First U.S. execution by nitrogen gas would cause "painful and humiliating death," U.N. experts warn » Experts have denounced Alabama's planned execution of a death row inmate by nitrogen hypoxia — an untested suffocation method that they say could cause "grave suffering." Cbsnews.com

Methane and NOx Emissions from Natural Gas Stoves, Cooktops, and Ovens in Residential Homes » Natural gas stoves in >40 million U.S. residences release methane (CH4)─a potent greenhouse gas─through post-meter leaks and incomplete combustion. We quantified methane released in 53 homes during all phases of stove use: steady-state-off (appliance not in use), steady-state-on (during combustion), and transitory periods of ignition and extinguishment. We estimated that natural gas stoves emit 0.8–1.3% of the gas they use as unburned methane and that total U.S. stove emissions are 28.1 [95% confidence interval: 18.5, 41.2] Gg CH4 year–1. More than three-quarters of methane emissions we measured originated during steady-state-off. Using a 20-year timeframe for methane, annual methane emissions from all gas stoves in U.S. homes have a climate impact comparable to the annual carbon dioxide emissions of 500 000 cars. In addition to methane emissions, co-emitted health-damaging air pollutants such as nitrogen oxides (NOx) are released into home air and can trigger respiratory diseases. In 32 homes, we m Pubs.acs.org
