Modest CO2 cutbacks may be too little, too late for coral reefs
How much carbon dioxide is too much? According to United Nations Framework Convention on Climate Change (UNFCCC) greenhouse gases in the atmosphere need to be stabilized at levels low enough to "prevent dangerous anthropogenic interference with the climate system." But scientists have come to realize that an even more acute danger than... view more... (2008-09-23)
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)
Alarming growth in expected CO2 emissions in China, finds UC analysis
The growth in China's carbon dioxide (CO2) emissions is far outpacing previous estimates, making the goal of stabilizing atmospheric greenhouse gases even more difficult, according to a new analysis by economists at the University of California, Berkeley, and UC San Diego. view more (2008-03-11)
North Atlantic slows on the uptake of CO2
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia. view more (2007-10-23)
Boat tail reduces truck fuel consumption by 7.5 percent
An articulated lorry was driven for a period of one year with a boat tail (of varying length) and one year without a boat tail. The improved aerodynamics, depending on the length of the boat tail, resulted in reduced fuel consumption (and emissions!) of up to 7.5 percent. The optimum boat tail length proved to be two metres. view more (2009-11-06)
Cold storage solution for global warming?
Researchers from the University of Leicester and the British Geological Society (BGS) have proposed storing CO2 in huge underground reservoirs as a way of reducing emissions- and have even identified sites in Western Europe that would be suitable. view more (2007-02-07)
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 move. view more (2007-04-16)
A dash of lime -- a new twist that may cut CO2 levels back to pre-industrial levels
Scientists say they have found a workable way of reducing CO2 levels in the atmosphere by adding lime to seawater. And they think it has the potential to dramatically reverse CO2 accumulation in the atmosphere, reports Cath O'Driscoll in SCI's Chemistry & Industry magazine published today. view more (2008-07-21)
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)
Smithsonian scientists report new carbon dioxide study
Researchers at the Smithsonian Environmental Research Center report the results of a six-year experiment in which doubling the atmospheric greenhouse gas carbon dioxide (CO2) in a scrub oak ecosystem caused a reduction in carbon storage in the soil. view more (2007-03-13)
Beyond CO2: Study reveals growing importance of HFCs in climate warming
Some of the substances that are helping to avert the destruction of the ozone layer could increasingly contribute to climate warming. view more (2009-06-23)
Engineered weathering process could mitigate global warming
Researchers at Harvard University and Pennsylvania State University have invented a technology, inspired by nature, to reduce the accumulation of atmospheric carbon dioxide (CO2) caused by human emissions. view more (2007-11-08)
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)
Increasing residential and employment density could mean reductions in vehicle travel, fuel use and CO2 emissions
Increasing population and employment density in metropolitan areas could reduce vehicle travel, energy use, and CO2 emissions from less than 1 percent up to 11 percent by 2050 compared to a base case for household vehicle usage. view more (2009-09-01)
Carnegie Institution
The future of the Earth could rest on potentially dangerous and unproven geoengineering technologies unless emissions of carbon dioxide can be greatly reduced, a new study has found. view more (2009-09-01)
Major international study warns global warming is destroying coral reefs and calls for 'drastic actions'
If world leaders do not immediately engage in a race against time to save the Earth's coral reefs, these vital ecosystems will not survive the global warming and acidification predicted for later this century. That is the conclusion of a group of marine scientists from around the world in a major new study published in the journal Science on Dec.... view more... (2007-12-26)
Verification of national methane estimates now possible
New methods for verifying estimated greenhouse gas emissions, developed by scientists at Royal Holloway, University of London, will play a significant role in assessing reductions in methane emissions, important in national compliance with Kyoto protocol targets. David Lowry, Craig Holmes, Nigel Rata and Euan Nisbet of Royal Holloway’s... view more... (2001-04-25)
Avoiding the hothouse and the icehouse
By controlling emissions of fossil fuels we may be able to greatly delay the start of the next ice age, new research from the Niels Bohr Institute at University of Copenhagen concludes. view more (2009-02-11)
Complex carbon picture clearer
Study shows that more plant litter resulting from higher CO2 could boost the amount of carbon released into the atmosphere. view more (2007-12-12)
Focus on methane to save the planet
SMALL print in the Kyoto Protocol threatens to make global warming more severe than it need be over the next 10 years or so. An obscure rule is discouraging countries from applying cheap technologies that could dramatically curb global warming in the short term, warns a British climate scientist.... view more...
