Scientists detect methane surge in South Sudan
Scientists think they can now explain at least part of the recent growth in methane levels in the atmosphere. Researchers, led from Edinburgh University, UK, say their studies point to a big jump in emissions coming from just the wetlands of South Sudan.
Satellite data indicates the region received a large pulse of water from East African lakes, including Victoria. This would have boosted CH4 from the wetlands, accounting for a significant part of the rise in global methane. Dr Mark Lunt spoke to our science correspondent Jonathan Amos.
