Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Scientists see urgent need for reducing emissions
(Phys.org) —The bad news: a major transformation of our current energy supply system is needed in order to avoid a dangerous increase in global temperatures. The good news: the technologies needed to get ...

After racing against the clock in an all-night session, the U.N.'s expert panel on climate change was putting the final touches Saturday on a scientific guide to help governments, industries and regular people ...
Climate: Farming emissions to rise 30 percent by 2050
Greenhouse gases emitted by agriculture are on track to rise by 30 percent by mid-century, driven especially by livestock and use of fertiliser, a UN agency reported on Friday.
From theory to reality: Carbon capture utilization and storage
In spite of calls for urgent action to reduce carbon dioxide emissions to mitigate the effects of climate change, little attention and funding has been given to a technological solution that can take this ...
Carbon cuts possible for manageable warming, experts say
The world, acting urgently, can curb carbon emissions enough to avert worst-case scenarios for climate change, UN experts said Monday as envoys met in Berlin to weigh the options for action.
The tiniest greenhouse gas emitters

(Phys.org) —The total warming impact of 25 major synthetic greenhouse gases has been examined by an international team, led by researchers from the University of Bristol.
Gauging the impact of tropical forest logging: Winrock develops new method for quantifying carbon emissions
Researchers at Winrock International have developed a first-of-its-kind method for estimating carbon emissions from forest degradation caused by selective logging in tropical regions. Refined over a period of 15 years and ...
Americans using more energy, analysis shows
(Phys.org) —Americans used more renewable, fossil and even nuclear energy in 2013, according to the most recent energy flow charts released by Lawrence Livermore National Laboratory.
Using more wood for construction can slash global reliance on fossil fuels
A Yale University-led study has found that using more wood and less steel and concrete in building and bridge construction would substantially reduce global carbon dioxide emissions and fossil fuel consumption.
Researcher takes measure of carbon storage in Iceland
The idea of capturing carbon and storing it away offers an appealing solution to the "greenhouse gas" emissions from fossil fuels that are warming the planet. But how can we measure the process well enough ...
New planes could cut aviation carbon emissions
Policies that encourage airlines to replace the old planes in their fleet with newer models could lead to substantial cuts in aviation carbon emissions, according to new research.
