Two new preprints trace microbes in tropical wetlands—which are getting wetter with ClimateChange—as the source of rising methane emissions.
story, especially the surge in East Africa. When combined with smaller increases from the Amazon and the northern forests, it largely explains the observed rise in the atmosphere.Nature Communicationsfrom 2010 to 2019, measured by satellite, synced up with a temperature pattern in the Indian Ocean that periodically warms the waters off the Horn of Africa, causing increased rainfall on land.
Ed Dlugokencky, an atmospheric chemist at ESRL, agrees East African wetlands may well play a big role in the methane emissions of the past 2 years. “But the question of whether it’s a climate feedback yet is very difficult to answer,” simply because of limited records and large yearly variations in rainfall and wetland emissions. Nisbet notes, though, that the same dynamic may be playing out across other tropical wetlands. “A warming world is a wetter world in the moist tropics,” Nisbet says.
