Human alterations to aquatic ecosystems increase methane emissions

Atmospheric methane has tripled since pre-industrial times. It traps heat far more effectively than carbon dioxide and accounts for 25 percent of atmospheric warming to date, and much of that methane is coming from aquatic ecosystems, with human activities contributing to the emissions levels, a new paper published in Nature Geoscience has found. The global contribution and importance of aquatic ecosystems as methane emitters […]
