar and Marine Research, will leave Cape Town for the third stage of the 21st expedition to Antarctica. Forty-nine scientists from nine countries... view more (2004-01-21)

Old growth forests are valuable carbon sinks
Contrary to 40 years of conventional wisdom, a new analysis to be published Friday in the journal Nature suggests that old growth forests are usually "carbon sinks" - they continue to absorb carbon dioxide from the atmosphere and mitigate climate change for centuries.   view more (2008-09-11)

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)

Drop in acid rain altering Appalachian stream water
Appalachian hardwood forests may be getting a respite from acid rain but data from a long-term ecological study of stream chemistry suggests that the drop in acid rain may be changing biological activity in the ecosystem and hiking dissolved carbon dioxide in forest streams.   view more (2006-12-12)

New Centre For Satellite Observation Established In North Wales
North Wales is to play a major role in using information from earth-orbiting satellites to improve predictions of future environmental change. The School of Ocean Sciences at University of Wales, Bangor will be part of a national Centre of Excellence in Earth Observation which is to be established... view more (2002-10-17)

Arctic soil reveals climate change clues
Frozen arctic soil contains nearly twice the greenhouse-gas-producing organic material as was previously estimated, according to recently published research by University of Alaska Fairbanks scientists.   view more (2008-10-08)

Regardless of global warming, rising CO2 levels threaten marine life
Like a piece of chalk dissolving in vinegar, marine life with hard shells is in danger of being dissolved by increasing acidity in the oceans.   view more (2007-03-09)

Carnegie Mellon researchers to curb CO2 emissions
Carnegie Mellon University's Chris T. Hendrickson and H. Scott Matthews along with Alex Carpenter and Heather MacLean of the University of Toronto challenge Canadian officials to take the lead in eliminating dangerous carbon dioxide emissions that fuel global warming.   view more (2008-04-03)

Breakthrough in plant research
The research groups of the Department of Biological and Environmental Sciences of the University of Helsinki and the University of California in San Diego have discovered a gene that is centrally involved in the regulation of carbon dioxide uptake for photosynthesis and water evaporation in plants.   view more (2008-02-28)

Dust threatens Kyoto protocol
On the eve of the Earth Summit in Johannesburg, scientists at UCL have detected a flaw in the Kyoto protocol`s global plans to reduce the impact of global warming, all because of something as simple as atmospheric dust. Dr Mark Maslin of UCL`s Environmental Change Research Centre explains: "Dust is... view more (2002-08-07)

Stratified seawater disrupts the transport of imposex substances
Researchers from the University of Amsterdam have demonstrated that the climate in South Mexico changed following the collapse of the Maya empire. From preserved pollen grains the paleoecologists could deduce that the climate quickly became dryer. The climate becoming dryer, explains the decrease... view more (2002-01-24)

Crystal sponges excel at sopping up CO2
Since the Industrial Revolution, levels of carbon dioxide--a major contributor to the greenhouse effect--have been on the rise, prompting scientists to search for ways of counteracting the trend.   view more (2005-12-02)

Detox cure for art treasure
Many museums and churches own pieces of art which were treated with toxic pesticides in the past. Between the 1940’s and 80’s, it was quite usual to protect wood against insects and microorganisms with PCP (pentachlorophenol), DDT and lindane. Though the adverse effect was only... view more (2002-09-09)

Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth.   view more (2008-06-03)

Scientists find key to ocean bacterium that helps control greenhouse gas
Scientists are a step closer to understanding how the world's oceans influence global warming - as well supply us with the oxygen we breathe. A study led by Imperial College London has revealed how the most abundant ocean bound photosynthetic bacterium helps control levels of the greenhouse gas,... view more (2003-08-27)

Storing carbon dioxide below ground may prevent polluting above
A new analysis led by an MIT scientist describes a mechanism for capturing carbon dioxide emissions from a power plant and injecting the gas into the ground, where it would be trapped naturally as tiny bubbles and safely stored in briny porous rock.   view more (2007-02-12)

More carbon dioxide may help some trees weather ice storms
The increased levels of carbon dioxide in the atmosphere predicted for later this century may reduce the damage that future ice storms will cause to commercially important loblolly pine trees, according to a new study.   view more (2006-08-16)

Experiment suggests limitations to carbon dioxide 'tree banking'
While 10 years of bathing North Carolina pine tree stands with extra carbon dioxide did allow the trees to grow more tissue, only those pines receiving the most water and nutrients were able to store significant amounts of carbon that could offset the effects of global warming, scientists told a... view more (2007-08-07)

RAND study: Alternative fossil fuels have economic potential
Alternative sources of fossil fuels such as oil sands and coal-to-liquids have significant economic promise, but the environmental consequences must also be considered, according to a RAND Corporation study issued today.   view more (2008-10-08)

Study Finds Plenty of Carbon Dioxide Storage Capacity Underground in Kentucky
As concern has grown over the effects of the human release of carbon dioxide (CO2) gas into the atmosphere, so too has research into technologies to manage CO2.   view more (2006-10-09)

LSU, Yale team study agricultural impact on Mississippi River
According to a study published in "Nature" by researchers at LSU and Yale University, farming has significantly changed the hydrology and chemistry of the Mississippi River, injecting more carbon dioxide into the river and raising river discharge during the past 50 years.   view more (2008-01-24)

Northern forests less effective than tropical forests in reducing global warming
Forests in the United States and other northern mid- and upper-latitude regions are playing a smaller role in offsetting global warming than previously thought, according to a study appearing in this week's issue of Science.   view more (2007-06-25)

Increased carbon dioxide in atmosphere linked to decreased soil organic matter
A recent study at the University of Illinois created a bit of a mystery for soil scientist Michelle Wander - increased carbon dioxide in the atmosphere was expected to increase plant growth, increase plant biomass and ultimately beef up the organic matter in the soil -- but it didn't.   view more (2008-03-12)
