Breaking down the impact of greenhouse gases

It's called the global warming potential or GWP for short and it bundles together the importance of carbon dioxide, methane, and other greenhouse gases on future climate change.  Researchers from DOE's Pacific Northwest ...

Fungi discovered to be source of methane

(Phys.org)—Some six years ago scientific textbooks had to be updated because of the surprising discovery made by the research group led by Frank Keppler that plants produce methane in an oxygen-rich environment. At that ...

Wetlands the primary source of Amazon Basin methane

The Amazon basin is an important sink of carbon dioxide, but it is also a substantial source of atmospheric methane. Tropical wetlands, including those in the Amazon, are one of the largest sources of biogenic methane and ...

A new global warming culprit: Dam drawdowns

Washington State University researchers have documented an underappreciated suite of players in global warming: dams, the water reservoirs behind them, and surges of greenhouse gases as water levels go up and down.

Thawing tundra a new climate threat

(PhysOrg.com) -- A significant source of greenhouse gases has started leaking into the Earth's atmosphere from an unlikely place. Above the Arctic Circle, land frozen for tens of thousands of years has begun to thaw for the ...
