Thawing permafrost produces more methane than expected

Methane (CH4) is a potent greenhouse gas that is roughly 30 times more harmful to the climate than carbon dioxide (CO2). Both gases are produced in thawing permafrost as dead animal and plant remains are decomposed. However, ...

NASA-led study solves a methane puzzle

A new NASA-led study has solved a puzzle involving the recent rise in atmospheric methane, a potent greenhouse gas, with a new calculation of emissions from global fires. The new study resolves what looked like irreconcilable ...

NASA spots single methane leak from space for the first time

For the first time, an instrument onboard an orbiting spacecraft has measured the methane emissions from a single, specific leaking facility on Earth's surface. The observation—by the Hyperion spectrometer on NASA's Earth ...

New light-activated catalyst grabs CO2 to make ingredients for fuel

Scientists have developed a light-activated material that can chemically convert carbon dioxide into carbon monoxide without generating unwanted byproducts. The achievement marks a significant step forward in developing technology ...

Study: Biodegradable products may be bad for the environment

Research from North Carolina State University shows that so-called biodegradable products are likely doing more harm than good in landfills, because they are releasing a powerful greenhouse gas as they break down.
