Latest research finds plant debris in lake sediment affects methane emissions. The flourishing reed beds created by changing climates could threaten to double the already significant methane production of the world’s northern lakes.
Declining calcium levels in some North American lakes are causing major depletions of dominant plankton species, enabling the rapid rise of their ecological competitor: a small jelly-clad invertebrate. Scientists say increasing ‘jellification’ will damage fish stocks and filtration systems that allow lakes to supply drinking water, and that lakes may have been pushed into “an entirely new ecological state”.
The subglacial lakes are the first to be identified in Greenland.
