Research casts doubt on global warming benefits of biofuels made cornfield waste
2014-04-20 20:10:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Biofuels made from the leftovers of harvested corn plants are worse than gasoline for global warming in the short term, a study shows, challenging the Obama administration's conclusions that they are a much cleaner oil alternative and will help combat climate change. A $500,000 study paid for by the federal government and released Sunday in the peer-reviewed journal Nature Climate Change concludes that biofuels made with corn residue release 7 per cent more greenhouse gases in the early years...

Study casts doubt on climate benefit of biofuels from corn residue
2014-04-20 12:00:00| Climate Ark Climate Change & Global Warming Newsfeed
PhysOrg: 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. The findings by a University of Nebraska-Lincoln team of researchers cast doubt on whether corn residue can be used to meet federal mandates to ramp up ethanol production and reduce greenhouse gas emissions. Corn stover-the stalks, leaves and cobs in cornfields after harvest-has been considered...

Huge Methane Leaks Add Doubt on Gas as Bridge Fuel
2014-04-16 00:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Natural gas as a means to produce electricity is being hailed by the Intergovernmental Panel on Climate Change as the fuel that can act as a "bridge" between carbon-heavy coal and zero-carbon renewables, helping to reduce humans' impact on the climate. The idea is that burning natural gas involves fewer greenhouse gas emissions than burning coal. The IPCC in its Working Group III report says natural gas as a bridge fuel will only be effective if few gases escape into the atmosphere during natural...
