Earth Hour dilemma: When the 'like' button harms the planet
Green groups around the world are turning to social networking to drive their campaign for Earth Hour on Saturday, when lights are turned off for an hour to signal concern about global warming.
US sets new carbon standard for power plants
The United States said Tuesday it was setting the first national standards on carbon emissions from power plants, taking aim at the burning of coal which is considered a top culprit in climate change.
Another metric on energy efficiency
It's hardly a surprise that making energy efficiency improvements to buildings saves money and can benefit the environment in terms of reduced fossil fuel burning and reduced greenhouse gas emissions.
Study advances science of carbon accounting
Determining with precision the carbon balance of North America is complicated, but researchers at Oak Ridge National Laboratory have devised a method that considerably advances the science.
Green fuel versus black gold: Is bioethanol more environmentally benign option to petroleum-derived fuels?
A life cycle assessment of growing crops for fuel as opposed to refining and using fossil fuels has revealed that substitution of gasoline by bioethanol converted from energy crops has considerable potential for rendering ...
Peat fires could accelerate climate change: researchers
In 1997, a forest fire in Indonesia ignited an area of peatlands that smouldered for months. By the time it was over, the fire had released greenhouse gases equal to 20 to 40 percent of the total worldwide emissions that ...
Fuel from market waste
Mushy tomatoes, brown bananas and overripe cherries -- to date, waste from wholesale markets has ended up on the compost heap at best. In future it will be put to better use: Researchers have developed a new ...
ASU, Stanford examine implications of bioenergy crops
A team of researchers from Arizona State University, Stanford University and Carnegie Institution for Science has found that converting large swaths of land to bioenergy crops could have a wide range of effects ...
Proposals for reducing carbon dioxide emissions must balance with development needs
Efforts to combat climate change should take into account the development levels of different countries when negotiating agreements, according to a study published in the Dec. 21 issue of the online journal PLoS ONE.
Removing sulfur from jet fuel cools climate: study
A Yale study examining the impact of aviation on climate change found that removing sulfur from jet fuel cools the atmosphere. The study was published in the October 22 issue of Geophysical Research Letters.
Climate talks see some progress as clock ticks
World climate talks late Thursday inched towards common ground that would bring China, the United States and Europe into a deal on tackling global warming.
Fossil-fuel emissions unbraked by financial crisis
Emissions of carbon dioxide (CO2) from fossil fuels and the cement industry scaled a record high in 2010, rocketing by 5.9 percent over 2009 in a surge led by developing countries, scientists reported on Sunday.
Global carbon emissions reach record 10 billion tons -- threatening 2 degree target
Global carbon dioxide emissions from burning fossil fuels have increased by 49 per cent in the last two decades, according to the latest figures by an international team, including researchers at the Tyndall Centre for Climate ...
Geoengineering could save Earth -- or destroy it
(AP) -- Brighten clouds with sea water? Spray aerosols high in the stratosphere? Paint roofs white and plant light-colored crops? How about positioning "sun shades" over the Earth?
