Falling water levels trigger a surge in methane emissions from Mediterranean reservoirs

Continental aquatic ecosystems, such as lakes and reservoirs, occupy a small proportion of Earth's surface but play a significant role in the global carbon cycle.

It is estimated that more than 40% of global methane emissions originate from these ecosystems.

However, the true scale of these emissions remains uncertain, as most of the available data comes from one-off measurements taken at specific times and locations. ...
