Methane concentration rise in atmosphere slowing down

Scientists say levels have been stable for about seven years following a steep rise during the last century.

Researchers believe the slowdown may be due to measures aimed at reducing the release of methane from gas pipelines, paddy fields and landfill sites.

The findings are published in the journal Geophysical Research Letters.

The study also found that major forest fires, such as occurred in Indonesia in 1997 and 1998, produce significant quantities of methane.
