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 ...
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 ...
The tiniest greenhouse gas emitters
Climate feedbacks from decomposition by soil microbes are one of the biggest uncertainties facing climate modelers. A new study from the International Institute for Applied Systems Analysis (IIASA) and the ...
Little-studied man-made gases have big warming potential
(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.
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.
Water treatment could be carbon neutral
Carbon dioxide released by some wastewater treatment plants could be recycled at the same time as enhancing the production of renewable energy in the form of natural gas, say scientists.
Meeting climate targets may require reducing meat and dairy consumption
Greenhouse gas emissions from food production may threaten the UN climate target of limiting global warming to 2 degrees Celsius, according to research at Chalmers University of Technology, Sweden.

US to tackle methane in climate change push (Update)
The White House pledged Friday to clamp down on US emissions of methane, a greenhouse gas produced by cattle and natural gas production that contributes to climate change.
Oil seed can slash CO2 emissions in farming by 13%
According to the initial results of EU-funded research the use of rapeseed cake in the production of livestock feed can cut methane and carbon dioxide emissions by up to 13%. This is the preliminary finding ...
Lots of carbon dioxide equivalents from aquatic environments
Large amounts of carbon dioxide equivalents taken up by plants on land are returned to the atmosphere from aquatic environments. This is the conclusions from a study carried out by two students at Linköping University, Sweden.
