Ceramic tubes could cut greenhouse gas emissions from power stations
Greenhouse gas emissions from power stations could be cut to almost zero by controlling the combustion process with tiny tubes made from an advanced ceramic material. view more (2007-08-03)
Greenhouse gas effect consistent over 420 million years
New calculations show that sensitivity of Earth's climate to changes in the greenhouse gas carbon dioxide (CO2) has been consistent for the last 420 million years, according to an article in Nature by geologists at Yale and Wesleyan Universities. view more (2007-03-29)
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)
Rovers begin new observations on changing Martian atmosphere
Mars rover scientists have launched a new long-term study on the Martian atmosphere with the Alpha Particle X-ray Spectrometer, an instrument that was originally developed at the University of Chicago. view more (2007-08-30)
Climate swings have brought great CO2 pulses up from the deep sea
May 10, 2007, The Earth Institute at Columbia University—A study released today provides some of the first solid evidence that warming-induced changes in ocean circulation at the end of the last Ice Age caused vast quantities of ancient carbon dioxide to belch from the deep sea into the atmosphere. view more (2007-05-14)
Ocean acidification may contribute to global shellfish decline
Relatively minor increases in ocean acidity brought about by high levels of carbon dioxide have significant detrimental effects on the growth, development, and survival of hard clams, bay scallops, and Eastern oysters, according to researchers at Stony Brook University's School of Marine and Atmospheric Sciences. view more (2009-10-27)
Prehistoric global warming may have contributed to fossil preservation
Prehistoric global warming episodes from massive atmospheric pollution involving carbon dioxide and methane could have created and preserved "mass kills" of wildlife, according to a University of Oregon study presented at the Geological Society of America's annual meeting. view more (2005-10-13)
CO2 emissions booming, shifting east, researchers report
Despite widespread concern about climate change, annual carbon dioxide emissions from burning fossil fuels and manufacturing cement have grown 38 percent since 1992, from 6.1 billion tons of carbon to 8.5 billion tons in 2007. view more (2008-09-25)
Sudden collapse in ancient biodiversity: Was global warming the culprit?
Scientists have unearthed striking evidence for a sudden ancient collapse in plant biodiversity. A trove of 200 million-year-old fossil leaves collected in East Greenland tells the story, carrying its message across time to us today. view more (2009-06-19)
Carbon sinks: Issues, markets, policy
With reducing carbon emissions on the national agenda, a group of expert panelists will discuss methods, markets, testing and policy issues on how carbon sinks or carbon sequestration may be used to reduce atmospheric CO2. view more (2008-09-29)
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)
Scientists Discover What Plants Do During Long Winter Nights
In research published today scientists at the John Innes Centre (JIC), Norwich(1), report on what plants do during the hours of darkness. During daylight hours plants use the energy from sunlight to power the production of food (sugar) from carbon dioxide and water. This process (photosynthesis) is well understood, but what happens when the sun... view more... (2003-12-29)
New materials can selectively capture carbon dioxide, UCLA chemists report
UCLA chemists report a major advance in reducing heat-trapping carbon dioxide emissions in the Feb. 15 issue of the journal Science. view more (2008-02-15)
Ice sheets drive atmospheric carbon dioxide levels, inverting previous ice-age theory
In the early 20th century, Milutin Milankovitch, a leading astronomer and climatologist of the time, proposed that the Earth's ice-age cycles could be predicted because they correspond directly with routine changes in the Earth's orbit and its tilt over cycles of tens of thousands of years. view more (2006-07-25)
Mixed prairie grasses are better biofuel source, U of M study says
Highly diverse mixtures of native prairie plant species have emerged as a leader in the quest to identify the best source of biomass for producing sustainable, bio-based fuel to replace petroleum. view more (2006-12-08)
Application quantifies carbon sequestration of urban trees
U.S. Forest Service scientists at the Center for Urban Forest Research are providing online software that can show users how much carbon dioxide an urban tree in California has sequestered in its lifetime and the past year. view more (2008-12-10)
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)
Potent greenhouse gas more prevalent in atmosphere than previously assumed
A powerful greenhouse gas is at least four times more prevalent in the atmosphere than previously estimated, according to a team of researchers at Scripps Institution of Oceanography at UC San Diego. view more (2008-10-24)
Climate gas could disrupt food chain
Levels of a climate cooling gas will change as carbon dioxide increases, affecting food webs along the way, said Dr Michael Steinke at a Science Media Centre press briefing today. view more (2007-12-11)
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 atmosphere dissolves in the oceans. view more (2008-09-30)
