Curbing coal emissions alone might avert climate danger, say researchers
An ongoing rise in atmospheric carbon dioxide from burning of fossil fuels might be kept below harmful levels if emissions from coal are phased out within the next few decades, say researchers. view more (2008-09-15)
Emission reduction assumptions for carbon dioxide overly optimistic, study says
Reducing global emissions of carbon dioxide (CO2) over the coming century will be more challenging than society has been led to believe, according to a new research commentary appearing April 3 in Nature. view more (2008-04-03)
Decline in greenhouse gas emissions would reduce sea-level rise, save Arctic Sea ice
The threat of global warming can still be greatly diminished if nations cut emissions of heat-trapping greenhouse gases by 70 percent this century, according to a new analysis. view more (2009-04-15)
Global warming predicted to hasten carbon release from peat bogs
Billions of tons of carbon sequestered in the world's peat bogs could be released into the atmosphere in the coming decades as a result of global warming, according to a new analysis of the interplay between peat bogs, water tables, and climate change. view more (2008-11-07)
Emission Reduction Assumptions for Carbon Dioxide Overly Optimistic, Study Says
Reducing global emissions of carbon dioxide (CO2) over the coming century will be more challenging than society has been led to believe, according to a research commentary appearing this week in the journal Nature. view more (2008-04-03)
Global sunscreen won't save corals
Emergency plans to counteract global warming by artificially shading the Earth from incoming sunlight might lower the planet's temperature a few degrees, but such "geoengineering" solutions would do little to stop the acidification of the world oceans that threatens coral reefs and other marine life. view more (2009-06-17)
Antarctic krill provide carbon sink in Southern Ocean
New research on Antarctic krill (Euphausia superba), a shrimp-like animal at the heart of the Southern Ocean food chain, reveals behaviour that shows that they absorb and transfer more carbon from the Earth's surface than was previously understood. view more (2006-02-07)
Oceans' uptake of manmade carbon may be slowing
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. view more (2009-11-19)
Greenhouse gas bubbling from melting permafrost feeds climate warming
A study co-authored by a Florida State University scientist and published in the Sept. 7 issue of the journal Nature has found that as the permafrost melts in North Siberia due to climate change, carbon sequestered and buried there since the Pleistocene era is bubbling up to the surface of Siberian thaw lakes and into the atmosphere as methane, a... view more...

Study critiques corn-for-ethanol's carbon footprint
To avoid creating greenhouse gases, it makes more sense using today's technology to leave land unfarmed in conservation reserves than to plow it up for corn to make biofuel, according to a comprehensive Duke University-led study. view more (2009-03-03)
Stratospheric injections could help cool Earth, computer model shows
A two-pronged approach to stabilizing climate, with cuts in greenhouse gas emissions as well as injections of climate-cooling sulfates, could prove more effective than either approach used separately. view more (2006-09-15)
Canada's new government invests in carbon capture research delivering real results on greenhouse gas
The Honourable Gary Lunn, Minister of Natural Resources, along with partners from Innoventures Canada (I-CAN), today announced funding for a project related to the initial development of the I-CAN Centre for the Conversion of Carbon Dioxide (CO2), at the Economic Club in Calgary. view more (2007-03-13)
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)
Leaving our mark
Whether you live in a cardboard box or a luxurious mansion, whether you subsist on homegrown vegetables or wolf down imported steaks, whether you're a jet-setter or a sedentary retiree, anyone who lives in the U.S. contributes more than twice as much greenhouse gas to the atmosphere as the global average, an MIT class has estimated. view more (2008-04-29)
Biodiesel won't drive down global warming
EU legislation to promote the uptake of biodiesel will not make any difference to global warming, and could potentially result in greater emissions of greenhouse gases than from conventional petroleum derived diesel. view more (2007-04-23)
Increased atmospheric carbon dioxide promotes algal growth
It is usually thought that unlike terrestrial plants, submerged plants like algae will not show any response to an increase of atmospheric carbon dioxide. This view may be biased by a neglect of the effects of the plants themselves on the water chemistry. In the June issue of Ecology Letters, Schippers, Lürling and Scheffer of the Wageningen... view more... (2004-05-13)
Motorcycles emit 'disproportionately high' amounts of air pollutants
Motorcycles collectively emit 16 times more hydrocarbons, three times more carbon monoxide and a "disproportionately high" amount of other air pollutants compared to passenger cars. view more (2005-12-20)
Groundbreaking Canada-US study proves link between emissions and mercury pollution in fish
A groundbreaking environmental study to be published in a prestigious American science journal proves that mercury atmospheric emissions will end up in fish in as little as three years. view more (2007-09-18)
The Antarctic Canary — the human impact on climate change
As the UK attempts to move towards a low carbon economy, leading scientists and a world expert on sustainable energy in buildings this week discuss the evidence for climate change and possible solutions. view more (2006-09-05)
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)
