Water vapor confirmed as major player in climate change
Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. view more (2008-11-18)
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)
Atmosphere threatened by pollutants entering ocean, prof says
A large quantity of nitrogen compounds emitted into the atmosphere by humans through the burning of fossil fuels and the use of nitrogen fertilizers enters the oceans and may lead to the removal of some carbon dioxide from the atmosphere. view more (2008-05-16)
Ocean's 'twilight zone' plays important role in climate change
A major study has shed new light on the dim layer of the ocean called the "twilight zone"—where mysterious processes affect the ocean's ability to absorb and store carbon dioxide accumulating in our atmosphere. view more (2007-04-27)
Global Warming Surpassed Natural Cycles in Fueling 2005 Hurricane Season, NCAR Scientists Conclude
Global warming accounted for around half of the extra hurricane-fueling warmth in the waters of the tropical North Atlantic in 2005, while natural cycles were only a minor factor. view more (2006-06-23)
Yale report cites emerging carbon finance market
Climate change is an unprecedented global problem and an emerging carbon finance market will play a critical role in addressing it, asserts a newly published Yale report. view more (2008-11-07)
Grasslands won't help buffer climate change as carbon dioxide levels rise
Because grasslands and forests operate in complex feedback loops with both the atmosphere and soil, understanding how ecosystems respond to global changes in climate and element cycling is critical to predicting the range of global environmental changes-and attendant ecosystem responses-likely to occur. view more (2005-08-09)
Trade-offs reveal no clear favorites in alternative energy market
The nuclear power industry is riding the green wave back into public favor with its promise of a low-carbon solution to our growing energy needs. But even as the industry struggles to dictate what role nuclear can realistically play, it is bound by a global energy landscape-from solar to carbon sequestration-that is still predominantly shaped by... view more...

Family planning a major environmental impact
Some people who are serious about wanting to reduce their "carbon footprint" on the Earth have one choice available to them that may yield a large long-term benefit - have one less child. view more (2009-08-03)
Fires in far northern forests to have cooling, not warming, effect
Droughts and longer summers tied to global warming are causing more fires in the Earth's vast northernmost forests, a phenomenon that will spew a steadily increasing amount of carbon dioxide into the atmosphere. view more (2006-11-17)
Fertilizers - a growing threat to sea life
New study on landscape around Chesapeake Bay says imbalance in nitrogen cycle is damaging water quality and fish populations. view more (2008-10-22)
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)
Microbe has huge role in ocean life, carbon cycle
Researchers at Oregon State University and Diversa Corporation have discovered that the smallest free-living cell known also has the smallest genome, or genetic structure, of any independent cell-and yet it dominates life in the oceans, thrives where most other cells would die, and plays a huge role in the cycling of carbon on Earth. view more (2005-08-19)
Antarctica glacier retreat creates new carbon dioxide store
Large blooms of tiny marine plants called phytoplankton are flourishing in areas of open water left exposed by the recent and rapid melting of ice shelves and glaciers around the Antarctic Peninsula. view more (2009-11-10)
Southern Ocean could slow global warming
The Southern Ocean may slow the rate of global warming by absorbing significantly more heat and carbon dioxide than previously thought, according to new research. view more (2006-12-06)
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)
Loose grip
Carbon dioxide (CO2) is contained in the air we exhale, and is also always formed when carbon-containing substances such as oil, gas, wood, and plastics are burned - it is omnipres-ent. Chemists have long been trying to convert this gas to something useful, and Koji Tanaka and coworkers from the Institute for Molecular Science in Myodaiji, Japan,... view more... (1999-01-28)
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)
An unexpected outcome of atmospheric CO2 enrichment
Unseen belowground interactions impact the composition of natural plant communities. Mycorrhizae, symbiotic associations between soil fungi and plant roots, help plants acquire soil nutrients but also drain substantial carbon from plants. Whether mycorrhizae help or hinder plant growth depends upon the balance between nutrient benefits and carbon... view more... (2003-05-22)
Kyoto will have little effect on global warming
Life expectancy and prosperity will continue to rise and food production should keep up with population growth, but the Kyoto agreement will have little effect on global warming according to this week's Christmas issue of the BMJ. Using official statistics and global trends, Bj'¸rn Lomborg, Director of the Danish Environmental Assessment Institute... view more... (2002-12-18)
