Swimming on the edge: endurance swimmer takes on melting glaciers

What does it take to get the world’s attention on climate change? Lewis Pugh thinks swimming across a supra-glacial lake in East Antarctica might. The pioneer swimmer—and United Nations Environment Programme (UNEP) Patron of the Oceans—embarked on a gutsy 1-kilometre swim across a river, which has formed as a result of melting ice caused by climate change.

New insights into how global change is impacting freshwater environments

A new global study sheds light on how interactions between specific characteristics of catchments, such as carbon and pollution, affect aquatic plant diversity and function in freshwater environments.

Photosynthesis in many aquatic plants relies on bicarbonate (HCO3−) in addition to carbon dioxide (CO2). The study investigates the link between the two and their impact on  plant distribution.

Using green technology to improve water quality in Kenya’s Mtwapa Creek

“The smell alone when you cross the bridge tells you something’s wrong,” says Renison Ruwa, deputy director of the Kenya Marine and Fisheries Research Institute.

The bridge in question is Mtwapa bridge, which straddles Mtwapa Creek in Mombasa, Kenya. And the smell to which Ruwa is referring stems from this very creek, into which waste from the nearby Shimo la Tewa prison—and indeed many other places—is directly dumped.
