"Methane — a greenhouse gas far more potent than carbon dioxide — plays a major
role in controlling the Earth’s climate. But methane concentrations in the
atmosphere today are 150% higher than before the industrial revolution.
In our paper published today in Nature Geoscience, we show as much as half of
global methane emissions come from aquatic ecosystems. This includes natural,
human-created and human-impacted aquatic ecosystems — from flooded rice paddies
and aquaculture ponds to wetlands, lakes and salt marshes.
Our findings are significant. Scientists had previously underestimated this
global methane contribution due to underaccounting human-created and
human-impacted aquatic ecosystems.
It’s critical we use this new information to stop rising methane concentrations
derailing our attempts to stabilise the Earth’s temperature."
