Studies find different reasons for global methane riddle

Two new UC Irvine papers reach markedly different conclusions about why methane, a highly potent greenhouse gas, unexpectedly leveled off near the end of the 20th century. They appear today in the journal Nature.

Greenhouse gas impact of hydroelectric reservoirs downgraded

An international team of scientists has amassed the largest data set to date on greenhouse gas emissions from hydroelectric reservoirs. Their analysis, published today in the online version of Nature Geoscience, posits that ...

Soil microbes accelerate global warming

More carbon dioxide in the atmosphere causes soil to release the potent greenhouse gases methane and nitrous oxide, new research published in this week's edition of Nature reveals. "This feedback to our changing atmosphere ...

Wetlands are bad and good news for Arctic warming: study

(PhysOrg.com) -- Seasonal wetlands in Arctic regions will initially persist longer due to global warming but then shrink as temperatures rise further, according to new study into how climate change will progress this century.

Methane gas from cows -- the proof is in the poo

Scientists could have a revolutionary new way of measuring how much of the potent greenhouse gas methane is produced by cows and other ruminants, thanks to a surprising discovery in their poo.

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.
